Title: Multiplexer circuit
Inventor: HAYASE TSUTOMU
IPC: H03K17/00
Filed: 1990-08-22
Abstract: PURPOSE:To prevent production of an undesired spike waveform by providing a circuit outputting a signal of a same waveform as that of a multiplex signal inputted when an output signal of a logic circuit is logical 1 to the multiplexer circuit. CONSTITUTION:An input section for direct input of a decode signal 121, an input section receiving the decode signal 121 via a NOT gate 41 and a delay element 51 and a 2-input OR circuit form a directive differentiating circuit outputting a waveform resulting from differentiating the input signal only when the input signal changes from 1 to 0. In this case, even when the input state of a D-latch 8 changes for a preset time when a signal 0 is fed to a control terminal G of the D-latch 8, an output signal 171 is unchanged. Moreover, in other cases, the output signal 171 is changed corresponding to the signal inputted to an input terminal D of the D-latch 8. Thus, the production of an undesired spike waveform is prevented.

Title: Method for developing resist
Inventor: MUTO AKIRA
IPC: G03F7/30
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To make a pattern width at the central part of a wafer selectively thinned through device adjustment only when the pattern width in the central part becomes thicker, by alternately setting the wafer in stationary states and rotating states a plurality of times, while the wafer is held at a fixed inclined angle and a developing solution supplied to the wafer is maintained on the wafer. SOLUTION: Paddle development is performed while a wafer is inclined at an angle at which a paddle-formed solution does not drop down from the wafer from a horizontal state. The paddle development is performed by supplying the solution to a thickness of about 2 mm and intermittently rotating the wafer, by repeating six times, for example, slow rotation at 60 deg. for one second and resting for 9-second. When the wafer is inclined, the solution is collected to the lowest end section of the wafer while resting for 9-second. During the slow rotation at 60 deg. for the next one second, however, the lowest end section moves upward and the developing solution flows to the new lowest end section and stabilized in the section during resting for the next 9-second.  When this intermittent rotation is repeated 6 times, the developing rate becomes faster, because the developing solution is more scattered in the central part than in the outer peripheral section at every rotation.

Title: Call processing system for incoming call
Inventor: FURUKAWA HISAO
IPC: H04M3/50
Filed: 1993-09-06
Abstract: PURPOSE:To make a caller who receives no answer for a long time because of a called subsriber busy state or called subscriber absence select a call processing system through announcement. CONSTITUTION:When a CLG 1 originates and an LC 11 terminals, the LC 11 sends the dial signal from the CLG 1 to a CPU 9, which recognizes whether or not it is an incoming call to a CLD 2 and checks its free state. When the CLD 2 is free, the CPU 9 sends ringing to the CLD 2. When the CLD 2 is busy, the CPU 9 controls an SW 8 to connect the CLG 1 to an ANM 5 through the LC 11. The ANM 5 after automatically answering informs the CLG 1 that the CLD 2 busy and announces that one of four call processes needs to be selected as a subsequent call process, and the CLG 1 selects one call process and dials its selection number. An REG 7 receives the selection number from the CLG 1 through the LC 11 and SW 8 and sends it to the CPU 9, which performs the call process corresponding to the selection number.

Title: Optical ad converter and optical da converter
Inventor: NAKAMURA TAKASHI
IPC: G02F7/00
Filed: 1993-09-06
Abstract: PURPOSE:To provide the optical AD converter of simple constitution which can operate at an extremely high speed. CONSTITUTION:A frequency modulator 9 modulates the frequency of a local oscillator 11 with an input electric signal generated by an input electric signal source 10 and outputs a modulated wave including amplitude information on the input electric signal as frequency information. Then a spatial optical phase modulator 3 excites an ultrasonic wave in a medium having acoustooptic effect with the modulated wave. Then the medium varies in refractive index through optoelastic effect to impose phase modulation on a passing light beam. When the phase-modulated light beam is processed by Fourier transformation through an optical lens 5, the spectrum distribution of the modulated wave is generated and displacement of the light beam corresponding to the amplitude of the input electric signal is obtained. A photodiode arranged on the projection surface of the optical lens 5 receives the spectrum distribution of the modulated wave and outputs of respective elements of the photodiode array 6 are passed through a comparator 7 having a proper threshold value and are converted into a digital signal.

Filed: 1982-12-17
Abstract: PURPOSE:To increase a response detecting margin by providing a switch circuit short-circuiting an inductance circuit of a feeding circuit to detect stably a calling signal at a subscriber terminal. CONSTITUTION:At the transmission of a ringing a bell of a telephone set TEL is rung by a path of ground, ring signal source CR, resistor R1, switch S1, telephone set TEL, switch S6, switch S7, feeding resistor R3 and battery at the positive half cycle period; and a path of battery, resistor R2, switch S2, telephone set TEL, switch S1, resistor R1, ring signal source CR, and ground at the negative half cycle. The detection of response is attained by a detecting circuit TRIP. Since inductances L1, L2 of the feeding circuit are short-circuited by the switches S7, S8 during the transmission of a ringing, the adverse effect of inductance is avoided. The delay in the leading of a current waveform by the inductance L1 when the signal is changed over from the negative to the positive half cycle is prevented, allowing to prevent the reduction of detecting margin of the TRIP circuit.
