IPC: G11B20/14
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a clock generating device eliminating a band-pass filter for every zone, for generating an internal clock of an optical recording medium of a ZCAV(zoned constant angular velocity) system. SOLUTION: A clock generating signal f(1)+Δf(1) extracted from the zone i=1 is mixed with 70MHz-f(1) by a mixer 17 to be frequency-converted into a frequency band of 70MHz. The f(1) is a reference frequency of the zone i=1 to be generated from a PLL 12. The Δf(1) is an error frequency. After a 70MHz+Δf(1) component is extracted by a SAW filter 20, is mixed with 70MHz-f(1) again by the mixer 18, and the noise removed f(1)+Δf(1) is obtained, and it is inputted to the PLL 30, and a recording/reproducing clock signal is generated. Since it is noise-removed after frequency converting into a narrow band by using a known f(i) (i=1 to n), plural band-pass filters at every f(i) are eliminated. The SAW filter 20 is designed so that Q is large, and a phase delay amount is fixed.

Title: Device for controlling operation in refrigerating apparatus
IPC: F25B1/00
Filed: 1992-03-31
Abstract: PURPOSE:To prevent instability in the control which may arise from frequently intermittent operation of the compressor in the system where control makes the temperature of a medium undergoing heat exchange constant at the outlet of the heat exchanger for the refrigerated space. CONSTITUTION:When a stop-controlling means 51 stops the compressor 1, the temperature at the outlet at the time of the stopping is stored as a stop temperature in a stop temperature- storing means 52. At the time that a specific period of time has elapsed after the stopping, the difference between the temperature at the outlet and the stop temperature is stored as a reference temperature difference in a reference temperature difference-storing means 53. When the change of the temperature at the outlet from the stop temperature exceeds the reference temperature difference by a specified value, a reset-controlling means 54 makes the compressor 1 resume its operation. When the reference temperature difference determined as above exceeds a certain multiple of the average of the reference temperature differences in preceding times of the stopping, a change of the temperature at the outlet from the stop temperature that exceeds the average temperature difference causes the compressor 1 to resume its operation. This method keeps the temperature at the outlet at an appropriate value when the compressor resumes the operation, stabilizes the control, and keeps the temperature of the medium undergoing the heat exchange appropriate.

Title: Input circuit
Inventor: MATSUMURA TAKASHI
IPC: H03F3/34
Filed: 1982-05-06
Abstract: PURPOSE:To keep an input current at a fixed level regardless of variation of the current amplification factor of an input transistor (TR), by using an input current mirror circuit in place of a TR similar to an input TR and a flow-out type constant current source. CONSTITUTION:TRs 13-15 form a current mirror circuit. The base current of a TR15 is absorbed by a constant current source 16, and therefore a current I2XhFEP flows to the emitter of the TR15 as well as to the TR14. Therefore the full collector current of the TR13 is equal to I2XhFEP if the emitter area is equal between the TRs 13 and 14. Then a current I2XhFEP/2 flows to emitters of TRs 3 and 4 respectively. Thus the input current to the bases of TRs 3 and 4 is set at I2XhFEP/2/hFEP=I2/2 since TRs 15, 3 and 4 have equal charge amplification factor hFEP. This input current is equal to constant 1/2 current of the source 16. As a result, no effect is received from the variation of the current amplification factor to ensure a constant input current.

Abstract: PURPOSE: To make cursol display more efficient and simpler and expand the working range of discharge tubes by making the cathode current of the display discharge tube variable and providing a difference in the luminance between input information display part and other display part.  
     CONSTITUTION: Clock pulses from a generator 1 are divided down 2 to form reset pulses. In response to the both pulses, a cathode driving circuit 3 distributes the pulses, a cathode driving circuit 3 distributes the pulses so as to match the number  of eathodes of bar graph panel 6' and gives lighting signal subsequently from the  reset electrodes. On the other hand, when the input signal coincides with the reference voltage from a generator 4' in a comparator 5', an output is supplied to a  single pulse generating circuit 7', the single pulse whereof operates an anode driving  circuit 8', thereby increasing discharge current. If at this time the width of the  single pulse is made equal to the width of the cathode pulses, only the specified  cathode lights with high luminance, thereby enabling the width of the cursor to be  taken large.

IPC: H01P7/04
Filed: 1987-03-30
Abstract: PURPOSE:To obtain a filtering device miniaturized, and by which a high damping quantity can be obtained, and with superior group delay characteristic in a passing band, by coupling a surface acoustic wave(SAW filter) in series with a dielectric filter. CONSTITUTION:A dielectric filtering device is constituted by housing a coupling substrate 3 consisting of plural dielectric resonators 2 and a dielectric to capacitive-couple the resonators 2, and the SAW filter 4 mounted on the substrate 3 in a case 1. And when a high power of certain frequency is inputted to the dielectric filtering device, it is filtered first at the resonator 2. At this time, the high input power is damped to a power level at which a filter 4 can stand. Next, filtering is applied on the power at the filter 4, and it is outputted from an electrode 10 on an output side. At this time, since the number of stages of the resonator 2 is reduced than ever, and also, the group delay time of the filter 4 is flat in the passing band, it is possible to improve the group delay characteristic in the passing band.
