Filed: 1983-08-08
Abstract: PURPOSE:To enable the number of members to be reduced by providing a detecting means for detecting the displacement of extension and contraction. CONSTITUTION:A detecting means A is constituted from a magnet 9 provided on the lower end of a cover 5, and a magnetism responsive element 10 held by a support member 11 provided on the outer periphery of the lower end of a cylinder 1. The magnetism responsive element 10 is connected to a control circuit disposed on the outside of a hydraulic buffer. When the magnet 9 is lifted by at least a set distance h so that said element 10 is not affected by magnetic flux, the signal showing such a condition is sent to the input of a control circuit. When the magnet 9 is lowered within the distance h so that said element 10 is affected by the magnetic flux, the signal telling that condition is sent to the input of the control circuit.

The DC voltage of rectifier circuit 13 is supplied to the heater of pickup tube 10 and full load 8 from cable 2 via relay 12 to actuate camera 1. When relay 12 has the adverse action, only the pre-heating voltage of the heater of tube 10 is supplied from constant voltage circuit 9 to secure the pre-heating state for camera 1. On the other hand, the signals from antenna 6 and converter 16 are switched via channel selection switches 21, 23 and 25 within receiver 5. Relay driving circuit 15 operates only when switch 21 is on to receive the image of camera 1.

Title: Magnetoresistance effect element
Inventor: HAYAKAWA MASAMICHI
IPC: G01D5/245
Filed: 1985-07-01
Abstract: PURPOSE:To obtain a magnetoresistance effect element which can be incorporated even with a small gap, by connecting two magnetoelectric elements together and by juxtaposing the same on a plane perpendicular to the direction of variation in a magnetic flux density. CONSTITUTION:Magnetoelectric elements 11 and 12 are connected to terminals 16-18 by conductor members 14 and 15 and disposed, in the vicinity of polar teeth 81 and 91, on a plane (containing an axis 7) perpendicular to the direction of variation in the magnetic flux density of a rotor 6 of a stepping motor 2, together with a substrate 13. The elements 11, 12 and series resistances 20, 21 form a bridge circuit, which is connected to a power source 22 and an earth and joins the terminals 17, 18 to a differential amplifier 23. Magnetic disks 8 and 9 with a permanent magnet 10 held between are combined in such a manner that the phases of the magnetic teeth 81 and 91 thereof are slided by a half pitch from each other. When a coil 5 is electrified, the rotor 6 rotates at a prescribed speed, and the differential amplifier 23 outputs sinewave signals, which can be used as informations on rotational positions. According to this constitution, the magnetoelectric elements do not correspond directly to the pitch of variation in the magnetic flux density of an object to be detected, and therefore they can be used for all objects to be detected. In addition, a resolution is improved, since there is no slippage of phase between the magnetoelectric elements.

Title: Solder for semiconductor
Inventor: NAKAMURA KISAKU
IPC: H01L21/58
Filed: 1978-11-25
Abstract: PURPOSE: To obtain a solder for semiconductor having a high reliability, by adding a fixed amount of Ca into a solder containing In or Pd and Sn as a main component.  
     CONSTITUTION: Ca is added into a solder base material of Pd-Sn alloy, Pd-In alloy, et.c, in the concentration of 50W300ppm. In the concentration less than  50ppm, the solder is easily oxidized and the mechanical strength is not improved,  and in more than 300ppm, the extensibility becomes lower and a strain stress  caused by the difference of thermal expansibilities between the base plate and the  semiconductor chip is not relaxed sufficiently. Further, the excessive mechanical  strength causes a crack on the chip. As the solder has an excellent anti-thermal  wearing, absorbability of strain stress and anti-oxidizability, and also it does not  cause crack on the chip of breaking the junction part, highly reliable junction is  obtained with this solder.

Title: Microstrip antenna unit
Inventor: MAIKURU EI WAISU
IPC: H01Q1/38
Filed: 1983-08-11
Abstract: A microcrisp antenna system having one or more conductively isolated resonantly dimensioned radiator structures disposed less than about one-tenth wavelength above a ground plane is nonconductively coupled to an intermediate layer of microcrip feedline structure. The microstrip feedline structure includes various microstrip transmission line segments fed with reference to the ground plane and including predetermined coupling locations positioned an odd integer number of one-fourth wavelength(s) from an effective r.f. short circuit to the underlying ground plane. Such coupling locations are also disposed proximate a predetermined corresponding feedpoint region of the radiating structure such that electromagnetic fields concentrated at the coupling location operate to nonconductively couple r.f. energy to/from the radiator structure from/to the feedline structure. The coupling location is preferably disposed at a widened and relatively lowered r.f. impedance coupling tab segment of the transmission line having a width dimension which is sufficient to provide matched impedance coupling to the corresponding feedpoint region but which is also substantially less than the dimension of the radiator structure transverse to its resonant dimension. The effective r.f. short circuit may be provided by an actual conductive connection to the underlying reference surface or by an r.f. open circuit termination located an additional one-fourth wavelength therefrom along the feedline structure.

Abstract: PROBLEM TO BE SOLVED: To easily recognize the presence of a magnetic card even when the dark color side of the card is turned upward in a dark place, by forming a luminous display part on the dark color side of the card by means of the luminous ink. SOLUTION: The necessary items consisting of words including 'parking ticket', etc., are shown on the surface side of a magnetic card 1.
