Title: Waveform shaping circuit
Inventor: MIYAZAKI MASAAKI
IPC: H03K5/08
Filed: 1985-04-09
Abstract: PURPOSE:To obtain a waveform shaping circuit which is inexpensive, hardly affected by the ambient temperature, and stably operates even to a noise, by using the threshold voltage of a digital IC as a comparison level and constituting an interface circuit by using a low-pass filter, voltage limiter, and voltage divider. CONSTITUTION:When a switch 101 is opened, the voltage at a point B is limited to 5.6V by a diode 6 and the voltage at the output point C of a voltage divider 104 becomes 3.8V. Since the voltage 3.8V is higher than the threshold voltage of about 1.2V of a microcomputer 10, the computer 10 detects the input state as 'Hight'. Moreover, since all the voltages at the points A, B, and C are zero V which is lower than the threshold voltage, the input state is detected as 'Low'. Since the threshold voltage of the microcomputer 10 formed of an NMOS is hardly affected by the ambient temperature, the voltage is stable and, since the voltage at the point B is limited to a range of -0.6-5.6V by a low-pass filter 102 and voltage limiter 103, the voltage at the point C becomes -0.4-3.8V and the microcomputer 10 stably operates.

Abstract: PURPOSE:To miniaturize a lead part and to make it possible to achieve further high integration of ICs and the like without the decrease in insulation between leads due to time deterioration under an electric field by using a specified metal foil for a metal layer, and performing electroplating for a tin or solder layer. CONSTITUTION:A copper foil (oxygen free copper foil whose surface is roughened at a low degree) which is obtained by roughening the surface of an oxygen free copper foil in a low degree is used for a metal layer which is bonded on the insulating film of a tape carrier for TAB. Tin or solder electroplating is used for coating the metal layer with low-melting-point metal after the formation of a pattern. The low-surface- roughness oxygen free copper foil has the surface roughness wherein the average depth Ra of the surface in contact with a bonding agent does not exceed 0.4mum. The low-surface-roughness oxygen free copper foil which undergoes zinc chromate treatment is bonded on the insulating film. A copper layer is formed on the insulating film 1. The copper layer comprises a lead part 2 and a temporary linking part 2a. After the formation of the pattern, the temporary linking part 2a is connected to the terminal of a plating power supply, and electroplating is performed. The part of a blanking part 2b is blanked and removed with a metal mold, and the TAB tape carrier is obtained.

Title: Controller for game machine
Inventor: HOYA MAKOTO
IPC: A63F7/02
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a controller for game machine by which the value of a counter can be maintained at values within an original updating range even when the value of that counter is repeatedly updated for the remaining time of interrupting processing. SOLUTION: When Low is outputted from an OR circuit 39 at every 2 ms (K), Hi is inputted to the PR terminal of a D flip-flop 42 (L). Since Vcc is inputted to a CLR terminal, an operational code fetch signal is outputted from a CPU 11 and when the output of a LIR terminal falls from Hi to Low, the input to the CK terminal of the D flip-flop 42 rises from Low to Hi (M). Then, Low output inputted to a D terminal (K) is outputted from a Q terminal to a URES terminal (N) and user reset interruption occurs at the timing of operational code fetch. Therefore, since reset interrupting processing is not executed during the execution of a write instruction, even when the value of an initial value counter is repeatedly updated during the remaining time of reset interrupting processing, that value can be maintained at values within the original updating range.

Title: Optical element and optical information processor using the element and production of optical element
Inventor: YAMAMOTO HIROAKI
IPC: G11B7/135
Filed: 1993-04-05
Abstract: PURPOSE:To provide the polarization separating element which can be produced by the simple process for production without requiring mask alignment and has high reliability, good productivity and good extinction ratio. CONSTITUTION:Proton exchange layers 21 are periodically formed on a lithium niobate substrate 20 of an x face and further, grooves 24 are formed by selective etching using hydrofluoric acid. The light transmitted through the proton exchange layers 21 and grooves 24 of the polarization separating element produced in such a manner generates a deviation in phases with the light which does not transmit these parts. A phase advance takes place in both the proton exchange layers 21 and the grooves 24 when ordinary light is made incident, but a phase delay takes place in the proton exchange layers 21 and the phase advance in the grooves 24, thus acting in the directions where the deviations in the phases are offset with each other if extraordinary light is made incident. The polarization separating element which diffracts the ordinary light and does not diffract the extraordinary light is obtd. by adequately selecting the depth of the proton exchange layers 21 and the grooves 24.

Abstract: PURPOSE:To realize a cross connector with less buffer quantity by providing a variable delay means which calculates a required delay time according to the statistical distribution while availing the arrival of a detected packet itself of an opportunity and produces the calculated delay time to the system. CONSTITUTION:In the case of multiplexing a packet 400 sent from plural user equipments, the position to be multiplexed is allocated to each packet dynamically, that is, at a random delay according to a statistic rule.

Moreover, the control section 403 generates a control data as to how much delay is to be provided according to the statistic distribution to each input packet based on a slot allocated to a just preceding packet. Thus, the periodicity in terms of the packet multiplex level is relieved and the cross connector is realized with less buffer quantity.
