Title: Measuring device for inside diameter
Inventor: WATANABE TERUO
IPC: G01B7/06
Filed: 1981-06-19
Abstract: PURPOSE: To measure the inside diameter of an object to be measured accurately and quickly by erecting a positioning member provided with a head of a tapered shape on a stage freely vertically movably.  
     CONSTITUTION: While the inside surface part of an object 26 to be measured is brought into abutment on the tapered surface of a head 27, the object 26 is moved downward against the force of a spring 7, until it abuts on the mounting surface 12 on a stage 3. At this time, contactors 10 can escape in containing  grooves 9 on account of the defromation of a spring 25. When a base plate 14 is moved upward or downward by rotating a handle 18 with stanchions 2 as a  guide it is possible to move the contactors 10 vertically with respect to the  surface 12 of the stage 3. While the two contactors 10 facing each other are  held in abutment on the inside diameter of te object 26, the distance between  the contactors 10 is read with a differential transformer 21 which is a displacement detector, via a measuring element 8 and a holding member 13.

Title: Thermal head
Inventor: SHIROTSUKI YOSHIYUKI
IPC: B41J2/345
Filed: 1982-06-04
Abstract: PURPOSE:To make the temperature distribution of a heat generating part uniform and perform an operation with a high efficiency, by providing a heat generating resistor, separating into a plural number, in the direction of a right angle to the direction in which the electrodes oppose on an insulating substrate and constituting a thermal head. CONSTITUTION:The heat generating resistor 3 of a thermal head is constituted being separated into two parts 3a, 3b. By adopting such a constitution the peak temperature of a heat generating part exists at two places of each middle point of the heat generating resistors 3a, 3b, it results in the trapezoidal temperature distribution of a heat generating surface. By this, the area of the inclined line part P which is surrounded by the curve of the temperature distribution and the line of the minimum temperature T necessary for a color development, i.e., the loss of an electric power decreases. Further, as the maximum temperature (Tmax) of the heat generating part is lowered, the thermal stress which is generated in peripheral materials becomes correspondingly small and the crack caused at the heat generating part is lessened.

Title: Rotary compressor
Inventor: KANAZAWA TAKAKI
IPC: F04B39/02
Filed: 1979-07-28
Abstract: PURPOSE:To enable lubricating oil to be positively and readily supplied to slide portions by utilizing a reciprocating motion of blades for an oiling pump. CONSTITUTION:Rotation of a roller driving shaft 15 makes a roller 16 rotate eccentrically in a cylinder 14 to reciprocate blades 17. This reciprocating motion of the blades 17 produces pumping action in a closed space 20 behind the blades 17 to suck lubricating oil L into the closed space 20 and discharge it to a lubricating path 25. That is, when the blades 17 start to move forward, the closed space 20 is expanded to produce negative pressure so that a free valve 23 moves away from a communicating port 22 to open it and absorb the lubricating oil L into the closed space 20. When the blades 17 then starts to retreat, the lubricating oil L in the closed space 20 is supplied to respective slide portions through lubricating paths 25 positively and readily.

Title: Reference voltage generating circuit
Inventor: ISHIDA KOUJI
IPC: H03F1/00
Filed: 1979-07-27
Abstract: PURPOSE:To prevent right and left stereophonic signals for stereophonic amplifiers from deteriorating in separation by improving circuit characteristics by reducing output impedance as to a reference voltage generating circuit adequate to generate a bias at a circuit connection point between audio amplifiers. CONSTITUTION:Since transistor TR Q12, Q13 are of common emitter single-ended push-pull constitution, output impedance viewed from output terminal VR is equivalent to that of an emitter follower circuit. Namely, it depends upon base resistances R11 and R13 and current amplification factor hFE of TRs and is extremely small. Thus, circuit characteristics are made excellent, and right and left stereophonic signals for stereophonic amplifiers are never caused to deteriorate in separation.

Title: Magnetic head
Inventor: NAGATSUKA SHINTAROU
IPC: G11B5/133
Filed: 1984-05-16
Abstract: PURPOSE:To suppress an erasure magnetic field produced by the adhesion layer of a metallic magnetic material and an oxide magnetic material until it is ignored by optimizing the saturation magnetic flux density of the oxide magnetic material to the coercive force of a magnetic tape. CONSTITUTION:Both flanks of a core made of a metallic magnetic material which is made thin to track width, e.g. ''Sendust(R)'' chip 1 are sandwiched between holders 2a an 2b made of an oxide magnetic material, e.g. ferrite and those members are united together to constitute the magnetic head. The magnetic flux density Bs of the ferrite used for the holders 2a and 2b is so set that Bs approx.<3Hc, where Hc is the coercive force of a magnetic tape on which the magnetic head records a signal. Consequently, the erasure magnetic field generated by the adhesion layer of the chip 1 and holders 2a and 2b is made much less than the coercive force of the magnetic tape until it is ignored and an excellent recording pattern is obtained.
