Title: Feed device of magnetic head
Inventor: ISHIKAWA SHIGEKI
IPC: G11B19/02
Filed: 1984-02-03
Abstract: PURPOSE:To suppress power consumption at a low level and to reduce heat generation of a head feed motor to expand the life of a device by providing the device with a control means for stopping the supply of exciting current to the head feed motor. CONSTITUTION:A carriage 9 to be moved up to a required position of a magnetic disc after loading the magnetic head 1 is moved by a carriage pulse motor 10 through a lead screw. The motor 10 and a disc motor 11 are driven by a motor driver 12, which is connected to a CPU8 through a logic circuit 7. Exciting coils L1, L2 in the motor 10 are excited independently by circuits Ci1, Ci2 having the same constitution. For instance, signals having low and high potential levels or signals having reversed potential levels are supplied to the input terminals L1, L2 of the circuit Ci1 respectively, so that constant positive or negative excitation is generated in the coil L1 independently of the variation of the output voltage of a battery B1. Thus, power consumption can be saved and the heat generation of the head carrying motor can be suppressed.

Abstract: PURPOSE:To facilitate the connecting operation and save the labor by inserting press-type contact pieces of each circuit element into a connecting base body for contact with a conductor of the connecting base body so as to connect circuit elements to each other. CONSTITUTION:To interconnect elements 3A-3D via a connecting base body 2, each press-type contact piece 31 is inserted into the connecting base body 2 through a covering 22. The base body 2 and a circuit element 3 are aligned with each other so that a conductor 21 fits into a groove 32 in the contact piece 31. In a particular example given here, the distance between the lower edges of inserting portions 33 is equal to the width of a protrusion 23, and thus the lower edges of the inserting portions 33 can be aligned with the side edges of the protrusion 23 to achieve proper positioning. After alignment has been made, the contact piece 31 is inserted into the base body 2 to fit the conductor 21 into the groove 32, allowing the conductor 21 to be in contact with both sides of the groove 32. As a result, the circuit element is connected to the conductor 21. The other circuit elements 36 are also connected to the conductor 21 in the same way. This results in the elements 3 being interconnected via the conductor 21 of the base body 2.

Abstract: PURPOSE:To improve the recording and reproducing quality of a sound signal of a VTR by recording a video signal and a sound signal applied with code modulation by frequency multiplex on the identical track, separating the frequency of the video signal from that of the code modulated sound signal at reproduction and demodulating respectively the signals. CONSTITUTION:A luminance signal frequency-modulated, a chrominance carrier signal converted into a low frequency and the code modulated sound signal are inputted to a synthesizer 15 in the form that they occupy individual band respectively. Each signal subject to frequency multiplex at the synthesizer 15 is given to a rotary head 17 via a recording amplifier 16 and recorded on a video track on a magnetic tape 18. A signal recorded on the magnetic tape 18 is picked up by the rotary head 17 of the reproducing system, amplified at a head amplifier 19, and then given to filter groups 20, 23, 27 for frequency separation. The luminance signal being an output of a low pass filter 22 and the chrominance carrier signal being an output of a band pass filter 25 are mixed to form a color video signal. The signal obtained by the high pass filter (HPF)27 is restored into the sound signal and outputted to a terminal 30.

Title: Radio receiver
Inventor: SATOU SADAICHI
IPC: H04B7/15
Filed: 1982-02-09
Abstract: PURPOSE:To prevent the generation of a noise and the breaking of the starting part of a signal, by providing a gate and a signal delay device, and cutting off an input signal through the gate in correspondence to the interruption period of a transmitted radio wave from an opposite station and allowing the signal delay device to have two kind of the extents of delay. CONSTITUTION:A signal from an input terminal 1 is supplied to a low-frequency amplifier 8 through an intermediate frequency amplifier 4, signal detector 5, signal delay device 6, and gate 7. The output of the detector 5, on the other hand, is connected to a filter 9, noise amplifier 10, and noise detector 11. When the transmitted radio wave arrives, the noise detector generates no output, so the gate is opened and the delay device 6 outputs the input signal with delay by the 1st extent of delay (corresponding to the time between the interruption of the transmitted radio wave from the opposite station and the closure of the gate 7.) Once the interruption of the transmitted radio wave is detected by the noise detector 11, the gate 7 is closed and the delay device 6 is set to the 2nd extent of delay (corresponding to the time from the restarting of transmission from the opposite station to the opening of the gate).

Abstract: PURPOSE:To prevent transfer defects, carrying detects, etc., by providing a freely rotatable conductive roller slightly apart from an image carrier on the transfer material entrance side of the space between a transfer charger and the image carrier and applying a bias voltage having the same polarity as a transfer power source to this roller. CONSTITUTION:A transfer paper 2 is carried to a transfer region along a guide plate 13; and since the bias of a rollor 3 is zero potential before the transfer paper 2 reaches the roller 3 provided in the space between a photosensitive drum 1 and a transfer charger 10, a floating toner and a slight toner stuck onto the photosensitive drum 1 are prevented from being stuck to the roller to generate the dirt on the rear face. A positive DC bias voltage having the same polarity as a transfer power source 12 is applied to the roller 3 just before the transfer paper 2 enters into the transfer region; and thus, the generation of the transfer defect is prevented especially at a high humidity, and the generation of the carrying defect is prevented.

IPC: F04D1/12
Filed: 1989-02-01
Abstract: PURPOSE: To obtain a suction cycle heat pump having a rotary assembly in which the structure is simplified by feeding volatile components in unevaporative state to a storage tank while traversing a heat exchanging plane unit radially outward and returning a part thereof back to the storage tank while bypassing a condenser. CONSTITUTION: High temperature flue gas from a combustor 12 flows over the outer surface of a generator 14 and discharged through an annular groove 15 after thermal conduction. Vapor of volatile components, i.e., gaseous VVC, flows over a plate radially outward to absorb heat. A mixture flows through a solution heat exchanger 16 and filtered through a passage 20 and a stationary pipe 21 before being loaded onto the plane 22 of a suction disc 22 adjacent to the axis thereof. VVC generated on the inner surface of a pan 14 is condensed on the plane 23 of a condenser disc and collected from a trough 26 at a stationary pipe 26 before being fed into a rotary header ring. The VVC flows through a pipe 29 and sprayed radially inward into an elliptical pipe 31.  A part of LVC evaporates from the inner surface of the pipe 31 to form VVC and the remaining volatile components is returned back to the pipe 31.
