Title: Cleaning member and cleaning method
Inventor: TAKANO MINORU
IPC: H01L21/304
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To realize easy cleaning by forming an adhesive film having specific viscosity on a semiconductor a semiconductor wafer thereby removing dust efficiently without causing any damage at the forward end part of a probe pin at all. SOLUTION: The cleaning member has such surface shape as touching the line or surface defined by the forward end part of a semiconductor measuring probe simultaneously and generally has a planar shape. An adhesive of various forms is employed as an adhesive substance and an acryl based adhesive is preferably employed in order to avoid so-called residual paste. Dust is left easily when the viscosity (JISZ0237) of an adhesive substance is lower than 100g/25mm, and a paste is left easily on the surface of the semiconductor measuring probe when it exceeds 250g/25mm and thereby the viscosity is preferably set in the range 120g/25mm-200g/25mm. Thickness of the adhesive substance is preferably set in such range as the forward part of a pin is inserted sufficiently without leaving any paste and it is generally set in the range of 10-50μm.

Title: Vane wheel of centrifugal blower
Inventor: KUMA TOSHIMI
IPC: F04D29/28
Filed: 1979-12-26
Abstract: PURPOSE: To minimize an inflow resistance through parallel arrangement of a flow direction with a small through hole in a large flow volume area and make velocity distribution uniform in a small flow volume area to prevent deterioration of a characteristic by providing a vane wheel with multiple small thrugh holes on the external side and a vane wheel with a limited number of vanes on the internal side.  
     CONSTITUTION: A vane wheel 10 with multiple small through holes 3 is formed on the external side and a vane wheel 11 with a limited number of vanes on the internal side. In this case, an inlet velocity (v) is high in a large flow volume area and a fluid flows obliquely in against a vane wheel, but the direction of a flow is parallel with a small through hole 3 when a fluid reaches the area of the small through hole 3, reducing an inflow resistance. As a result, a decrease in the discharge pressure, i.e. a loss of the said pressure is reduced. Next, an uneven velocity distribution is generated in the region of a limited number of vanes 11 over a small flow volume stretch as indicated by a group of arrow marks 23. However, the velocity distribution is rendered uniform by flowing into the area 10 of the small through hole 3 as shown by an arrow mark 29. Consequently, the deterioration of a characteristic is insignificant in the small flow volume area on account of a mixture loss of a discharge flow. Thus it is possible for a vane wheel to maintain a high efficienty over an extensive range.

Title: Production of rapidly cooled thin strip
Inventor: MIYAKE KANE
IPC: B22D11/06
Filed: 1988-07-14
Abstract: PURPOSE:To make mass production of thin strips having good edge shapes by ejecting an inert gas from the gate plates provided with a specified spacing onto the rotating plane at both ends of a pair of cooling rolls to said spacing and applying oscillation to said gate plates. CONSTITUTION:After a molten metal 7 supplied from a nozzle 6 is temporarily held between twin rolls 8, 8 and the gate plates 1, 1, the molten metal is fed downward as a thin strip 9. The gate plates 1, 1 are fixed to have some spacing from the rolls 8, 8 and the inert gas is injected 3' from the gate plates 1, 1 toward the roll 8, 8 surfaces. The penetration of the molten steel 7 to the spacing between the rolls 8, 8 and the gate plates 1, 1 is, therefore, prevented by this gas injection. The gate plates 1, 1 are slightly moved forward and backward in a horizontal direction by the operation of an exciter 5. The solidified shell developing on the inner side of the gate plates 1, 1 is, therefore, shaken off toward the kiss part when the shell grows to some size.

Title: Automatic frequency control circuit
Inventor: UETAKE TATSUYA
IPC: H04N5/50
Filed: 1988-07-13
Abstract: PURPOSE:To considerably shorten a transition period when a frequency is unstable by continuously and automatically controlling the frequency until a prescribed period lapses from when a detection signal is outputted. CONSTITUTION:When power is supplied, a detection circuit 6 detects power supply and the detection signal (f) is supplied to a timing signal processing circuit 8, whereby a high level signal is transmitted to a sample-hold circuit 5 as a period timing signal (g) which has previously been set. Consequently, the circuit operates as mean value type AFC for a rise period, and the output frequency of a frequency converter 2 is controlled to a prescribed value in a short time. When an output voltage V is raised to a prescribed voltage value where IF becomes specific, a pulse signal (p) from a timing generation circuit 7 is supplied to the circuit 5. Consequently, the circuit 5 executes a keyed AFC action in which a system becomes to a sample state and the frequency is controlled only when the signal (g) is in a high level.

Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To hold output per wave of a light signal constant and to transmit it to a linear repeater or a reproduction repeater on a down stream by detecting the number of the light signals which are transmitted at present and controlling the optical amplifier in accordance with the detected number of the signals. SOLUTION: An optical transmission terminal is constituted of optical transmission disks 1 and 2 different in wavelengths. The light signals are branched by photocouplers 3 and 4 and they are divided into the main optical signal and a control signal. The control signal is optically/electrically converted in the photodiodes 6 and 7 of a light signal number detection circuit 5 and it is inputted to the reference voltage of the negative feedback circuit 9 of an optical booster amplifier 8 and DC current is driven so that the output becomes an optimum value in accordance with the number of the light signals. The sine wave generation circuit 10 of the optical booster amplifier 8 is driven by the different frequencies in accordance with the number of the light signals and current is overlapped with the driving current of exciting LD 11.  Thus, an auxiliary signal is overlapped with the envelope of the main signal such as the light signal 12, and information on the number of the light signals is transmitted with the main signal.

Filed: 1983-09-21
Abstract: PURPOSE:To obtain an operation always stable by allowing the circuit to be reset when a power supply voltage of a system has increased to an optional prescribed value so as to avoid the use without notifying malfunction. CONSTITUTION:A booster circuit 1 boosts a device power supply V and a constant voltage generating circuit 2 generates a constant voltage B higher than the device power supply voltage V from the boosted voltage A. The constant voltage B is compared with the device power supply voltage V by a comparator 3, and when the device power supply voltage V is increased more than the constant voltage B, an output of the comparator 3 is inverted so as to apply reset to a main section 4 of the integrated circuit device. The use of this device makes it possible to know the possibility of malfunction due to the increase of the device power supply voltage V in advance and the possibility of the use of erroneous result without notice is precluded in this way. The power supply voltage V generating the said reset signal is set to an optional prescribed value from the correlation with the constant voltage B, and the operation stable at all times is obtained.
