Title: Elastic surface wave resonator
Inventor: ETSUNO MASAYOSHI
IPC: H03H9/02
Filed: 1984-06-06
Abstract: PURPOSE:To reduce the increase in a floating capacitance by grounding substantially an electrode finger of an interdigital electrode to a surface acoustic wave reflector. CONSTITUTION:A comb line electrode 23 having the electrode finger 2301 nearest to the reflectors 24, 25 is grounded. Even if an electric field is produced between the reflectors 24, 25 in the electrically floating state, since a comb line electrode 23 is at a ground potential, the capacitors C1, C2 are short-circuited by a lead 31 and capacitors C3, C4 are short-circuited by a lead 32. Thus, the electrode capacitance of an interdigital transducer (IDT) has a value C0 depending on the total length of the cross electrode finger so as to reduce the electric coupling between the IDT and the reflectors thereby decreasing the floating capacitance. The increase in the substantial insertion loss is prevented and it is prevented to narrow the variable range of an oscillating frequency section when the resonator is used as an oscillating element.

IPC: G03B7/08
Filed: 1989-05-09
Abstract: PURPOSE:To shorten a focusing time by exhausting an electrical signal generated in an area other than the prescribed area of an image pickup element at high speed, and detecting the state of incident light by outputting only the electrical signal generated in the prescribed area sequentially.

Abstract: PURPOSE: To easily recover lost control data peculiar for the machine and to shorten the time for control when a machine is installed by simultaneously writing the control data into first and second memory spaces without inputting any password. CONSTITUTION: In the case of performing first control when the device is installed, the switch button of a data input device 4 is depressed while pushing a key for backup mode. This operation is the first operation for reloading the control data in the first memory space.

Abstract: PURPOSE:To accurately detect even the concn. of gas having a wide absorption spectrum band, by measuring transmissivity difference using two oscillation modes. CONSTITUTION:In measuring gas having large transmissivity difference and a wide wavelength band in absorption spectrum such as c4H10, a laser current is set so as to extend over two oscillation modes M2, M3 oscillated by an oscillation control circuit 20.

Filed: 1977-09-27
Abstract: PURPOSE: To prevent the unnecessary display of a number of film frames by detecting the presence or absence of a film patrone, cartridge or magazine, and controlling the transmission to a plate of number of frames for display of counter operation.  
     CONSTITUTION: When film patrone (cartridge or magazine) 10 is not loaded in the camera, interlocking rod 22 connected with patrone detector 13 is moved by the elastic force of spring 26 so as to swing feeding claw member 16 via pin 25 of the interlocking rod 22. Consequently, feeding claw 18a which rotates the claw wheel 15 integral with the display scale 12 of number of films is moved to the position where the claw 18a is unable to be engaged with the claw wheel 15 via feeding member 18 which interlocks with winding-up of the film. Therefore the transmission of the counter mechanism to the scale 12 when the patrone is unloaded is inhibited, hence the prevention of display of unnecessary number of frames can be carried out in a simple constitution
