Abstract: PURPOSE:To contrive high recording densification by setting a parameter value to be obtained from an angle formed with a tangential line at an apex part of a sliding surface and a tangential line in an end part position and an inflow angle of a recording medium and also tension per unit width of the medium to fall within a prescribed range. CONSTITUTION:The angle formed by the tangential line Ls in the end part position of the sliding surface 3 of a magnetic head 1 and the tangential line Lo in the apex part position forming a magnetic gap 4 is denoted as alpha, and the angle formed by the magnetic tape 2 in its inflow/outflow direction to the sliding surface 3 and the tangential line Lo is denoted as beta, and then the tape tension per unit width of the magnetic tape 2 is denoted as T. The parameter P is specified as P=TXsin(beta-alpha), and this parameter value is constituted to fall within a range from 0.12gf/mm to 0.3gf/mm. The constitution is established by changing the relationship of alpha and beta in order to compensate an increasing amt. of this tension, so that the traveling with the smallest possible space can be maintained. By this method, excellent electromagnetic conversion characteristics at the time of high speed traveling can be maintained, and hence high recording densification can be contrived.

Title: Thin film transistor
Inventor: MATSUZAKI EIJI
IPC: H01L29/78
Filed: 1985-11-22
Abstract: PURPOSE:To enable the FET active matrix with large area to be formed easily by a method wherein the activating energy of conductivity of an a-Si forming a channel is reduced in proportion to the decreasing distance to a gate insulating film. CONSTITUTION:40 SCCM of silane SiH4, 160 SCCM of hydrogen H2 are fed to a glow discharge device subject to high frequency power of 50W and reactive gas pressure of 106.4 Pa to form an a-Si film around 400mum thick. The activating energy of a-Si film to be a channel is changed in the thickness direction to reduce the activating energy on the side of a gate insulating film. In other words, the temperature of substrate forming the a-Si film is changed with time lapse to change the hydrogen content in the a-Si film. Through these procedures, the activating energy of a-Si film can be increased from 0.6eV on the gate insulating film side to 0.8eV on the surface.

Title: Operating controller for refrigerating machine
Inventor: MURAKAMI TAKESHI
IPC: F04B49/06
Filed: 1989-10-05
Abstract: PURPOSE:To shorten the low-frequency start-up period of time for improving the comfort of air conditioning by a method wherein the output voltage vs. output electric current characteristic of an inverter is shifted from an optimum point, where the electric current value becomes minimum, only during low-frequency start-up time period. CONSTITUTION:When a low-frequency command signal is output by a signal output device 51 to output a specified low-frequency for a certain time period after commencement of operation, an output characteristic change device 52 changes the output voltage vs. output electric current characteristic of an inverter 6 so as to shift the electric current value from an optimum value, so that the output electric current is increased from the optimum value, and the increase of the output electric current results in an increase of the heat loss of a compressor 1, causing an increase in the oil temperature. As this increase in the oil temperature accelerates separation of the refrigerant dissolved in the oil, the low-frequency start-up time period required for preventing foaming is shortened, and the normal operation with a high performance quickly takes place. Therefore, the room temperature quickly approaches the set point and the comfort of air conditioning is improved.

Title: Oscillation circuit
Inventor: AOKI KAZUO
IPC: H03L3/00
Filed: 1986-10-31
Abstract: PURPOSE:To surely stop oscillations synchronously with a control signal by adding a P channel MOS transistor which is connected between two terminals of a resonance circuit and has gate input of a control signal for start/stop of oscillations to a position between a drain and a source. CONSTITUTION:A control signal is set at an L level in order to stop oscillations of an oscillation circuit. The output of a two-input NAND gate 9 forming an amplifying circuit 1 is fixed at an H level. The electric charge stored in a capacitor 8 is discharged in a short time through an output transistor TR set at the H side of the gate 9. Under such conditions, a P channel MOS TR 10 connected to both ends of a resonance circuit 5 is turned on and therefore the electric charge stored in a capacitor 7 and an inductance 6 are also discharged in a short time through the TR 10 and the output TR set at the H side of the gate 9. As a result, the oscillations of this circuit are surely stopped synchronously with the control signal.
