IPC: G11B5/127
Filed: 1980-02-18
Abstract: PURPOSE:To manufacture a narrow-track magnetic head suitable to long-time VTR, etc., which uses a metallic tape, by composing the butted surface of a magnetic gap by using a single crystal of Fe-Al-Si alloy havig high-magnetic permeability and specific surface azimuth. CONSTITUTION:The magnetic head (where 4 is a winding window and 2 is a supporting body), formed by butting a couple of core bodies 1 mutually with core gap part 3, has the butted surface of the magnetic gap by using a single crystal of Fe- Al-Si having high-magnetic-permeability and surface azimuth of surface (113) [or a surface inclining so that the properties of surface (113) will not be lost]. Because  of the use of said cores, the narrow-track head whose inductance is extremely excellent can be obtained.

Title: Electric cooking stove
Inventor: KOBAYASHI YASUMICHI
IPC: H05B3/76
Filed: 1984-02-03
Abstract: PURPOSE:To improve an accuracy in sensing of temperature by a method wherein an energization for an eddy current type sheath heater is controlled with reference to a result of comparison between an output of a sensor unit for sensing a temperature at a bottom part of a pan and an output from a temperature setting unit in an electric heater provided with a temperature adjusting function. CONSTITUTION:When a temperature of a thermistor TH in a sensor 13 for sensing a temperature of bottom part of a pan is low, a resistance value is high, an electric potential of an input terminal (+) of a comparator 12 becomes higher than that of an input terminal (-), and then an output terminal of the comparator 12 is opened. Due to this fact, an electric current is flowed to the base terminal of a transistor Q through resistors R4 and R5 to turn on the transistor Q, a gate current of a bilateral thyristor SCR is flowed through a resistor 7, the thyristor SCR is turned on and the sheath heater 2 is energized. when a temperature of the thermistor TH is increased, an energization of the sheath heater 2 is stopped through a reversing of the comparator 12. With this arrangement, a sensing accuracy is improved under a sheathing of radiation heat from the sheath heater.

Filed: 1994-02-16
Abstract: PURPOSE:To cause a coupling arm to hardly impede other member and reduce the size of the device by providing a coupling arm to integrally rotate first and second supporting tools. CONSTITUTION:A coupling arm 11 is caused to intercouple first and second supporting plates 3 and 7 in a range between one end side and the other end side in the axial direction of the shaft 2 of the first supporting plate 3, i.e., between a wall surface on the left end side and a wall surface on the right end side, and integrally rotate the first and second supporting plates 3 and 7.

Title: Selection circuit
Inventor: ITOU EIJI
IPC: H03K17/00
Filed: 1979-02-21
Abstract: PURPOSE:To minimize the number of control lines to just one and then secure transmission of the selection switch signal and the display signal, by returning the selection switch signal supplied via the control line to the input via the holding circuit. CONSTITUTION:When non-lock switch 21 is turned on, lamp 35 glows. At the same time, transistor 28 is turned off to turn the output of gate 30 into a low level. While the output of gate 31 forming the FF features a high level to turn transistor 34 on. Accordingly, lamp 35 glows continuously via transistor 34 although switch 21 is turned off, thus indicating that switch 21 has been selected. To release the selection, the reset pulse is applied to gate 32. As a result, only one piece of the control line suffices between terminals 22 and 23.

Title: Manufacture of metallic foil
Inventor: NAKAMURA KAZUO
IPC: B21B27/00
Filed: 1988-02-01
Abstract: PURPOSE:To stably manufacture foil by using work rolls having a specified range of surface roughness each in the final pass and rolling by work rolls having a surface roughness each larger than this in the upstream pass excepting the final pass. CONSTITUTION:In a manufacture of metallic foil, rolling is performed by work rolls having a surface roughness Ra<0.1mum each in the final pass and by work rolls having a surface roughness Ra>=0.1mum each in the upstream passes excepting the final pass. As occasion calls, the rolling is performed by work rolls having a surface roughness each nearly equal to the surface roughness of the foil required in the final pass. Since, in the upstream passes excepting the final pass, the surface roughness of each work roll has a value >=0.1mum, the frictional coefficient between each roll and the foil becomes large. As a result, since the foil is prevented from lateral slip in a rolling process, the manufacture of the foil is stabilized.

Abstract: PURPOSE:To easily enhance sensor sensitivity by taking out the difference between the outputs of respective heating wires when the respective heating wires are separately driven by mutually independent constant current power supplies as sensor output. CONSTITUTION:This gas type angular velocity sensor is constituted so that constant current power supplies E1, E2 are respectively connected to a pair of heating wires F2, R2, which are provided in series, in parallel with the polarities shown by a drawing and the difference between the outputs of the heating wires R1, R2 is taken out as the detection signal of the angular velocity omegaacting on a sensor main body by a differential amplifier AMP. In this case, when each of the constant currents (I1, I2) respectively supplied from the constant current power supplies E1, E2 is set to the same degree as the constant current I supplied from the constant current power supply E in conventional circuit constitution, sensor output X becomes almost twice conventional sensor output X'. Further, the temp. dependence of offset adjustment is eliminated.

Title: Constant voltage circuit
Inventor: INABE YASUNOBU
IPC: G05F3/22
Filed: 1989-01-30
Abstract: PURPOSE:To reduce the number of current routes and to decrease circuit current by connecting a resistor for generating voltage with a positive temperature factor to a PN junction element for generating voltage with a negative temperature factor in series in the same current route. CONSTITUTION:A part consisting of transistors(TRs) Q9, Q10, Q12 and resistors R6, R7 forms current I4 comparatively prevented from being affected by the variation of a constant voltage source VC. The current I4 is supplied to a TR Q11. On the other hand, a part consisting of the TR Q11, Q13 and a resistor R8 generates voltage V2 having a positive temperature factor on both the ends of a resistor R9. At that time, the value of current I5 flowing into the TR Q13 is set up to a value approximate to the current I4. The output voltage of a terminal T2 is V01 = V2 + (base-emitter voltage of TRs Q14, Q15). The base-emitter voltage of the TRs Q14, Q15 has a negative temperature factor. Thereby, the temperature factor can be set up to zero while setting up the voltage 01 to a required value. Thus, the constitution makes it possible to reduce the circuit current.
