Title: Optical transmitter and receiver
Inventor: MATSUMOTO YASUSHI
IPC: H04B10/077
Filed: 1983-04-12
Abstract: PURPOSE:To enhance the precision of collision detection by setting the output of a transmitter so that an optical signal level at an optical star coupler input time is constant and detecting the collision in a receiver. CONSTITUTION:When such adjustment is performed that the optical star coupler input level of the optical signal from a transmitter 1, 2a and that from a transmitter 2, 2b are constant, the difference of received optical signal level is reduced to only the variance of branch loss of the optical star coupler. Therefore, the level difference of received optical signal is reduced in this optical transmitter and receiver, and the difference between the integration output for a maximum optical signal level at a time, when collision does not occur, and that for a minimum optical signal level at a time when collision occurs is increased. Thus, a collision detection threshold 13 of an identifier 12 is set easily, and the precision of collision detection is enhanced.

Title: Ball delivery mechanism at time of coin successive input in thin type ball lending machine
Inventor: KOBAYASHI HIDETAKA
IPC: A63F7/02
Filed: 1988-03-17
Abstract: PURPOSE:To cause a necessary time up to a ball lending action completion to two or more more coins to be successively inputted to be very short by equipping a means to control the action frequency of a lent ball counting mechanism with a means to control to wait the ball lending action completion for a unit and to execute an immediate shift to a next unit ball lending action. CONSTITUTION:In parallel to the execution of the first ball lending action, for the control when a coil S is successively inputted, the fact that a following coin S2 exist is confirmed by a forward feed sensor 33, a forward feed solenoid 32 is turned on after waiting for 0.8sec, next, the genuineness and kind of the inputted coin S2 are identified, a branched solenoid 51 is turned on when the coin is proper, and a ball outputting flag is set. While a ball cutting related to a preceding coin S1' is not completed, the flags are successively set in the same number as the number of coins. Meanwhile, when the ball cutting related to the preceding coin S1' is completed and the ball outputting flags is set, a shift to a ball pay-out is executed. For it, the number of proper coins is always counted by a routine different from a ball pay-out routine, and for the counting routine, the shift to the next ball pay-out can be executed as soon as the job of 1 cycle of the ball pay-out routine is completed.

Abstract: PURPOSE:To obtain the filter element having the service life as scheduled without any clogging due to the immersion of a brazing filler metal by using the joining material mixing a brazing filler metal and the metal powder body of higher melting point than that and by joining a metal made filter body and end plate by melting only the brazing filler metal. CONSTITUTION:The joining material 2 mixing a brazing filler metal and nickel powder is sprayed on the end plate 1 of the filter element in a doughnut shape and one end face of a metal made cylindrical filter body 3 is overlapped thereon. A weight 4 is then placed on the other end face of the filter body 3 and inputted into a vacuum furnace and after heating taken out of the furnace and cooled at the room temp. The joining material 2 maintains a comparatively high viscosity without melting the nickel powder with the brazing filler metal only being melted in the furnace. The filter body 3 and end plate 1 are therefore joined without the immersion of the joining material 2 to the filter body. The joining materials 2 is then sprayed on the other end plate 5, the filter body 3 is overlapped upside down, heated inside the vacuum furnace similarly as before with pressing by the weight 4 and cooled at a room temp. after heating.

Title: Characteristic measuring apparatus for reflecting film
Inventor: TACHIKAWA YOSHIHIKO
IPC: G01M11/00
Filed: 1989-03-17
Abstract: PURPOSE:To measure a phase skipping of a reflecting film accurately by making two branched laser beams incident onto a reflecting mirror to be measured having a reflecting film to be measured and a reflecting mirror to detect a phase difference between reflected beams therefrom. CONSTITUTION:Output light of a laser light source 10 is branched in two and light beams 11 and 12 are inputted into a differential type interferometer 14. A reflecting film 151 is formed on the rear of a rear reflecting mirror 15 and a reflection film 161 to be measured on the entire surface of a reflecting mirror 16 and they are separated with a spacer at a specified interval. A phase difference detection means 18 receives the two light beams 11 and 12 from the interferometer 14 to detect an optical path difference. As a course length of the light beams 11 and 12 is the same at the interferometer 14 and members are fixed, a change in an apparent reflection position caused by a phase skipping in the reflecting film 161 can be determined accurately. As the reflecting film 151 is not exposed outside, no phase skipping occurs thereby achieving a higher measuring accuracy of a characteristic of a reflecting film used in a measuring device for length and refractive index from the results.
