Title: Automatic gain control circuit
Inventor: KOYAMA TOORU
IPC: H03G3/20
Filed: 1980-02-01
Abstract: PURPOSE:To decrease the return time at steady-state, by limiting the amplitude from the limiter when an input signal is rapidly increased from the limiter and a surge is input to the input. CONSTITUTION:The input signal from the line (a) is amplified by the gain determined with the level of the line (d) with a variable gain control amplifier 1 and becomes the output signal of (b). When the output signal level of (b) is increased than the level of the line (c), a current flows to a resistor 2 and a diode 3, a capacitor 4 is charged with the time constant determined with the resistor 2, and the level of the line (c) is increased, the output (d) of an amplifier 7 is increased and the gain of the amplifier 1 is decreased. In this case, a limiter 8 is provided which makes limit with a slightly higher level than the reference voltage, allowing the limiter 8 to limit the amplitude, if the input signal is rapidly increased and a surge is input to the input. Thus, the capacitor 4 is charged to a slightly higher value than the reference voltage, allowing to reduce the time returned at the steady-state.

IPC: B42D15/10
Filed: 1987-01-22
Abstract: PURPOSE:To realize the input/output of information for various types of IC cards without suppressing the memory capacity at the side of a transaction device, by providing a means to the IC card to store a special input/output program and performing input/output processing of information based on said program. CONSTITUTION:When an IC card 1 is put into an IC card reader/writer 23 of a transaction device, a CPU 15 controls the reader/writer 23 to decode the initial data outputted from the card 1 and to select a handler used for input/ output of information. This handler is stored in a different IC card B and therefore the CPU 15 gives an indication to replace the cards via a display device 19, etc. Then an operator inserts the card B storing the handler into the reader/ writer 23. Thus a handler needed for input/output of information on an IC card A is sent from the card B and loaded into a RAM 18. The CPU 15 starts the loaded handler and performs the input/output of information again based on the protocol of the replaced desired card A.

Title: Pressure sensor
Inventor: OKUMA SHIGEO
IPC: G01D3/028
Filed: 1991-01-07
Abstract: PURPOSE:To detect the pressure while preventing errors in a detecting signal from the temperature change by using a piezoelectric body of a d15-model having a signal shaft in the axial direction, and a polarization shaft and a stress shaft in the radial direction. CONSTITUTION:A conical cylinder part 16D with a conical space 16C is formed at an upper end of a pressure receiving rod 16. The conical cylinder part 16D shifts outward in the radial direction in accordance with the shift of a diaphragm 13 and converts the shift of the diaphragm 13 in the axial direction to the stress in the radial direction. A piezoelectric body 19 of a d15 model is provided at an upper end of the conical cylinder part 16D. The piezoelectric body 19 has a signal shaft in the axial direction and, a polarization shaft and a stress shaft in the radial direction. Accordingly, the shift of the diaphragm 13 in the axial direction can be converted to the stress in the radial direction by the conical cylinder part 16D of the pressure receiving rod 16. The stress acts on the stress shaft of the piezoelectric body 19 thereby to generate electric charges in a direction of the polarization shaft. As a result, a voltage signal corresponding to the burning pressure can be output from the signal shaft in the axial direction orthogonal to the polarization shaft.

Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent a finger from being put on a focal-plane shutter film so as to prevent the separation of the film by maintaining the shutter film in an open state when a back cover is opened. SOLUTION: When the back cover is opened, a back cover switch S1 senses it and outputs a corresponding signal to a control part 2. The control part 2 inputs a signal from the switch S1 and outputs a control signal for making the focal-plane shutter film in the open state to a shutter driving part 3. When the back cover 2 is closed, the control part 2 inputs the corresponding signal from the switch S1 and outputs the control signal for recovering the focal-plane shutter film to an initial state to the driving part 3. Namely, when the back cover is opened, both a front film and a rear film are maintained in a folded state so as to prevent the separation of the film.

Filed: 1978-02-04
Abstract: PURPOSE:To enable to perform three types signals to deliver, by using two frequency signals with a simple constitution, through counting with the counter after the reception of N signal and through the discrimination to the three types of information depending on the level of rectified output. CONSTITUTION:A number of transmission stations (T1)...(Tn) and reception stations (R1)...(Rn) are connected on the delivery line, and the signals R and N are outputted with the control circuit. On the other hand, the transmission station and the reception station build in the counter respectively, and the counter is reset when the signal R is received and the counter starts counting when the signal N is received. Further, the level of the rectified output discriminates no signal, information corresponding to one frequency signal, and information corresponding to the coexistence of the signal in both frequencies. Thus, three types of signal transmission can be made by using two frequency signals with a simple constitution.

Abstract: PURPOSE:To improve the wiring rate of route search based upon a maze method by repeating processing for determining the routes of all required connections by successively increasing a 1st and 2nd increment values until a prescribed route setting state is set up. CONSTITUTION:In the case of setting up a new route, a label value is increased one by one every passage through a cell not included in existing routes from one cell to the arrival of the other cell, and when a route to be newly set up crosses the existing route at the time of passing the cell included in the existing route, the 1st prescribed increment value is added to the label value to obtain a label value. When the new route does not cross, the label value is obtained by adding the 2nd prescribed increment value to obtain a new label value to obtain a new label value, the route of the minimum label value at the time of arrival of the other cell is set up as a newly set route and processing for determining the routes of all required connections is repeated by successively increasing the 1st and 2nd increment values until the prescribed route setting state can be obtained.
