In an electronic still camera employing a CCD, an automatic exposure control and an automatic focusing control are carried out by utilizing an image signal derived from CCD to photograph a subject. A liquid crystal display unit is provided within a viewfinder. A designation is performed on a subject image to be automatically controlled for the exposure and focusing operations by utilizing a frame displayed on the liquid crystal display unit. The automatic exposure control and automatic focusing control are executed with respect to the subject positioned within the frame displayed on the liquid crystal display unit.

An obstacle detection system has a sensor unit including a plurality of ultrasonic transducers and sequentially changes the number of pulses provided to groups of transducers, thereby performing front center sensing, front right sensing and front left sensing. The time between emission of ultrasonic waves and reception of waves reflected by an obstacle is calculated by a timer. A microcomputer computes the distance data and position data of the obstacle in accordance with obtained timer data and sensing region data.

A die of a coating apparatus for applying a coating solution includes down- and upstream blocks in a feeding direction of a web, which respectively have a first lip and a second lip. A lip land of the first lip is shorter than a lip land of the second lip in the feeding direction so as to satisfy a predetermined condition. In assembling the coating apparatus, bottoms of down- and upstream blocks are fixed to a fixer with bolts. Between the fixer and the downstream block, a plate member is provided such that the first lip land protrudes from the second lip land.

The mounting is formed by grinding an integrally molded material with accuracy of the μm order. An upper portion of the mounting is an L-shaped holding portion on which a slot die is positioned. An upper face of the holding portion contacts a lower facer of the slot die, and a side face of the holding portion contacts a rear face of the slot die. The lower and rear races of the slot die and the upper and side faces of the holding portion are formed to have such a straightness for the total length that the unevenness thereof may be in 5 μm. Thus the slot die can be held with high accuracy, and the clearance accuracy between the lips and a web can be increased.

The present invention is intended to provide an EIA method utilizing bioluminescence using a firefly luciferase. The EIA method of the present invention is characterized by using an ATP-generating enzyme as a labeling enzyme, subjecting ATP generated to bioluminescence by the use of the firefly luciferase, and measuring the quantity of light emitted. Acetate kinase is a preferred enzyme used in the method.

An obstacle sensing area ahead of a mobile robot is divided into a plurality of sensing regions. A number of ultrasonic transmitters and plural receivers on the robot cooperate to detect the presence of obstacles in the sensing regions. Coordinates representing four corners of each sensing region, and time data representing a time period from emission of ultrasonic waves from selected transmitters to reception of the waves by each receiver when the waves are reflected by an obstacle at each corner point, are prestored in data ROMs. The data ROMs are retrieved by a CPU in response to obtained time data, and precise position data of the obstacle in the sensing area is determined.

A character signal including sixteen binary coded signal blocks each with an additional bit is stored in a closed loop memory and displayed, as corresponding characters on a display. In response to the display, a student strikes keys on a keyboard to deliver signal blocks, similar in coded form to the stored ones, to a comparator where they are successively compared with corresponding stored signal blocks. Upon the correct striking of the keys, the comparator applies a coincidence signal to the memory to change the value of the additional bit to erase the associated displayed character. Upon incorrect striking of the keys the changed bit is changed back to the original value to again display all the characters on the display.
