IPC: B29D28/00
Filed: 1993-09-24
Abstract: PURPOSE: To easily form ultra-microapertures by heating a film until the ultra- microaperture having a predetermined area is obtained in a state that the film is unconstrained after the ultra-microapertures are formed, in a method for forming a generally uniform pattern of ultra-microaperture in a thermoplastic film. CONSTITUTION: A thin (below about 10 mil) thermoplastic film 14 delivered from a supply roller 12 is supplied to a first nip 16 between a convey roller 18 and a nip roller 20, and conveyed to an ultrasonic vibrator 40 by an endless conveyor belt 22 made of a wire mesh screen. Then a generally uniform pattern of ultra-microapertures is formed on the film 14 by the vibrational energy (ultrasonic vibration) generated from an ultrasonic horn 50 under a condition that the liquid is sprayed from a spray nozzle 60. Then the film 14 is supplied to a high temperature air source 76 under a condition that it is unconstrained, and the film is heated to a temperature where the microapertures shrink to form ultra-microapertures having an area ranging from at least about 1 square micrometer to less than about 10 square micrometers.

Title: Method and device for automatic frequency control
Inventor: YAMASHITA HIROSHI
IPC: H03J7/02
Filed: 1990-09-29
Abstract: PURPOSE:To attain the frequency conversion with high stability even when a frequency modulation(FM) wave is used for an object wave by devising the device such that an output is obtained through frequency automatic control without use of a pilot signal when a speech signal is in existence while a voice activation function is introduced to the device. CONSTITUTION:A control section 17 controls a voltage controlled oscillator 26 so as to keep a just preceding state before no speech signal is received based on a pilot signal till the speech signal is received when the section 17 discriminates it that the speech signal is not received based on a detection signal and a count data. Thus, the pilot signal and the speech signal subject to frequency conversion and compensation at a frequency conversion section 27 are sequentially fed to a demodulator 23, in which a demodulated output S1' is obtained. That is, when the speech signal is received, no pilot signal is used to allow the compensation of frequency conversion for the speech signal.

Title: Frequency division circuit
Inventor: YAMADA HARUYASU
IPC: H03K23/00
Filed: 1985-11-19
Abstract: PURPOSE:To improve the frequency division characteristic to the limit of the device by blocking the effect of a collector-base capacitance of a transistor (TR) by means of the circuit. CONSTITUTION:A signal entering the input gate of TRs 7, 8 is read at the trailing of an input signal from a terminal 14 and an inversion signal is outputted to load resistors 12, 13. The signal is fed back to bases of TRs 20, 21 via the collector-base capacitance of the TRs 20, 21, but since the level of the base of the TRs 20, 21 is fixed by a bias voltage, the emitter level of the TRs 20, 21 is unchanged. Thus, the feedback to the base of the TRs 7, 8 being input gates is blocked thereby reducing the delay of signal.

Title: Starting of metal vapor laser equipment
Inventor: OGAWA TOMOKO
IPC: H01S3/097
Filed: 1990-09-28
Abstract: PURPOSE:To let uniformed and stabilized high density discharge and high efficiency oscillation to be carried out by heating with a specified laser gas pressure, generating metal vapor, and the once decompressing to a pressure lower than the operation pressure, and increasing up to the operation pressure, thereby oscillating. CONSTITUTION:In either an excitation system whose operation gas pressure is lower or a horizontal excitation system whose operation gas pressure is higher, heating is carried out at laser gas pressure P1 capable of preventing impurities generated in a plasma tube from being deposited to a mirror and metal vapor is generated. After the generation of the metal vapor, the laser pressure is reduced to low pressure 2, which is lower than the actual operation pressure, thereby removing the impurities in the plasma tube and embodying a uniform metal vapor distribution in the space. Then, buffer gas is charged again so as to raise the laser gas pressure up to the operation pressure. Successively, discharge is carried out between an anode 7 and a cathode 8 so as to excite laser medium and oscillate laser. This construction makes it possible to embody high density discharge and high efficiency oscillation and moreover extend service life and attain larger output results.

Title: Circuit and method provided with hot electron protection
Inventor: YOSEFIN MARK
IPC: H03K17/082
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a protective circuit for a hot electron. SOLUTION: For an I/O circuit 100, the output receives a voltage VPAD. The voltage VPAD temporarily becomes higher than a critical voltage VDSMAX> VDS1 between the drain and source of a first N-FET (110, N1) in a conductive state acting as a pull-down device. By a serially connected second N-FET (113, N3), the first N-FET is protected from degradation caused by hot electrons. A variable drain-source voltage VDS3 is added to VDS1 . A comparator 150 compares the received voltage VPAD with a supply voltage VCC and pulls the gate G of the second N-FET (N3) to VPAD or VCC. Thus, the electric conductivity of the second N-FET (N3) is changed and VPAD is distributed between VDS1 and VDS2 . It is convenient when the comparator 150 is constituted of two P- FETs (P1, P2, 160, 170).

Abstract: PROBLEM TO BE SOLVED: To provide a multi-carrier digital modulation transmitter capable of suppressing spurious radiation and improving the efficiency of a frequency band without depending on the performance of a filter and sufficiently suppressing code errors. SOLUTION: A data distribution circuit part 1, a multi-valued number control part 2 and a signal point arrangement part 3 are provided in a transmission part TI and thus, a carrier whose transmission condition is deteriorated like a band end carrier is transmitted as a signal for which a multi-valued number is lowered compared to the carrier other than a band end inside a band and is returned to original data by the signal point identification part 11, multi- valued number control part 12 and data alignment circuit part 13 of a reception part RI.
