Title: Terminal seal portion of spark plug
Inventor: YOSHIDA MITSUTAKA
IPC: H01T13/20
Filed: 1990-06-12
Abstract: PURPOSE:To improve the mechanical strength of a terminal against external stress by forming the peripheral face of head of the terminal at a seal portion in a roulette face tilted at a specified angle to a direction orthogonal to an axial line. CONSTITUTION:A roulette face by mutually crossed carved-lines 10 is formed on the peripheral face of a head portion 6 connected to a glass seal portion 9 at the head of a terminal 5, and a pitch P between the mutually paralleled carved-lines 10 is equalized to a size of 0.9mm. And the tilt angle theta1 of each of the carved-lines 10 is equalized to an angle of 15 deg. to 25 deg. against a face orthogonal to an axial line. The smaller this tilt angle theta1 may be, the smaller the number of threads of the carved-lines in the circumferential direction of the head portion may be so as to decrease internal stress in the circumferential direction. The more the tilt angle in this connection may be, the more a tilt close to a screw or the internal stress may be increased. The tilt angle exceeding 25 deg. causes the internal stress to be remarkably increased, and the tilt angle of less then 15 deg. causes the cross-sectional shape of the terminal not to retain its round shape so that stable sealing of the terminal can not be retained in fittingly attaching the terminal to a plug.

Title: Dc-dc converter type power supply circuit
Inventor: MINOWA MASAHIRO
IPC: H02M3/155
Filed: 1981-09-25
Abstract: PURPOSE:To elevate line voltage with the rise of an ambient temperature by connecting the parallel circuit of a thermistor and a resistor and a series circuit with a constant-voltage element between a connecting section with a power supply at the secondary side of a diode and the base of a controlling transistor. CONSTITUTION:When the potential of output rises, the rise is transmitted to the base of the controlling transistor 4 and the transistor is at ON, a feed transistor 3 is at OFF, and oscillation is stopped temporarily, thus stopping the supply of power to output. When the potential of output drops, on the other hand, oscillation is strengthened. The potential hardly has relation to the variation of battery 1, and determined by voltage generated in the series circuit of the Zener diode 11 and the resistor means 15. When the ambient temperature rises, voltage generated at a terminal 16 at the secondary side also drops because the resistance value of the thermistor 12 drops and voltage Vc drops while being also related to a resistor 17. Accordingly, voltage is changed positively by temperature, and characteristics proper to a thermal printer can be given.

Title: Method of measuring threshold current of semiconductor laser and device thereor
Inventor: SEKIDO KENJI
IPC: H01S5/068
Filed: 1980-10-29
Abstract: PURPOSE:To contrive a simple method of measuring a threshold value and to exactly measure a threshold value by utilizing the fact that the luminous modulation cut off frequency of a semiconductor laser is the difference between the spontaneous emission emitting light and the laser emitting light. CONSTITUTION:Bias current is supplied to a semiconductor laser 1 from the first bias power source 2 through a DC ammeter 3 and a choke coil 4. Furthermore, a modulation signal having higher oscillation frequency than the modulation cut off frequency of the spontaneous emission LED light emitting of the laser 1 and that lower than the modulation cut off frequency of the laser emitting light is generated from a modulation signal power source 5 to superimpose the modulation signal on the bias current of the laser 1 through a capacitor 6. The light output from the laser 1 is received by a light sensitive photo diode 7 and a suitable reverse bias is applied to the light sensitive photo deiode 7 by the second bias current source 10 to supervise a modulated component detected by a detector 12 by a voltmeter 13. And the current of the laser 1 is gradually increased by the power source 2 and a current value detecting or distinguishing a modulation signal component at the light output is measured to use the current value as a threshold value.

Filed: 1984-07-25
Abstract: PURPOSE:To enable the effective formation of minute mask patterns by arranging a step ped part of the predetermined width and depth in the circumferential part of a semiconductor substrate. CONSTITUTION:Resist is spread over a surface of the semiconductor crystal substrate 1 which is selected out of the group consisting of Si, Ge, VI-semiconductor, III-V compound semiconductor and mixed crystal thereof, and II-VI compound semiconductor and mixed crystal thereof.
