Title: Photo switch element
Inventor: AOYAMA TSUTOMU
IPC: G02B26/08
Filed: 1979-02-08
Abstract: PURPOSE:To obtain the photo switching element of a small size, less insertion losses and high reliability by providing lens systems in the luminous flux of optical fibers and switching the optical paths of parallel light by the lenses through the use of a transparent dielectric. CONSTITUTION:A lens 26 changes the light of optical fibers 21, 22 to parallel light and a lens 27 focuses this parallel light and enters the same into optical fibers 23, 24. A transparent dielectric 25 having a rhombic bottom surface and a moving device 28 are disposed between the lenses 26, 27. Diagonal lines 29 are moved across the optical paths by the moving device 28 to perform switching of the optical paths. For example, when the dielectric 25, i.e., diagonal lines 29 are in the optical paths, the fibers 21, 24 are connected and when the dielectric 25 is moved to outside the optical path, the light advances rectilinearly and the fibers 21, 23 are connected. Thereby, the photo switching element of a small size, low losses and high reliability may be obtained.

Title: Formation of glass thin film
Inventor: FUKUDA CHIE
IPC: C03B19/14
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce the number of crystals precipitated in a glass thin film and to make the transmission loss of an optical waveguide made from the glass thin film small in a process where fine particulates of glass are deposited on a substrate and are heated, thereby turning the fine particulates of glass to transparent glass to form the glass thin film. SOLUTION: In a glass thin film-forming method, a gaseous starting material consisting essentially of silicon tetrachloride is supplied together with a fuel gas from a flame burner 4 on the substrate 1 arranged onto a turntable 3 in a muffle 6 and the fine particulates 2 of glass are produced by a hydralytic reaction and are deposited, and then, the substrate 1, on which the fine particulates 2 of glass are deposited, is cooled while supplying dried air into the muffle 6. Thereafter, the substrate, on which the fine particulates of glass are deposited, is heated in a heating furnace, thereby making the fine particulates of glass to the transparent glass.

Title: Casting apparatus having boosting cylinder for die clamping cylinder
Inventor: FUJII NORIHISA
IPC: B29C37/00
Filed: 1980-02-08
Abstract: PURPOSE: To secure high-speed die clamping by providing a boosting cylinder which increases the  discharge of a pump between the pump and a die clamping cylinder.   
     CONSTITUTION: A change-over valve 8 is operated to send the pressure oil from a variable displacement type pump 7 which can produce necessary speeds, to the small-diameter side (c) of a  boosting cylinder 9. The boosting cylinder 9 having a fixed boosting ratio discharges the pressure  oil from the large-diameter side (d) and receives the supply from the head side pressure port (a)  of a die clamping cylinder 6, thereby pushing down a die clamping plunger 11. In this case, the  die clamping speed is determined by the discharge of the pump 7. Next, in order to maintain the  die clamping force under high pressure, a change-over valve 12 is operated to send high-pressure  oil from the part (a) of the die clamping cylinder 6. In the case of die opening operation, on the  other hand, a change-over valve 8 is changed over to supply the pressure oil from the support  port (b) of the die clamping cylinder 6, whereby die opening is accomplished. The controlling of  this speed is carried out with the pump, and the oil discharged from above is stored in the side  (d) of the boosting cylinder 9. If the oil to be stored in the side (d) is excessive or short, it is  regulated by operating the change-over valve 13.

IPC: B65H29/62
Filed: 1978-02-07
Abstract: PURPOSE: To perform recovery of two sheets of paper currency effectively and promptly by feeding a first sheet of paper currency to a recovery passage and a second sheet of paper currency to a return passage and by treating the two sheets under an overlapped condition when they are recovered or returned.  
     CONSTITUTION: An overlap passage A receives a first sheet of paper currency so that its sum may be counted, and is fed through a distributing plate 42 to a recovery passage B so that the leading end of the paper currency abuts against a stopper 26 and is stopped. Then, a second sheet of paper currency is subjected to its sum counting operation and is fed from the passage A through the distributing plate 42 to a return passage C so that it is interrupted. When the two sheets of paper currency are approved, the whole passages are reversed so that those two sheets are returned through the plate 42 to the passage A, where they are overlapped. After that, the two sheets are fed to the passage B. When their leading ends abut against the stopper 26, the whole passages are stopped so that the two sheets are pooled until a next sheet is poured. Incidentally, the return of the two sheets is performed under their overlapped condition.

Title: Decoder for facsimile
Inventor: YAMADA TOSHIAKI
IPC: H04N1/419
Filed: 1980-02-09
Abstract: PURPOSE:To operate a decoder quickly by storing decoding information once in a decoding information buffer, decoding during the extension of a signal and extending the signal during decoding. CONSTITUTION:Decoding information buffer 12 and color control circuit are set up between decoding circuit 1 and run generation counter 3. Signal (i) from buffer 12 sets the black/white run length of decoding information on counter 3. Said control circuit 13 gives the color information of a sign which is to be extended at present to data output buffer 6 according to color discriminating signal (i). When output signal (g) outputted when a line synchronous signal is detected from decoding information buffer 2 is entered, signal (i) to make white is outputted. When terminating code TC to encode the line length of 0-63 picture elements is detected, signal (i) which changes color information when output signal (g') is entered is outputted. Thus, the decoder can be operated quickly by decoding during the extension of a signal and extending the signal during decoding.

Title: Contactor
Inventor: MIURA TAKEO
IPC: H01L21/66
Filed: 1991-02-06
Abstract: PURPOSE:To improve the speed of IC setting and removing operations by providing a recessed section for guiding ICs on an IC lifting plate which moves in the vertical direction on the contact block for test board of an IC electrical characteristic testing device. CONSTITUTION:An IC lifting plate 5A provided with a recessed section 10 for guiding the outer periphery of the outside frame of ICs is supported by four shafts 6 with springs 7 put on the shafts 6 and, at the time of setting an IC, the plate 5A goes down and comes into contact with contactors 3. When the force pressing down the IC is released at the time of removing the IC, the plate 5A is brought up by the springs and the IC can be easily removed. Since the recessed section 10 positions the IC and reduces the fitting strength of the IC with the contactors, the IC setting and removing operations can be performed smoothly.
