Title: Continuous casting/rolling method
Inventor: KUDO HIDEAKI
IPC: B21B45/00
Filed: 1990-11-19
Abstract: PURPOSE:To obtain a high-quality roughly drawn wire without reforming an oxidized film by covering with non-oxidizing atmosphere while an ingot is reached to a continuous rolling mill after the oxidized film is removed by injecting high-pressure water to the ingot which is produced with a continuous casting machine. CONSTITUTION:After the oxidized film is removed by injecting high-pressure water to the ingot which is produced with the continuous casting machine, this ingot is covered with non-oxidizing atmosphere while it reaches the continuous rolling mill. So, the oxidized film on the surface isn't formed by re-oxidizing the ingot. Therefore, the roughly drawn wire which is obtained by rolling the ingot continuously is excellent in the quality of surface without penetrating the piece of oxidized film.

Title: Programmable read-only memory device
Inventor: TAKIGAWA ISAO
IPC: G11C16/06
Filed: 1988-12-12
Abstract: PURPOSE:To shorten the check read time by setting all output signals of address decoders in a circuit to the selected state at the time of operation of a read circuit. CONSTITUTION:When contents of all memory transistors MTs will be read out, a signal AVER, outputs of two-input OR circuits 13 to 20, and word lines A to D are set to the high level. N-channel transistors TRs 21 to 24 are turned on and digit lines E to H are made conductive. Since threshold levels of all MTs are higher than potentials of word lines at this time, the output of a sense amplifier 25 goes to the high level and an output OUT of an inverter circuit 26 goes to the low level, and it is judged that all MTs are in the write state. If there is the MT where any bit in all of the memory is in the erase state, the potential of the word line is applied to the gate and the MT is turned on, and a current flows to a digit line, and the output of the amplifier 25 is goes to the low level and the output OUT of the circuit 26 goes to the high level, and the existence of the MT in the erase state is confirmed.

Title: Heat treatment method and device for semiconductor wafer
Inventor: TANAKA TOMIO
IPC: H01L21/324
Filed: 1991-11-28
Abstract: PURPOSE:To make uniform the sheet resistance of a wafer by a method wherein, when a semiconductor wafer is heat-treated by introducing reaction gas into a heating container, a pressure in the heating container is adjusted within the range between -15mm H2O and 10mm H2O. CONSTITUTION:A furnace pressure detecting tip 21, which is mounted on the side wall of a heating container 1, detects an inside pressure of the heating container 1. The furnace pressure detected by the furnace pressure detecting tip 21 is converted into an electric signal by a furnace pressure transmitter 22. A furnace pressure adjuster 23 compares the furnace pressure signal, sent from the furnace pressure transmitter 22, and the preset value, and outputs a furnace pressure control signal. When the furnace pressure is adjusted to the range of -15mm H2O to 10mm H2O, the sheet resistance of wafer can be adjusted to almost a fixed range. As a result, the sheet resistance of the wafer can be controlled in the range of prescribed value.

Title: Pulse modulating microwave generating circuit
Inventor: KISANUKI IKURO
IPC: H01J23/40
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To eliminate jitter phenomenon and to provide a sharp and short pulse by providing a PIN diode on a microwave output circuit from a short- circuit face to an inverse sink phase position and by alternately forward/reverse- biasing thereon. SOLUTION: A PIN diode 9 is alternately biased so that it is forward-biased before an application voltage to the input terminal 2 of a magnetron 1 of a B part is raised and reverse-biased after the magnetron 1 is sufficiently raised. As a result, the microwave output of the C part which is pulse-modulated is prevented from causing rising delay. Therefore, even if the rising delay of the magnetron 1 and the jitter phenomenon are observed, the pulse width of the microwave output can be controlled by the bias timing of the PIN diode 9. The minimum pulse width of the microwave output depends on the drive capacity of the PIN diode 9 so as to provide a sharp and short pulse without any jitter phenomenon.

Title: Rotary device
Inventor: NISHIGUCHI MASAZUMI
IPC: G01D5/245
Filed: 1994-12-19
Abstract: PURPOSE: To improve the S/N ratio of a phase detection signal without using a cancellation coil by setting the opening angle of a phase detection coil to the same angle as that of one counter electrode. CONSTITUTION: The opening angle of a phase detection coil 20, namely the opening angle of a pair of coil patterns 20a and 20b, is set to 60 degrees equally to one counter electrode of a rotor magnet 6. Then, a voltage induced in the coil 20 due to the rotation of the magnet 6 generates four peaks (negative, positive, positive, and negative peaks) while a magnet 6a for detecting phase opposes the coil 20. Then, when the magnet 6a stops opposing the coil 20, current generated at a leakage magnetic field is canceled each other and the total current reaches zero since the patterns 20a and 20b are located at the magnet 6 with the same pole. Therefore, the current waveforms of the terminals 21a and 21b generate each two rising and falling pulses in one revolution. By waveform shaping according to a threshold level, the shaped phase detection signal can be obtained.
