Title: Variable semiconductor capacitor
Inventor: MATSUO HIROMI
IPC: H01L29/93
Filed: 1987-08-27
Abstract: PURPOSE:To obtain the characteristics of variable capacitance having excellent linearity and low series resistance, by forming layers having the same conductivity type stepwise on a semiconductor substrate, forming a layer having the reverse conductivity type, and providing a structure whose conductivity becomes higher as said layers having the same conductivity approach the conductor layer at the surface from the bulk of the semiconductor substrate. CONSTITUTION:An N-type diffused layer 9 is formed between an N-type epitaxial growing layer 2 and an N-type diffused layer 3. Thus, the layers having the same conductivity type are formed stepwise in stages. In this structure, the impurity concentration region of the N-type diffused layer having a wide field of view is formed on the side of the N-type epitaxial growing layer 2 in comparison with a conventional element structure. The total amount becomes larger than in the conventional structure. The series resistance at this part is decreased. Therefore, when this capacitor is used, e.g., in an electronic tuning circuit for a tuner and the like, the range of a variable voltage is wide, and tracking errors can be reduced. Since the series resistors are implemented, a performance index Q of a circuit including the variable semiconductor capacitor can be made high.

Abstract: PURPOSE:To make a recorder small in size and to enable a satisfactory recording, by a method wherein a recording material supply device detachably loaded with a cartridge containing a recording material reads encoder scales provided on a mount and drives a recording means. CONSTITUTION:A cartridge 7 containing a recording material 3 is detachably loaded on a mount 2, encoder scales 4, 5 are provided on the mount 2, and a recording material supply device 1 is prepared separately from a recorder 13. In this manner, the recorder 13 does not require an ink ribbon and an encoder disk, thus being enabled to be made small in size and to be manually scanned with a small scanning power. In a handy recording system, the encoder scales 4, 5 are read by a photointerupter 17, and according to this detection signal a heating element 14a of a recording head 14 is driven to execute recording. In this manner, the travel condition of the recorder 13 is assuredly detected without being affected by the slip of the recorder 13, which enables satisfactory recording to be carried out.

Title: Focusing detection safety device of single-lens reflex camera
Inventor: MATSUTANI TOSHIOKI
IPC: G03B13/36
Filed: 1981-12-29
Abstract: PURPOSE:To secure focusing by providing a selective limiting means which when either one of a manual operating member and a preview operating member is operated, disables the other to operate or disables prescribed operation by the operation of the other. CONSTITUTION:When an FD operating member is pressed in, a focusing detecting member 24 moves left to close a switch 28, and consequently while a focusing detector starts operating, a lock lever 30 rotates clockwise against a spring 34 to fit its upper projection part 30b in the cut 20c of the preview operating member 20, engaging a step part 20d. Thus, the preview operating member 20 is inhibited from moving left. On the other hand, when the preview operating member is pressed in, the preview operating member 20 moves left to rotate an aperture operating member 18 clockwise, and the cut 20c of the member 20 also moves to position the member 20 over the upper projecting part 30b of a lock lever 30, so the lock lever 30 is disallowed to rotate clockwise, so that the focusing detection member 24 and FD operating member are both disallowed to operate.

IPC: G11C7/00
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To automatically give the priority sequence to execute any instruction desired even when the PUSH (write) signal and POP (read) signal are issued simultaneously. SOLUTION: When the PUSH signal and POP signal are issued simultaneously, since the PUSH signal is supplied first to a PUSH counter 1, write operation is instructed to a single RAM 4. In the digital control circuit 5, upon completion of the PUSH signal, the POP signal is supplied to a chip selector CE of the POP counter 2. Therefore, even when the PUSH signal, POP signal are issued simultaneously, the PUSH signal becomes automatically effective with priority and thereafter the POP signal becomes effective.

Title: Ultrasonic level meter
Inventor: ISHIDA YOSHIZO
IPC: G01F23/28
Filed: 1990-08-10
Abstract: PURPOSE:To measure the liquid level with good accuracy by providing a float of a smaller specific gravity than a liquid in a container, and a reflecting plate of a larger specific gravity than the liquid which is suspended from the float in a swaying fashion. CONSTITUTION:An ultrasonic pulse generated from an ultrasonic probe 6 at the bottom of a container 1 is reflected by a reflecting plate 10 suspended from a float 8, and received again by the probe 6. The distance (m) between the probe 6 and reflecting plate 10 is obtained by measuring the time since the pulse is generated until it is received by the probe 6. Even when the height of the float 8 is changed in accordance with the increase/decrease of the storing amount of a liquid 2, the distance (l) between the float 8 and reflecting plate 10 is constant. Therefore, the distance between the probe 6 and liquid surface is (m+l). Moreover, as more bubbles are present near the liquid surface, it is possible to face the reflecting plate 10 to the probe 6 at the position other than where the air bubbles are present if the distance (l) between the float 8 and reflecting plate 10 is set suitably. The influences of the air bubbles can be removed. In this manner, the liquid level can be measured with high accuracy.
