IPC: A63F7/02
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To control the probability of a big hit of each pachinko machine to make a game more enjoyable. SOLUTION: The management computer 30 of this system calculates a rate based on obtained data, and decides a new variation range of probability for each game machine 10. Then information of data on the decided variation range of probability is set in a corresponding game machine 10. And each game machine 10 changes its previous probability of a big hit within the set variation range of probability as time passes. And each game machine 10 decides whether a big hit will be granted or not based on the probability of a big hit at the time when its own game condition is in a prescribed condition.

Title: Method and instrument for measuring resonance frequency of rotating body
Inventor: KURIKI TAKASHI
IPC: G01H13/00
Filed: 1989-11-30
Abstract: PURPOSE:To easily measure the resonance frequency with high accuracy by detecting axis deviation in two axial directions intersecting orthogonally while increasing the rotational speed of the rotary body, and further drawing a Lissajous' waveform on a display monitor. CONSTITUTION:The rotating body 1 is rotated and controlled by a driving device 2. Further, the output signal of a rotational speed sensor 8 is inputted to a signal processing circuit 9, which converts the signal into a frequency signal omega. Further, a resonance frequency calculating circuit 12 calculates resonance frequencies omegax and omegay from measurement results obtained by a circle radius measuring circuit 10 and a frequency measuring circuit 11. Namely, when the frequency omega is increased from 0, the deflection of an (x) and a (y) axis is detected to draw the Lissajous' waveform. This waveform is elliptic, but converged so as to draw a circle when omegay<omega<omegax and again when omega>omegax. Then the rotating direction of the ellipse and circles is inverted every time in passing through omegax or omegay. The radius of the circle drawn when omegay<omega<omegax and the current frequency are measured and the radius of the circle which is approximated when omega>omegax is measured to find the frequencies omegax and omegay.

Title: Manufacture of semiconductor device
Inventor: OKUDA KOJI
IPC: H01L21/205
Filed: 1988-12-12
Abstract: PURPOSE:To enable epitaxial growth of a compound semiconductor which has a greatly different grid constant with few defects on a substrate by growing the epitaxial layer of a compound semiconductor on a buffer layer having a hole pattern. CONSTITUTION:In case of AB-AC3 element, when the layer of composition D located inside from a spinodal line at temperature T1 is grown on a semiconductor substrate 1, phase decompositions occur in a first phase 31 (D1) and a second phase 32 (D2) while keeping the grid matching with the semiconductor substrate 1 and it becomes modulated construction in which square-poll-shaped first phases 31 and second phases 32 are arranged alternately. Hole patterns 4 are formed in a buffer layer 3 consisting of such modulated construction through selective etching by removing, for example, the first phase 31 to some depth. And when a layer whose grid constant is different from those of the semiconductor substrate and the buffer layer 3 is epitaxially grown on the buffer layer 3 having the hole pattern 4, by the existence of this hole pattern 4 the internal stress of the epitaxial layer 2 is dispersed. Accordingly, even with the compound semiconductor in the composition where the substrate and the grid constant become great, good quality of epitaxial layer 2 that the grid defect density is small can be obtained.

Filed: 1987-12-11
Abstract: PURPOSE: To reduce the size by generating vapor of a liquid to be frozen and ejecting the vapor into a refrigerant to generate ultrafine frozen particles thereby reducing loss of refrigerant. CONSTITUTION: A liquid 1 to be frozen is heated until the vapor pressure in an enclosed container 2 is settled at an appropriate level and then a flow control valve 8 is opened and a temperature control means 9 is operated to warm the valve 8 and a reducer 10 up to an appropriate temperature.

IPC: F16L1/024
Filed: 1989-12-05
Abstract: PURPOSE:To adhere a buried pipe with a fitting pipe stopper by bringing a round universal-type shaping tool with numerous thin-plate bodies disposed in the vertically movable state at its periphery, into contact with the bored position of the buried pipe, and forming the bored shape of the buried pipe. CONSTITUTION:Numerous thin plates 17 are fittingly inserted between the medium cylinder body 14 and large cylinder body 16 of a round universal-type shaping tool 12. When the cutting of a buried pipe 3 is completed and a center cutter shaft 6 is lowered, the lower ends of the thin plates 17 touch the outer peripheral edge of the hole 21 of the buried pipe 3 and ascend, and the lower end of the cylindrical thin plate group is formed into the same shape as the peripheral edge of the hole 21. In this state, the thin plate group is fixed at the medium cylinder body 14 by magnetic force and pulled up to the ground. As the lower end of the thin plate 17 is formed in an acute angle, accurate shaping can be performed. After pulling the thin plate group up to the ground, its shape copying is made on a fitting pipe stopper 22. Having the same shape at their contact faces, the fitting pipe stopper 22 and the buried pipe 3 can be adhered, thus preventing water leak and the like effectively.

Filed: 1990-11-21
Abstract: PURPOSE:To obtain a surgical filament having excellent wet combining characteristics and excellent surface lubricity characteristics such as organ transmission properties, etc., by coating the surgical filament with a basic amino acid having a long chain acyl group. CONSTITUTION:A surgical filament having its surface coated with a composition containing at least one kind of N-long chain monoacyl amino acids having a aliphatic acyl group of carbon number 6 to 22 or at least one kind of N-long chain monoacyl amino and having its surface lubricity characteristic improved.

The wet combining characteristic of the surgical filament and the surface lubricity characteristic thereof such as organ transmission properties, etc., are almost the same as those of dry and besides safety of the tool for living tissue is high.
