Abstract: PURPOSE:To considerably improve accuracy for measurement by providing a second process to measure a substrate current by impressing a voltage at a second level higher than a first level to a substrate, and a third process to calculate the charge/voltage converting efficiency based on a ratio between an output voltage and the substrate current. CONSTITUTION:A substrate pulse PS at a low level VL is impressed to an N type silicone substrate 2, and at such a time, an output voltage VOUT of an output part 24 is measured by a voltmeter 26 at an output terminal 25. Continuously, the substrate pulse Ps at a high level VH is impressed to the N type silicone substrate 2 at prescribed timing and by impressing this substrate pulse PS, a potential barrier is destroyed so that signal charges stored in a photosensitive part 3 are swept out onto the N type silicone substrate 2. At such a time, a substrate current ISUB to flow is measured by an ammeter 22 at a substrate terminal 21. Then, converting efficiency eta is calculated based on the obtained substrate current ISUB and the output voltage VOUT. Thus, the method for measuring charge/voltage converting efficiency can be obtained to considerably improve accuracy for measurement.

Filed: 1987-10-14
Abstract: PURPOSE: To make it possible to directly display a graphic on a screen by increading the luminance of a part corresponding to the segment of a scanning line only by luminance display width. CONSTITUTION: When the coordinates of a segment start point and a segment end point are specified, luminance display width is computed in accordance with the inclination of a straight line passing the two coordinate positions at first, and when the scanning of a scanning line corresponding to the coordinates of the segment start point is started, the luminance of a part corresponding to the segment of the scanning line is increased only by the luminance display width. The operation for succeeding scanning lines is repeated up to a scanning line corresponding to the coordinates of the segment end point. Consequently a segment such as a straight line can be directly displayed on a screen based upon segment parameters such as the coordinates of the segment start and end points and a segment plotter eliminating the necessity of a video RAM or the like can be attained.

Title: Battery case
Inventor: TANAKA HARUMI
IPC: H01M2/10
Filed: 1994-09-29
Abstract: PURPOSE:To provide a battery case capable of preventing an accident such as explosion, breakdown of equipment or the like due to reverse loading of a battery. CONSTITUTION:Electrode contacts 21, 22 are disposed at the top surface of a battery case 3 containing cylindrical batteries 1, 1, and are connected to positive and negative electrodes of the cylindrical batteries 1, 1 contained inside and connected in series to the case 3. When the electrode contacts 21, 22 are rotated at 180 deg. around a center line between the cylindrical batteries in parallel inside the battery case 3, they are located at positions not corresponding to the electrode contacts before the rotation. Consequently, when the battery case 3 is loaded in the reverse direction in a device such as a camera, the electrode contacts 21, 22 are not brought into contact with connection terminals of the device, thus preventing an accident such as explosion, breakdown or the like of the device.

Title: Mechanism for adjusting seat belt anchor in passive seat belt device
Inventor: SHIMOKI KAZUAKI
IPC: B60R22/06
Filed: 1987-10-14
Abstract: PURPOSE:To enable suitable adjustment under a belt fitting condition to be made in a simple manner by drawing a transfer cable to a no-belt fitting position by a specified length in such a way that a moving anchor under the belt fitting condition becomes free against the transfer cable within an anchor adjuster. CONSTITUTION:When a shoulder anchor adjuster 40 is adjusted in position, an adjuster knob 68 is moved up and down while leaving a push button pressed in, following which, the push button is released from its pressed condition at the optimum position which meets the physical feature of a driver, then, both an anchor bracket 61 and a slide base also start moving up and down so that a locking pawl is engaged with an engaging hole again. Concurrently, an adjuster switch 57 is turned off so that the motor is reversely actuated. Then, the reverse motion allows the anchor to be pulled back until the upper end of the engaging hole 26 of a tape 25 abuts against a head section 22 so as to let both a buckle detecting switch 71 and a tang detecting switch be turned off for suspending the motor. This constitution enables the position of the anchor 40 to be appropriately adjusted with ease in such a way as to meet the physical feature while leaving the shoulder belt fitted.

Abstract: PURPOSE:To reliably perform the capping of a recording means by providing a locking means for locking a door so that its open state cannot be changed to a closed state and vice versa and making the locking means effective during a period of time when a power source is not switched on. CONSTITUTION:When a main power source switch is kept ON, a solenoid 23 attracts a movable iron piece 24 to be in an unlocked state in response to a signal from a control unit, and the opening of a door 20 can be freely done. When the main power source switch is turned OFF after the door 20 is completely closed, a power to the solenoid 23 is also interrupted, whereby the movable iron piece 24 is liberated to be projected, and the claw of the movable iron piece enters an engaging hole 31 of a locking member 21, so that the locking member 21 can be neither opened nor closed. In the case where the main power source switch is turned OFF when it has been in the ON state and the door 20 has been opened, the liberated movable iron piece 24 is projected to check the movement of the locking member 21; therefore, the closing of the door 20 becomes impossible.
