A method of manufacturing a semiconductor chip that has electrode pads on the chip front surface and disposed inside a conductive outer ring. A film circuit is disposed on the chip front surface side. External connection thermals are formed on the film circuit so as to project there from. First leads electrically connect part of the electrode pads to part of the external connection terminals. A second lead electrically connects a grounding or power supply electrode pad to the outer ring, and a third lead electrically connects a grounding or power supply external connection terminal to the outer ring.

A connector for memory cards includes a connector body having side walls on both sides and a rear wall. The side walls are formed over their length with card receiving portions to meet shapes of side edges and the number of the memory cards to be used. The connector further includes card identification terminals made of a springy metal strip arranged in a plurality of steps in inner surface of one of the side walls, identification tabs arranged spaced from the card identification terminal prior to insertion of a card, for identifying an existence of an inserted card with the aid of the contact between the inserted card and the card identification terminal, and terminals suitably arranged on the rear wall for writing electronic information into cards and reading stored information from cards. Each of the card identification terminals includes a contact portion to contact the card, a fixing portion to be fixed to the connector body, and a connection portion to be connected to a board and further includes an engaging portion on an extension of the contact portion, which engaging portion engages an anchoring portion of each of insertion grooves formed in the connector body.

A method of manufacturing a semiconductor device includes the step of doping an N-type impurity via a selective region formed on a semiconductor substrate by lithography, the step of doping a P-type impurity in the semiconductor substrate subsequent to the doping step without forming a selective region by lithography, and the step of self-aligningly forming an N-diffusion layer and a P-diffusion layer by performing wet oxidation with respect to the semiconductor substrate in which the N-type impurity and the P-type impurity are doped.

A shift lever device includes a shift lever which allows selection of an arbitrary shift range by shift operation and which is rotatably supported by a structure that breaks when an axial impact force above a preselected magnitude is applied to the shift lever. The breakage of the supporting structure allows safer absorption of an impact force applied to the shift lever. The breakable supporting structure may take the form of a portion of a thin portion of a circular wall forming a bearing that rotatably supports the shift lever, or a frangible pin or bracket that pivotably supports the shift lever.

A scroll compressor in which each of its stationary and swivel scrolls has at least one recess formed in the inner surface of its wrap adjacent to an area of wrap engagement or disengagement. The recess has an inclined edge extending at an angle to the end plate upon which each lap stands upright. The recess enables the wraps to have gradually changing lines of contact with each other along their heights to prevent undesirable noise or vibration during their engagement or disengagement.

A remote control system comprises an audio apparatus audio signal, a video apparatus, a remote input device, a selector, and an output device wherein the remote input device transmits a position specification signal to the selector. The selector is connected to the audio and video apparatus and receives the position specification signal from the remote input device. The memory portion stores picture data include mode setting data for setting operation modes of the audio and video apparatus, command codes associated with the operation modes, and selection picture data for selecting the audio apparatus or Video apparatus. When the control portion detects that the position specification signal input by the remote input device indicates a predetermined position, it reads picture data in accordance with the input position specification signal from the memory portion. The command generation portion then selectively supplies a command code to the audio apparatus or video apparatus in accordance with the input position specification signal. The output device has a display portion to which the picture data read by the control portion from the memory portion are supplied, and the output signal of either the audio apparatus or video apparatus selected by the selector is supplied to the output device. When the control portion of the selector detects that the position specification signal input by the remote input device is a signal indicating the position corresponding to any one of the four sides of the display portion with the picture data of either the audio apparatus or video apparatus displayed on the display device, either the picture data associated with the other apparatus or the selection picture data are read from the memory portion and are displayed on said display portion.

Disclosed is an automated image gray level transformation system applied to a medical image processing work station for the purpose of dispensing with the prior art manual complex processing thereby improving the accuracy of diagnosis. The system carries out, in addition to its fundamental step of equalizing a histogram of image data of an input image, the steps of suppressing an adverse effect of a background region of the image so as to obtaining an intensity transformation function, constraining the intensity transformation function and modifying a bias value used for the function constraining.

A thin-film magnetic head is disclosed wherein a first core portion includes an insulative island of inorganic material. A first coil section is formed in the island so that it presents a flat common surface with the island and substrate. A gap-forming insulating layer is on the first coil section and the first core portion. A second core portion is on the gap-forming layer, forming a magnetic circuit with the first core portion. A second coil section is connected to the first coil section to form a coil therewith. In a modification, the head comprises a nonmagnetic substrate in which a coil section is formed to present a flat common surface. Metallic ferromagnetic material is used to form core portions on the coil section.

A Hall effect magnetic head performs predetermined operations such as recording, reproducing and erasing of data on a recording medium which is capable of magnetically recording data therein. The magnetic head includes first and second magnetic members which define therebetween a front gap which faces the recording medium, a space in which a magnetic field developing means is disposed, and a rear gap in which a Hall element is disposed. The Hall element is applied with a bias magnetic field developed by the magnetic field developing means and by a signal magnetic field developed by the recording medium. The Hall element comprises a vertically magnetizable thin layer or film and is caused to output as a Hall voltage a signal contained in the signal magnetic field. The front and rear gaps are adequately dimensioned to increase the Hall voltage. The magnetic head may include second magnetic field developing means for preventing the bias magnetic field from influencing the recording medium.

A color imaging apparatus having a plurality of image pickup tubes which pick up respective optical images of primary colors separated from one optical image includes a registration control circuit which operates to hold a picture of high quality at all times by controlling the registration of the images of the respective image pickup tubes on a real time basis during the operation of the camera. To this end a circuit detects those local image signals which satisfy predetermined requisites which are most favorable for use as reference signals to control the registration and these detected image signals are temporarily stored so as to be used for the registration operation. The most favorable requisites of the local image areas selected for registration control are (1) those having no movement, (2) those having a contour which is sharp and (3) those having a chroma which is low.
