Title: Rotary magnetic head drum
Inventor: OUCHI HIDEO
IPC: G11B15/61
Filed: 1985-06-27
Abstract: PURPOSE:To prevent the abrasion of a magnetic head and the damage of a magnetic tape, which occur in an acceleration/deceleration period of a rotary drum, by providing a recessed part which is considered so as to adsorb the magnetic tape by generating a negative pressure in the course of rotation, on the periphery of the outside peripheral side of a magnetic head projecting window, and providing the magnetic head on this recessed part. CONSTITUTION:In a rotary drum 1, a 'recessed part' 12 is provided on the periphery of a projecting window 13 of a magnetic head 11, and when the rotary drum 1 rotates, a general relative air current occurs and a negative pressure part is generated, and a wound and installed magnetic tape 5 is adsorbed to the rotary drum 1. In a part where the adsorption is generated, the magnetic head 11 is installed to a position being lower by hundreds of micron than the outside peripheral surface of the rotary drum 1. In such a way, a floating air- gap of the magnetic head and the magnetic tape of the time of magnetic recording and reproduction can be reduced as the relative speed goes to high, and also an abrasion of the magnetic head of the time of acceleration and deceleration of the rotary drum is suppressed and the damage of the magnetic tape can be prevented.

Filed: 1979-10-27
Abstract: PURPOSE: To take out hydrogen gas and carbon monoxide alone respectively, by dehydrogenating methanol into methyl formate and hydrogen gas, and treating a mixture of methanol and methyl formate with a thermal decomposition catalyst.  
     CONSTITUTION: Methanol is dehydrogenated in the presence of a catalyst, e.g. a copper base catalyst, to give methyl formate and hydrogen gas at a reaction temperature of about 100W400°C and a gas space velocity of about 100W50,000hr -1  and a pressure from about 50kg/cm 2 G to ordinary pressure. The reaction mixture consisting of methanol and methyl formate after separating the gas is treated with a thermal decomposition catalyst to give carbon monoxide. The catalyst consists preferably of active carbon and zeolite. The content of the methyl formate in the mixture is about 10W70wt%, and the temperature is about 200W500°C. The reaction pressure is atmospheric one, and the reaction time is about 50secW5hr. Thus, hydrogen and carbon monoxide are obtained without requiring a separating operation.

Title: Thermal transfer recording medium
Inventor: SUZUKI AKIRA
IPC: B41M5/26
Filed: 1985-06-27
Abstract: PURPOSE:To ensure excellent heat sensitivity and enable a high-density image with excellent gradation properties to be obtained, by incorporating a metallic salt or ester of a lanolin fatty acid into an oil. CONSTITUTION:The oil comprises a metallic salt or ester of a lanolin fatty acid. The metallic salt is poorly compatible with a resin, has favorable dispersion stability, and has excellent wetting property for a colored substance. In addition, the salt is highly compatible with solid components when the latter are melted, thereby reducing the viscosity of the melted material. Accordingly, an ink exudes through a porous resin structure and through a network structure of a gradation-controlling agent according to the magnitude of the heating energy applied to the thermal transfer medium, and is transferred to the surface of a receiving sheet. Therefore, the heating energy used for transfer is controlled to produce excellent gradation properties.

Title: Position detection system
Inventor: NISHIO HITOSHI
IPC: G01S5/08
Filed: 1984-07-09
Abstract: PURPOSE:To allow a moving body to easily recognize its position by detecting a radio wave from a satellite at the moving body and detecting an azimuth angle and an elevation angle where the intensity of the radio wave is maximum, and comparing the relation between an azimuth and an elevation angle observed from the ground to the satellite which are stored previously. CONSTITUTION:The radio wave from the broadcasting satellite is received by an antenna 1 and frequency-converted by an antenna BS converter 2, and a satellite broadcast transmitter receiver 3 demodulates a video signal and an audio signal. An antenna direction controller 4 controls the antenna 1 so that the intensity of the radio wave is maximum, and an angle detector 5 detects the azimuth angle and an elevation angle of the antenna 1. Then, an azimuth angle and an elevation angle detected by an arithmetic control means 7 are compared with stored data 6 on azimuth angles and elevation angles from respective points to the satellite to recognize the position of the moving body. Further, radio wave from two broadcast radio wave transmitting centers may be received to calculate the azimuth angle at which the radio wave intensity is maximum and further increase position detection precision. Thus, the position of the moving body is known accurately through the simple device.

Title: Constant current circuit switching device
Inventor: NAKAMURA HIROYUKI
IPC: H03K17/04

Abstract: PURPOSE:To obtain a voltage waveform of a duty factor the same as that of a modulation signal or close thereto by sending a signal to a base of a transistor(TR) switching a drive current to a constant current drive body receiving a current from a current mirror circuit via a circuit having a storage effect of minority carrier. CONSTITUTION:When a modulation drive signal VD reaches a high level, an inverter 5 interrupts a TR 6, a collector potential of a TR 3 receiving a 2nd constant current is fluctuated up to a potential at which TRs 7, 8 are operated from a saturation voltage of the TR 6 by changing the charging of the parasitic capacitance 16 thereby bringing the interrupt state of the TR 8 quickly to the saturation state and turning of a semiconductor laser 12. When the signal VD changes to a low level, the inverter 5 brings the interrupt state of the TR 6 quickly to the saturation state, brings the TR 7 from the active state into the interrupt state and brings the TR 8 from the saturation state to the interrupt state respectively thereby turning on a laser 12. Thus, the same time delay is caused at on/off state of the laser output.
