A dipping type wafer treatment apparatus includes a treatment solution bath capable of forming a uniform rising flow of a treatment solution inside from an inlet to an outlet, a treatment solution supplying unit for supplying a treatment solution at a constant velocity to the inlet of the treatment solution bath to form a uniform rising flow of the treatment solution inside the treatment solution bath and a device for dipping and retrieving the wafer into and out of the uniform flow of the treatment solution. The treatment solution is supplied from the inlet in the treatment solution bath and drown off through an outlet of the treatment solution bath. Accordingly, the treatment solution can be rapidly substituted, and the wafers to no experience contact with air during replacement of the treatment solutions.

A key telephone system having an off-hook announcing function comprises a main unit and a plurality of standard key telephone sets each connected to the main unit. In the system, the main unit includes a plurality of digital telephone interface circuits connected to the key telephone sets and also a voice addition circuit. When one telephone set issues an off-hook announcement to another telephone set, the voice addition circuit adds together the voice signals received from the telephone sets and transmits the resultant added voice signal to yet another telephone set to provide to that telephone set an off-hook announcement.

The present invention relates to an electronic stringed musical instrument with a string vibration detecting device, such as an electronic guitar, guitar synthesizer, electronic violin, etc. A string supporting unit for supporting and fixing at least one end of stretched strings is removably mounted on a body unit. A string vibration detecting device and an electronic processing substrate, such as a printed board, are removably mounted on the string supporting unit.

A vibration plate and cushioning plate are arranged, as a layered structure, within a drum shell in that order as viewed from the inner bottom of the drum shell toward a batter head with a vibration sensing/electric signal producing sensor attached to the vibration plate. A cushioning member is located within the drum shell to elastically support the cushioning plate between the inner bottom surface of the drum shell and the vibration plate. The cushioning member includes an externally urging section for externally urging the vibration plate toward the drum shell and an elastic support section which, when receiving an external strike force exceeding a predetermined value, is elastically deformed toward the inner bottom surface of the drum shell.

In a compact liquid crystal television receiver having an information memory, map information, train time table information, or telephone directory information is prestored in the information memory, and is read out therefrom as needed. The readout information data is displayed on a screen, instead of a television image. In the case, window display can be used. The information memory is an IC card, and a still image audio or characters by character broadcasting can be recorded or reproduced.

A saturable reactor is in a conductive state or has a magnetic switching function depending on the direction of the current flowing through it. Also provided is a power source apparatus for pulse laser utilizing the satiable reactor. The saturable reactor comprises a saturable magnetic core (1); a principal coil (2) wound around the saturable magnetic core (1); a subsidiary coil (3) wound around the saturable magnetic core (1); and a power source (4) which feeds electric current (ib) to the subsidiary coil (3) when the transition of the saturable magnetic core (1) from unsaturated state to saturated state is effected by the subsidiary coil (3) wherein the saturable magnetic core (1) becomes saturated state immediately when a current (i2) is applied to the principal coil (2) in a direction same as the current flowing in the subsidiary magnetic coil (3), while becoming the saturated state from an initial unsaturated state at the time when a product of the voltage and time reaches a predetermined value if a current (i1) is applied to the principal coil (2) in a direction opposite to the current flowing in the subsidiary magnetic coil (3).

A fingerboard and a neck for an electronic musical instrument according to the present invention are used for an electronic musical instrument, such as an electronic guitar, an electronic violin, and a guitar synthesizer. A flexible sheet made of a slippery material is formed on the upper surface of a fingerboard incorporating a plurality of pitch designating means so as to allow smooth and quick fingering. A plurality of frets are formed on the upper surface of the flexible sheet so as to partition the pitch designating means.

Flexible cylindrical magnetic members are detachably attached on one of paired string support units, both of which are mounted on an instrument body to stretch strings therebetween, to face a string-vibration pickup device of an electromagnetic type. A string member is passed through each of the inner holes of the cylindrical magnetic member, and vibrations of the string are picked up by the pickup device through the cylindrical magnetic member to be outputted as electrical signals through the pickup device. Musical sounds are electrically or electronically generated by a sound source responsive to the electrical signals.
