Title: Filter
Inventor: IGA HIROSHI
IPC: B01D37/04
Filed: 1982-03-19
Abstract: PURPOSE:To perform properly an operation control such as an exchanging of filter medium, by detecting the reduction of filtration time at one cycle, in a filter where filtration and regeneration are repeated. CONSTITUTION:A filtration is started by the time-up of a filtration timer which is turned on by a filtration starting signal of a limit switch LS1. On the other hand, a regeneration is started by a turn-on signal, obtained by earlier one of either the time-out of a timer or the time ''on'' of a detector 20 used for detecting the inner pressure of a filtering chamber. When the LS1 is turned on after the completion of regeneration, the filtration is performed again and is repeated thereafter. An alarm is announced when the PS 20 is turned on while the timing of detecting timer, which sets the time of each cycle from the start of filtration to the time that the detector (PS) is turned on, and the exchanging of a filter medium or its preparation is performed. After the time out of the detecting timer, the alarm is not announced even when the PS 20 is turned on.

Title: Production of semiconductor device
Inventor: KAWAKITA KENJI
IPC: H01L21/76
Filed: 1984-03-08
Abstract: PURPOSE:To form an active region whose bottom face and side faces are surrounded by oxide films, by selectively forming a non-oxidizable film in apertures of a semiconductor substrate having the face orientation of 100, etching the substrate anisotropically in face orientation with the use of the film as a mask, and oxidizing it selectively. CONSTITUTION:A silicon substrate 31 having a crystal face orientation of 100 is provided with apertures 32. A thermal oxidization film 33 is formed on the whole surface of the substrate and a silicon nitride film 34 is adhered thereto. The oxide film 33 is etched with the use of the silicon nitride film 34 as a mask to expose the substrate, which is etched by KOH. Since the 100 face of the substrate is etched about 100 times faster than the 111 face, the substrate represents an etching shape which is anisotropic in face orientation, and apertures 35 are formed. The substrate is then oxidized to form an oxide film connected under an active region 37. A polycrystalline silicon film 38 is buried in each of the apertures 32 and an oxide film 39 is formed. In such a manner, oxidization in the transverse direction can be reduced, and the strain due to expansion in the oxidized portions can be reduced while the reduction in volume of the active region can be minimized.

Title: Ultrasonic measuring method and equipment
Inventor: KOIDE MAKOTO
IPC: G01N29/07
Filed: 1993-02-10
Abstract: PURPOSE:To make possible highly accurate automatic measurement of the propagation time of ultrasonic wave by controlling the time interval between adjacent received waves to Ice equal to the period of a continuous oscillation wave and then measuring the period of the continuous oscillation wave. CONSTITUTION:An ultrasonic receiver 100 receives a multiple reflection signal which repeats reflection between an oscillation plate 3 and a reflector 4. The signal thus received is then amplified 6 and AGC amplifying sections 7, 8 amplify only the first and second received waves among multiple waves being received for each transmitting wave. The amplified signal is converted 9, 10 into a single pulse digital signal which is received by a continuous oscillation control circuit 27. The circuit 27 delivers a continuous oscillation signal having frequency fOUT and period t3 equal to an ultrasonic wave propagation time tl to a time measuring circuit 24. The circuit 24 measures the multiperiod component of the continuous oscillation wave by means of a counter having open reference clock and determines a single period time t3 based on the average value thereof. This constitution allows more accurate measurement than the frequency of reference clock. The measurement is employed as the propagation time tl for determining an absolute sound velocity.

IPC: B23Q1/40
Filed: 1985-03-08
Abstract: PURPOSE:To fix a table body with good response merely by controlling electrically by installing an elastic body between a linear bearing and either of a base or said table body. CONSTITUTION:When a pulse is inputted in the movable member 19 of a linear motor 17, the movable member 19 is fed in the longitudinal direction of a base 1 at every 1/4 pitches with respect to the fixed member 18 of a table body 3 while maintaining a gap (g) which is determined by load, suction force between the movable body 19 and the fixed member 18, and an elastic modulus of a conical spring 8 between each linear bearing 2 and the base 1. When the table body 3 is to be fixed, a current for the movable member 19 is increased to increase the suction force toward the fixed member 18, while the conical springs 8 are deflected to reduce the gap (g), which rapidly increases the suction force to firmly hold the table body 3. When the gap l between the bearing 2 and the base 1 becomes zero, the fixed member 18 is brought into close contact with the movable member 29, stably holding the table 3.

Title: Voltage controlled oscillator
Inventor: YOSHIMURA TSUTOMU
IPC: H03K3/354
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a voltage controlled oscillator which can easily generate the oscillations by using a ring oscillator, a 1st bias circuit including a replica circuit and a differential gain increase circuit which increases the differential gain of a differential amplifier. SOLUTION: The external control voltage VC is given to a ring oscillator 1 and a bias circuit 2, and the reference voltage VR is given to the circuit 2. The clock signal produced by the oscillator 1 has a cycle double as much as the sum of delay time of a differential buffer, and the delay time of the differential buffer varies according to the voltage VC. Thereby the frequency of the clock signal varies according to the voltage VC. At the same time, a minute potential difference is caused between an output node Nnc and an inverted output node Nnd of the differential buffer. Then a differential gain increase circuit 3 supplies a current in the direction where the potential difference is increased. As a result, the differential gain of the differential buffer of the final stage is increased and the oscillator 1 can easily generate the oscillations.

Abstract: PURPOSE: To simply separate water and cement by a method wherein water contg. cement is flowed onto a mesh belt above a vacuum tank and cement is settled, on which cement-containing water is flowed while the vacuum tank is vacuumed.  
     CONSTITUTION: Cement-containing water such as mixer-cleaned water is freed from gravels and sand, the remaining cement-containing turbid water is flowed from pipe 7 at a given rate on a mesh belt 1 contacting the upper surface of a vacuum tank 2, so that contained cement is settled on the belt 1. While the vacuum tank 2 is vacuumed with a vacuum pump 6, turbid water is newly flowed. At this time, the settled cement acts as a filter and filters out contained cement, so that cleaned water is obtained in the vacuum tank 2. Then, vacuum operation is stopped, roller 4 is driven to cause the mesh belt 1 to be lifted from the surface of the vacuum tank, and rollers 3W5 are driven to circulate the mesh belt 1. Cement settled on the belt is separated and removed from the belt by discharge chute 9. Thereafter, the belt is cleaned with water jetted from nozzle 10 and is reused.
