Title: Relief valve
Inventor: MUKUMOTO EIICHI
IPC: B30B15/16
Filed: 1995-01-31
Abstract: PURPOSE: To provide a relief valve in which a difference between a dynamic pressure set pressure and a static pressure set pressure for a relief pressure and dispersion of them can be reduced. CONSTITUTION: An inner circumference face of a pilot valve element 14, through which a support,27 is passed, is expanded so as to be formed into an auxiliary valve chest 31, in which an auxiliary valve element 32 fitted around the support 27 and a sealing member 29 is arranged, and a gap between an inner circumference face of the auxiliary valve element 32 and the support 27 is sealed by means of the sealing member 29, while the auxiliary valve element 32 is pressed to an auxiliary valve seat 38 formed on the inner circumference face of the pilot valve element 14 by means of an oil pressure working on the auxiliary valve element 32 from a pressure chamber 8 side, and consequently, a gap between the auxiliary valve element 32 and the support 27 is sealed.  The sealing member 29 is prevented from being brought into direct contact with the pilot valve element 14, and the sealing member 29 deformed by an oil pressure causes no resistance against a shift of the pilot valve element 14.

Title: Oil-contained tappet automatically regulating variation of length of movable valve system of internal combustion engine
Inventor: KASUYA YOSHIZOU
IPC: F01L1/24
Filed: 1980-02-08
Abstract: PURPOSE: To make automatic and sure control of contacting of a rod and an oil- contained tappet which are expanded or worn under thermal or other influences during running of an engine, by providing a regulation function for the tappet so as to cover a variation of a length of a push rod.  
     CONSTITUTION: When a push rod in a movable valve system of an internal combustion engine is extended during driving of the engine, a pressure applied on a shock receiver 4 is varied and transmitted to an oil in the oil contained cylinder chamber 9. The varied pressure opens a check valve 34 and is transmitted to an oil in an accumulation chamber 33. The oil pressure is propagated to an oil in a shock absorbing oil chamber 28 through an oil in a fine oil path clearance 27 between a hollow plunger cylinder 10 and a bottomed inner cylinder 12 to expand flexible and elastic partition cylinders 24, 25 externally toward a pressure chamber 19, thereby keeping the shock receiver 4 at a lowered position. An air in the pressure chamber 19 is released into open air from an air port 37. If a clearance of the push rod 5 grows, an elastic spring 36 pushes the hollow plunger cylinder 10 to automatically contact the push rod 5 and the shock receiver 4, thereby automatically regulating the clearance.

Title: Package for semiconductor device
Inventor: OBARA MASANOBU
IPC: H01L23/49
Filed: 1984-01-25
Abstract: PURPOSE:To enable the exfoliation of an outer electrode terminal from an electrode pad to be prevented also from tensile force and bending force by a method wherein the required part of the outer electrode terminal is provided with an absorbtion part that absorbs tensile force or bending force. CONSTITUTION:The required part of the outer electrode terminal 1, such as the neighborhood of the junction plane of an electrode pad 3, is provided with a bent part 1b as the absorption part that absorbs tensile force or bending force, which part 1b is filled with a resin 7 to its upper part. This makes it difficult that the outer electrode terminal 1 comes off, when a tensile force acts on this terminal 1, because of being supported at the burial section of the bent part 1b. On the other hand, even when a bending force acts on the terminal 1, the force does not act on the junction because of absorption of the stress at the bent part 1b; accordingly, a high mechanical strength can be obtained.

Title: Method and instrument for measuring angle in three-dimensional space using laser light beam
Inventor: OCHI TATSUYUKI
IPC: G01C1/00
Filed: 1987-01-26
Abstract: PURPOSE:To easily measure the direction of a measurement point from a reference point in a wide-range three-dimensional space by measuring a difference in detection time among laser light beams which are projected from a laser lighthouse and rotated in mutually opposite directions, and performing arithmetic processing. CONSTITUTION:A laser light beam X emitted by a laser oscillator 30 is expanded by a pentagonal prism 3 and the light beam L1 of a 1st end part passes through a cylindrical concave lens 5 and a beam splitter 6 to become a laser light beam CCW1. The remaining light beam is refracted by a reflecting prism 4 and reflected by a mirror 2 to become a light beam CW1. The laser light beam L2 of a 2nd end part travels straight through the reflecting prism 4 and beam splitter 6 to become a light beam CW2. The remaining light beam passes through the prism 4 and mirror 2 to become a light beam CW2. When a turntable 20 is rotated counterclockwise, the light beams CCW1 and CCW2 rotate in the same direction and the light beams CW1 and CW2 rotate in the opposite directions. The angle of the measurement point to the reference point is calculated from the time difference in detection time between the laser light beams which rotate in the mutually opposite directions.

Filed: 1987-01-26
Abstract: PURPOSE:To shorten a positioning time and to improve the alignment of a semiconductor wafer by moving a light source and a detection part relatively. CONSTITUTION:The light source 6 and detection part 7 are moved properly to form a shadow part behind a target pattern 1a and a detection part 7 detects it.

As the depletion and accumuration of electric charge are performed in the region located very close to the surface of the low resistance region 3', the effect inflicted to the current running to the resistance element region 2 becomes very slight. Accordingly, at the crossing part of the resistance region where crosstalk will be brought about as a problem and the conductive wiring having a large potential amplitude, the charge in wiring configuration, charge in the layout of the resistance element and the like are unnecessitated.

Title: Signal processor
Inventor: HARA YOSHIHIRO
IPC: G06T5/00
Filed: 1992-01-30
Abstract: PURPOSE:To statistically reduce the accumulation of quantizing errors by quantizing the signals obtained by adding a certain constant to plural input signals respectively. CONSTITUTION:The constant adding circuits 19-21 add a certain constant ci to plural input signals ai (i= l, 2...n) respectively. Then the signe1.s (ai+ci) are quantized by the quantizing circuits 22-24. The outputs of these circuits 22-24 are added together by an adder 25 and outputted as an output signal Z. That is, if the signal Z outputs the average large value to the optimum quantized value, each constant ci to be added is set at the proper negative value. Meanwhile each ci is set at the proper negative value with the small value outputted to the optimum quantized value. Thus the average value of the calculation errors can be approximated to 0. As a result, the signal Z is never liable to statistically shift in a single direction to the optimum value.

Abstract: PURPOSE:To obtain a polarizing plate capable of easily improving coloration and contrast of an STN-LCD by forming at least one of the protective films of a polarizer of a plastic film consisting of a triacetyl cellulose having a retardation value in a specific range. CONSTITUTION:At least one of the protective films of the polarizer is formed of the plastic film consisting of the triacetyl cellulose having the retardation value measured by light of a wavelength 590nm within a range from 30 to 60nm. The film consisting of the triacetyl cellulose may be a film consisting of the triacetyl cellulose alone or may be a film consisting of a blend with additives, such as plasticizers, and other polymers. The uniformity of the retardation value within the film plane is lost or the degradation in the surface state by wrinkles is generated if the stretching magnification of the triacetyl cellulose increases and, therefore, the upper limit value of the retardation value is confined preferably to <=70nm, more preferably to <=50nm.
