Title: Automatic channel searching and selecting device
Inventor: ISHII TOMOHIDE
IPC: H04N5/44
Filed: 1981-12-28
Abstract: PURPOSE:To discontinue the channel searching in the case of a ferroelectric field and to set the prescribed value of the ferroelectric field, by discriminating a high electric field or a weak electric field in accordance with whether a band width where the AFC voltage is higher than a certain level is higher or lower than a prescribed level in case the automatic channel searching is discontinued for a signal receiver. CONSTITUTION:When a stop sensitivity changeover switch 7 is set at the B side, the AFC voltage is compared with reference voltages VL and VH through comparators 3 and 4 of a detecting circuit 2. In case a detection output of synchronizing signal exists when the AFC voltage is set between both reference voltages, a channel searching stop signal is generated from a gate 8. In this case, the channel searching is discontinued regardless of a weak electric field. When the switch 7 is set at the A side, the comparator 3 detects that the AFC voltage is higher than the voltage VH. Then a monostable multivibrator 9 is driven to deliver a pulse of a certain time width T. In case the  AFC voltage is set at a high level for a period longer than the time width T, a channel searching stop signal is delivered from the gate 8. While no stop signal is delivered in the case of a weak electric field signal to have the skipping. The limit of the discontinuation can be set freely by changing the width of the output of the vibrator 9.

Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To make synchronization complete in a short time with a simple configuration by providing a 2nd count means sending a reset signal and a serial data signal to a 1st count means respectively. SOLUTION: A program clock reference(PCR) counter 26 gives a reset signal S20 to PCR counters 31, 32 on the occurrence of a carry to reset low-order 9 bits of the count and gives a serial data signal S21 to the PCR counters 31, 32. Furthermore, the PCR counter 26 successively gives the serial data signal S21 to the PCR counters 31, 32. The serial data signal S21 sends a signal PCR-B being high-order 33 bits of the PCR in a serial signal to make them coincident with high-order 33 bits of the PCR counters 31, 32. Thus, the count of the PCR counters 31, 32 is synchronized separately with the count of the PCR counter 26 with respect to the low-order bits and the high-order bits.

Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a gas circuit breaker of small size and high reliability. SOLUTION: A moving contact of a breaking device housed in a metal tank 1 is driven with a shaft 18 which conducts linear motion. A driving shaft 5 of a driving device 3 is connected with a connecting means 22 coaxially arranged as a main shaft 9 to the main shaft 9. The rotating force of the main shaft 9 is transmitted to the shaft 18 through a lever 6 and a link 7.

Title: Deposition of thin film
Inventor: YOSHIMURA TOSHIYUKI
IPC: G03C1/74
Filed: 1993-08-30
Abstract: PURPOSE:To facilitate deposition of film on a circular substrate by providing means for rotating the liquid level and a monomolecular film and imparting centrifugal force externally to the monomolecular film for the purpose of orientation thereof on the liquid level thereby shortening the time required for deposition of film. CONSTITUTION:A rotary mechanism section 14 is driven to rotate at 1000 r.p.m. Consequently, the under layer liquid 16 and the material liquid 17 are spread on a semiconductor 11. Steady state takes place upon elapse of about 15sec. Under steady state, a monomolecular orientation film is formed on the under layer liquid 16, i.e., a hydrophilic part 18. Since abrupt increase of r.p.m. causes scattering of the under layer liquid 16 and the material liquid 17, the r.p.m. is preferably increased stepwise.

Title: Check valve
Inventor: AREKUSANDAA AIHIHORUN
IPC: B60T8/34
Filed: 1990-08-14
Abstract: PURPOSE: To restrict generation of noise, and speedily open a valve by limiting a cutout at an end section of a collar form having the cutout to receive a ball body on the side of a valve seat and enclosing the ball body roughly to a large circle. CONSTITUTION: As opening pressure is obtained in an inflow hole 3, a ball body 8 is lifted from a valve seat 4 against force of a spring 10, and pressure medium flowing into a hole 5 collides with an end section 17 of a collar form of a support member 9 to accelerate opening of a check valve 1. In this case, the ball body 8 is enclosed by the end section 17, so pressure medium is discharged from a free surface of the ball body 8. As a result, an eddy is formed on the opposite side of the ball body 8 to the valve seat 4, so the ball body 8 is not vibrated in axial or radial directions. Pressure medium flowing on the ball body 8 and the end section 17 of the support member 9 thus flows from the hole 5 into a discharge port 7 to be discharged from the discharge port 7 without generating noise at the check valve 1.

Title: Ceramic filter and its production
Inventor: SUDO HIDEKAZU
IPC: B22D43/00
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To suppress occurrence of stains at local parts of a filter and to lower the amount of B or Si being eluted into molten Al by performing cooling by natural cooling up to a specified temp. and keeping the temp. at the specified temp. for a prescribed time. SOLUTION: A ceramic filter is obtained by kneading prescribed amounts of aggregate particles and an inorganic binder raw material, forming and drying the mixture, then heating the dried formed body up to 1,150 to 1,400 deg.C to melt the inorganic binder raw material, thereafter, naturally cooling the heated material up to 870 to 750 deg.C and keeping the temp. at 870 to 750 deg.C for 3 to 9 h (annealing treatment). When the temp. at annealing treatment is higher than 870 deg.C, the corrosion resistance of the filter to molten Al is decreased and the molten Al is contaminated at the time of filtering and further the bending strength is lowered. Thereby, as the cross-sectional area of the flow passage for filtering is reduced and the permeability of Al is lowered, dispersion occurs in treatment quantity.  When the temp. at annealing treatment is lower than 750 deg.C, the annealing treatment results no effect. When the annealing time is shorter than 3 h, the effect of the annealing treatment is small and, when the annealing time is longer than 9 h, the productivity becomes low.
