Title: Method for polishing semiconductor wafer
Inventor: KASHIMA YOSHIYASU
IPC: B24B37/00
Filed: 1994-02-04
Abstract: PURPOSE:To quickly polish a semiconductor wafer accurately so that the semiconductor wafer exposes a mirror surface by performing polishing using colloidal silica in a specific range of length and in a specific range of width/length ratio. CONSTITUTION:A colloidal silica in a distorted shape with a long diameter of 7-1000nm and a width/length ratio of 0.3-0.8 is used as an abrasive to precisely polish the semiconductor wafer so that it exposes a mirror surface. Then, when a polishing cloth and the semiconductor wafer moves relatively under pressure, colloidal silica particle included between the cloth material surface and the wafer surface rotates but the colloidal silica particle in distorted shape cannot rotate easily as compared with the spherical colloidal silica particle, thus extremely increasing the friction force between the cloth material surface and the wafer surface. However, since the relative motion speed between the polishing cloth and the semiconductor wafer is maintained to be constant under pressure, the amount of polishing per unit area of the wafer surface can be extremely increased due to the increased friction force.

IPC: G05B9/02
Filed: 1984-01-26
Abstract: PURPOSE:To put an automatic machine in unmanned operation by generating a stop signal in response to abnormality occurrence and operation completion, storing and displaying the stop signal, and turning off a power source and powering on necessary parts by a battery. CONSTITUTION:If a shortage of material, overheating of the machine, or fire, etc., is detected, a switch 10 is closed to generate the stop signal by a stop signal generating means 1, and the signal is stored in a storage circuit 2. The stop signal generating means 4 detects repetitive operation to operate the switch 10, and the frequency of switching is counted by a counter 19; when the counted value attains to a specific value or if abnormality occurs, the stop signal is generated even before the completion of the counting operation and this signal is stored in a storage means 2'. Storage means 2 and 2' turn on LEDs 15 of display circuits 3 and 3 with the stored stop signal and also send the stop signal to an original power source turning-off means 7 to turn off the original power source of the automatic machine. In this case, storage FFs 12 of the means 12 and 12' are powered on by a backup power source Vm.

Title: Rf amplifier for tuner
Inventor: YAGUCHI SADAO
IPC: H03J3/18
Filed: 1980-02-06
Abstract: PURPOSE:To ensure a common use of the amplifier element of both the VHF and UHF bands with one unit, by supplying the output of a VHF and UHF antenna tuning circuit to the input of an RF amplifier element via an element having an impedance that is small or large for the VHF band signal. CONSTITUTION:The VHF band signal is applied to the FET1 via the coupling capacitor C1 as well as the inductor L1 having an impedance that is small enough to the VHF band signal. At the same time, the UHF band signal is applied to the  FET1 via the capacitor C3 having an impedance large enough to the VHF band  signal. Thus the capacitor C3 has a large impedance when the VHF band signal is  amplified, preventing the loss caused by the capacitor C3. On the other hand, the  impedance of the coil L1 and the capacitor C1 respectively increases when the UHF  band signal is amplified. The UHF band signal is applied to the FET1 with no loss.

At the same time, a connection is given between the collectors and bases of transistors Q1 and Q2 plus Q3 each, and the base of Q1 is connected to the base of Q3. Furthermore the constant current IO is supplied to the transistor Q4 to perform a control. Then the electric charge is charged to the capacity C with the current flowing to Q3, and at the same time the interterminal voltage of the capacity C is applied to a comparator to be compared with the reference voltage. Thus the action of shutter is controlled by the output of comparison.
