Title: Hydraulic controller for regeneration and preferential use
Inventor: NAKAGOME YUKINAO
IPC: F15B11/024
Filed: 1985-04-15
Abstract: PURPOSE:To reduce the speed change of the both actuators by varying the regeneration quantity of one actuator in proportion to the operation quantity of the other actuator, in the captioned apparatus for a power shovel for driving a plurality of actuators by one pump. CONSTITUTION:A spool 15 is installed into the body 10 of a selector valve (b) for controlling one actuator (s), and a regeneration flow passage 32, back- pressure valve 24, and a check valve 25 are installed into the spool 15. Therefore, when the actuators (m) and (s) are operated at a same time, the pilot pressure of a pilot selector valve (a) for controlling the other actuator (m) acts into the spring chamber 27 of the back pressure valve 24, and since the pilot pressure varies according to the operation input quantity of one actuator (m), the regeneration quantity of the other actuator (s) varies in proportion to the operation quantity of the actuator (m). Therefore, the speed variation of the regeneration actuators (m) and (s) can be reduced.

IPC: F16K1/226
Filed: 1978-06-30
Abstract: PURPOSE: To improve the sealability of a butterfly valve in a passage having large temperature variation range by so forming the seat of the valve that the seat bent due to thermal expansion enhances the surface pressure between the seat and the disc of the valve.  
     CONSTITUTION: The inner peripheral portion 6 of the seat 4 fixed onto the inner peripheral wall of a valve box 1 is radially inwardly projected in L shape in cross section in a butterfly valve, and the inner peripheral wall 7 of the seat 4 is formed in taper shape. The seat is so formed that the vertical line Q drawn from the bent fulcrum P of the seat 4 toward the outer peripheral wall 11 of a disc 10 making close contact with the seat 4 may pass the interior of the inner peripheral portion 6 of the seat 4. When the seat 4 is bent due to the thermal expansion, the seat 4 bites at the end 28 or projection 8 thereof the outer peripheral wall 11 of the disc 10 to thereby enhance the sealing effect therebetween. The back pressure of the high pressure fluid to the projection 8 or cutout portion 9 of the seat 4 also enhances the surface pressure between the seat 4 and the disc 10 to thereby improve the sealabilty of the valve.

Title: Manufacture of semiconductor device
Inventor: OKETA TATSUO
IPC: H01L21/52
Filed: 1980-06-16
Abstract: PURPOSE:To improve the adhesivity between an element and a carrying table by stopping frictional vibraion based on a detected information regarding a void generated in a wax material. CONSTITUTION:An element 3 is placed on a carrying table 1 of a lead frame 4 through a wax material 2. While the carrying table 1 is heated, the element 3 is subjected to a frictional vibration so that the wax may be melted thereby making the alloy wet on the interface. Under such a condition, an X ray flaw detector 5 is used to project an image the transmission through the void 6 generated in the wax material thereby detecting the quantity of the void in an area measurably with an analyzer 8. Based on the computation of the detected data, it is so controlled that vibration is continued until the quantity of the void reduces to a fixed value, for example, about 15-20% of the element area and then, is stopped to fix the element. This can improve the mechanical and electrical adhesivity and thus assures a high reliability.

Abstract: PURPOSE:To easily measure the oxygen permeability of a contact lens itself irrespective of a shape of the lens and a base curve by holding hermetically the contact lens therebetween by an elastic ring and a holding ring on the tip part of a probe. CONSTITUTION:A contact lens CL is placed in a holding ring 1f, while positioning it by a curler ring 1g, and by rotating and moving a ring nut 1h, the lens CL is pressed against an O-ring 1e, and in the tip part of a probe 1, the lens CL is held therebetween while holding its airtightness. In such a state, the probe 1 in which the lens CL is installed on the tip part is immersed into a physiological salt solution in a container 2. Subsequently, by switching a four-way valve 12, coupling directly a piping 13 and an oximeter 16, leading directly gaseous nitrogen from a gaseous nitrogen cylinder 14 to the oximeter 16, oxygen concentration in gaseous nitrogen is measured, and it becomes a blank value. Next, the four-way valve 12 is switched, and a carrier gas leading-in path 1a of the probe 1, and a carrier gas leading-out path 1b are connected to the gaseous nitrogen cylinder 14 and the oximeter 16, respectively. Oxygen which transmits through the lens CL is fetched into gaseous nitrogen and by measuring its concentration by the oximeter 16, the permeability of oxygen is derived.

Title: Mos transistor
Inventor: TAKATANI KAZUHIKO
IPC: H01L29/78
Filed: 1990-03-28
Abstract: PURPOSE:To improve a MOS transistor in switching characteristics by a method wherein the transistor is changed in gate length. CONSTITUTION:A gate 2 different from that of a conventional MOS transistor in structure is formed large in gate length near a gate electrode and becomes gradually smaller in gate length as receding from the gate electrode. When an input voltage is applied onto the gate 2 and changed, the gate 2 changes in voltage starting from its part near the electrode due to the resistance and the distributed capacity of the gate 2. As the gate 2 is large in gate length near the electrode, a drain current is small in displacement near the electrode and large at a part distant from the electrode. As the load of an integrated circuit composed of MOS transistors is mainly composed of a capacitive load, the voltage of a drain changes as shown by a solid line. A drain changes in voltage as shown by a dotted line when a gate is short and constant in gate length. Judging from the waveform of a solid line, the solid line indicates that a drain is smaller in voltage change per unit time when a gate of this design is used as compared with a dotted line which indicates that a conventional gate is employed. Therefore, noises due to the change of a drain current can be lessened. A drain voltage can be changed in waveform by changing the gate 2 in gate length or in shape.
