Abstract: PURPOSE:To improve the cutoff performance at the high frequency side, by insulating an end of each of >=2 parallel resonators consisting of coils and capacitors froem a shielding case to connect them to each other and opening the other end respectively. CONSTITUTION:A shielding case 8 contains 4 rooms 11 and 12, and the rooms 11 at both ends of the case 8 include the parallel resonators 15 and 15' with the capacitors 14 and 14' connected to both ends of the coils 13 and 13', and an input winding 16 and an output winding 17 with an end connected to the case 8 and the other end insulated from the case and then drawn outside respectively. A coupling window 18 is formed to a partition wall 9 between the room 11 and the center room 12, and the parallel resonators 21 and 21' consisting of the coils 19, 19' and the capacitors 20, 20' connected to both ends of the coils 19 and 19' are disposed in the room 12. As no window is provided to a partition wall 10 of the room 12, the resonators 21 and 21' are separated from each other in terms of the electric field. Then an end of each of the resonators 21 and 21' is connected to each other to have an electromagnetic connection. The other end of each of the resonators 21 and 21' is opened, and a trap circuit is formed for connection of capacity by means of the capacity between the resonators 21/21' and the case 8.

Title: Camera having distance detector
Inventor: MATSUDA MOTONOBU
IPC: G02B7/28
Filed: 1978-09-16
Abstract: PURPOSE: To obviate mutual affecting of both devices even when the charging power source for capacitor and the charging power source for exposure control circuit are made common by letting charging of the capacitor and exposure control and auto focus control be effected in different times.  
     CONSTITUTION: Before a switch 9 is closed, a transistor 22 is conducting and a capacitor 7 is being charged by a power source 8. When the shutter button is pushed, the switch 9 is closed at the initial stage thereof and transistors 16, 21 conduct and a transistor 22 goes OFF, hence even if the capacitor 7 discharges, charging is no more accomplished. Thereafter, a transistor 26 is conducted with a slight delay by the output of a switching circuit 13, and this causes a transistor 28 to conduct as well to let the capacitor 7 discharge, by which a light emitting diode 4 is let to emit light and distance measurement accomplished. When the shutter button is advanced further, a switch 12 opens and charging to the capacitor 11 through a photoelectric element 10 begins and exposure controlling is accomplished.

Title: Power amplifier
Inventor: YOKOYAMA KENJI
IPC: H03F1/02
Filed: 1977-09-22
Abstract: PURPOSE:To obtain an A-class amplifier featuring a low power loss in the transistor as well as the reduced distortion, by setting the power voltage to be supplied to the power amplifying transistor to such level that is obtained by applying the constant voltage to the voltage which is proportional to the input signal. CONSTITUTION:The input signal voltage is referred to as ei, the gain of amplifier 2 is A1, the gain of power supply amplifier 8 is A2, and the generation voltage of power supply 9 and 10 are E1 and E2 respectively. Thus, the signal voltage of output terminal 6 becomes nearly to A1ei, and the voltage amplified through amplifier 8 is A2ei. If E1=E2=E and A1=A2 are satisfied, collector emitter voltage VCE1=VCE2=A2ei+E1-A1ei=E is obtained. Therefore, generation voltage E of supply 9 and 10 suffices with the minimum collector-emitter voltage necessary for operation of Tr4 and 5. And a constant minimum necessary amount is secured regardless of the input signals, and thus the power loss can be minimized even for a A-class amplifier.

Title: Horizontal deflecting circuit
Inventor: SHINDO SABURO
IPC: H04N3/185
Filed: 1989-05-08
Abstract: PURPOSE:To keep the DC high voltage value approximately at a fixed level and to always attain the equal DC regulation tasks by generating the high voltage with the use of a pulse synchronizing with the higher one of frequencies of two horizontal synchronizing signals even when either one of both synchronous signals is inputted when a deflecting scan is carried out with the use of those two horizontal synchronizing signals of different frequencies. CONSTITUTION:When a horizontal synchronizing signal H-SYNC is inputted to a horizontal oscillation circuit 1, a waveform is produced synchronously with the signal H-SYNC and shaped with the amplification. Then a tooth-shaped current is produced by the switching action of a transistor of horizontal output circuit 3. The tooth-shaped current is supplied to the horizontal deflecting coil of a deflecting yoke 13 to allow an electronic beam to execute the horizontal deflection. On the other hand, the signal H-SYNC is inputted to a deciding circuit 9 for the decision of a horizontal synchronizing signal used for the normal scan or the double scan. Based on this deciding result, a selection circuit 11 is switched. Thus a signal having a double frequency converted by a multiplication circuit 10 is selected in a normal scan mode. Meanwhile a horizontal signal for the double scan is applied as it is.

Abstract: PURPOSE:To improve the universality of a magnetic disk device by enabling the appropriate signal format of output data to be selected corresponding to the constitution of a host device by switching the setting of a conversion circuit by a control means. CONSTITUTION:Recording information on a magnetic disk 11 is inputted to a variable frequency oscillator VFO16 via a magnetic head 12, a read amplifier 14, and a pulse detector 15. The VFO16 oscillates a square wave following the fluctuation of read data due to the fluctuation of the rotating speed of the disk 11, and forms an output signal synchronizing with the wave, and sends it to the conversion circuit 17. In the circuit 17, a read clock is inverted, and is frequency-divided to a double frequency by a frequency divider 23, and is converted to a window signal, and also, the read data is converted to the read data with narrow width via the output of a monostable multivibrator 22 and an AND gate 21. By setting a switch 18 appropriately, the output data with a format suitable for the disk controller of the host device is transferred via an output driver 19.
