Title: Control valve unit
Inventor: HASHIMOTO YUTAKA
IPC: F15B13/06
Filed: 1982-05-22
Abstract: PURPOSE:To assure a specified flow rate to the arm by providing a relief valve in the spring chamber located on one side of the flow rate regulating spool shifted by the metering notch pressure differential. CONSTITUTION:When spool 4 moves to the right from the neutral position, the flow volume corresponding to the degree of opening of the metering notch 18a flows to the cylinder port 22a. Cylinder port 22a pressure is applied to spring chamber 19 and the pressure from feed line 14 is applied to action chamber 20, therefore, when metering notch 18a differential pressure increases, flow rate regulation spool 13 moves to the left to bypass the oil from inlet port 12 through the lower center bypass line 9. The bypassing oil increases pressure on relief valve 10, lowering pump delivery rate to the level equivalent to the spool 4 required flow rate + slight relief flow rate.

Title: Thin film magnetic head
Inventor: TOYODA ATSUSHI
IPC: G11B5/31
Filed: 1991-03-26
Abstract: PURPOSE:To improve a recording characteristic by preventing the magnetic saturation of a pole part at the time of recording. CONSTITUTION:A thin wall part which is thinner than the-thickness of the pole part 36 of a lower magnetic layer 14 and the thickness of the maximum thickness part of the lower magnetic layer is formed at the throat height zero position 62 or its vicinity of the lower magnetic layer 14. Through such constitution, when a writing current is made large, the thin wall part is saturated magnetically, and here, since the total amount of magnetic flux to flow in the tip of the pole part is restricted, the so large magnetic flux as to saturate the tip of the pole part does not flow. Accordingly, even if the writing current is made large, a sharp and strong writing magnetic field is generated at a magnetic gap, and writing density can be made high.

Title: Signal reception system
Inventor: FUKUMOTO YOSHIHIRO
IPC: H04B3/54
Filed: 1985-04-24
Abstract: PURPOSE:To attain accurate signal reception by detecting and receiving a signal sent from a sending station as a power signal without a current standing wave phenomenon and a voltage standing wave phenomenon. CONSTITUTION:A sinusoidal wave signal sent from a sending station 6 exists on a distribution line 3 as a standing wave when the signal frequency is high or the length of the distribution line 3 is long. In observing the voltage and current standing waves produced on the distribution line between the sending station 6 and a reception station 4 while neglecting the loss of the distribution line 3, although both the waves are sinusoidal waves but the maximum values are shifted by 1/4 wavelength. That is, the current standing wave ISW is shifted from the voltage standing wave ESW by 1/4 wavelength, and then the standing wave power is obtained as a sum PSW of the power by the standing wave voltage and the power by the standing wave current and is distributed over the entire length of the distribution line 3 at a prescribed level. That is, the power signal is detected at any position of the distribution line 3 independently of the current and voltage. Thus, the reception station 4 can detect and receive surely the signal sent from the sending station 6 independently of the installed position of the reception station 4.

Abstract: PURPOSE:To prevent the generation of a poor conduction between a filament support and wiring patterns, by furnishing the connections of the wiring patterns on a glass base plate and the filament support at the outer side from the portion of applying a fixing frit glass. CONSTITUTION:The positions of conductive frit glasses 6, where island-form patterns 2a and 2b of a wiring pattern 2 formed on a glass base plate 3, and the pawls 4d and 4e of a filament support 4' are connected, are arranged in the outer side from the positions of fixing frit glasses 7 where patterns 2c on the base plate 3,and the fixing parts 4b and 4c of the filament support 4' are connected. Therefore, when the filament 5 is welded to the filament support 4a, or the like, a strong force imposes to the filament support 4a, to float up it from the base plate 3 in some occasion. However, no such a force imposes to the connections of the said island-form patterns 2a, 2b and the pawls 4d, 4e. Therefore, the generation of a poor conduction in the filament circuit from the floating of the filament support 4' can be prevented.

Abstract: PURPOSE:To allow the free change of the diameter of a mask which determines the thin film forming range on a disk substrate of the sputtering device for optical disks from the outside of the chamber of the sputtering device. CONSTITUTION:Plural sheets of plates 41 which are formed to the same shape, have respectively grooves and are so arrayed as to draw a circle with the outside shapes are used as the mask of this sputtering device for optical disks. Projecting parts 44 of a circular ring 43 having projections by as much as the number of the plats 41 are put into the grooves of the respective plates. This circular ring 43 is rotated from the outside and all the plates are simultaneously rotated by the projecting parts, by which the diameter of the circle drawn by plural sheets of the plates is changed and the diameter of the mask is changed.
