Title: Groove cover support frame structure for circular channel
Inventor: NISHIWAKI TATSUO
IPC: E03F5/04
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To ensure an effective opening size by a method wherein two L-type steel plates are welded together through a coupling plate so that the rise surfaces of the L-type steel plates are arranged longitudinally in parallel facing each other at the upper part of the opening part of a circular channel, and a square bar steels to support the groove cover are formed in parallel to the coupling part between the coupling plate and the L-type steel plate. SOLUTION: L-type steel plates 3 are arranged at the upper part of the opening of a circular channel 1 made of precast concrete such that rise surfaces are positioned facing each other in parallel in a longitudinal direction. A plurality of coupling plates 5 made of a steel plate formed such that the two L-type steel plates 3 are welded with a distance therebetween are arranged at equal interval. A square bar steel 6 to support a groove cover 7 is formed in parallel to the upper edge of a coupling part of a coupling part between the coupling plate 5 and the Ltype steel plate 3. Further, a hole 4 for securely mounting is formed in the lower horizontal plane of the L-type steel plate 3. This constitution ensures the wide effective size of an opening since the structure of a holding part for the groove cover 7 to be placed thereon is formed by a comparatively finer square bar steel 6.  Thus, the effective opening size is increased to a value higher than a narrow opening size.

Abstract: PURPOSE: To provide a frequency tracking device for burst communication equipment in which a frequency and a phase of a carrier are stable even in the case of burst transmission. CONSTITUTION: A difference signal passing hold circuit 14 is provided between a frequency comparator circuit 2 and a carrier generating circuit 3.

Title: Flip-flop circuit
Inventor: MAENO HIDESHI
IPC: G11C19/00
Filed: 1989-12-08
Abstract: PURPOSE:To execute a normal shift operation even when there is skew in a clock signal by inputting the first clock signal to the enable terminal of a first latch circuit while inverting the clock signal or not inverting it. CONSTITUTION:For a second latch circuit 1b, a data input terminal D2 is connected to an output terminal Q1 of a first latch circuit 1a. The output terminal of a control gate 8 is connected to an enable terminal EN of the second latch circuit 1b and first and second clock signals CK and SCK are inputted to two input terminals. The first clock signal CK is inputted to the enable terminal EN of the first latch circuit 1a while being inverted or not being inverted. In such a way, since the both latch circuits 1a and 1b are controlled by the first and second clock signals CK and SCK, the both latch circuits 1a and 1b can be simultaneously set in a holding state. Thus, even when there is slight skew in the clock signal, the normal shift operation can be executed.

Title: Sealed type compressor
Inventor: SANUKI MASAMI
IPC: F04C29/02
Filed: 1993-12-20
Abstract: PURPOSE:To allow the oil separated from the compressed fluid to recirculate to a pump part in a stable manner, without using the means such as an oil supply pump. CONSTITUTION:The fluid such as coolant which is compressed by a pump part 5 driven by a motor part 4 passes through a gas passage 10 on the periphery of the motor part 4, and flows into an oil reservoir chamber 7 on the opposite side to the pump part 5. During this time, the motor part 4 is cooled by the fluid. In the oil reservoir chamber 7 which possesses the gas/liquid separating function, the oil (lubricating oil in the pump part 5) is separated and stored from the inflow fluid. Since the pressure in the oil reservoir chamber 7 becomes lower than the pressure in the vicinity of the discharge port of the pump part by the pressure loss of the gas passage 10, the level of the stored oil is increased by that portion. The oil is recirculated to a low pressure part at the center of the pump part 5, passing through the oil passages 2b, 2c, 2d, etc. which are formed inside the wall itself of a housing, by only the pressure difference without using the oil pump.

IPC: G06F11/28
Filed: 1988-12-19
Abstract: PURPOSE:To check a program generation error efficiently by generating data where coupling tables outputted by procedures of a processing program are accumulated and checking the states of resources corresponding to procedures to be coupled. CONSTITUTION:The output resource cumulative data 6 is generated by accumulating successively the coupling tables outputted by procedures before the procedures are coupled. Then continuous tables 5 and 6 as input resources of a procedure 5 to be checked are taken out to know that a procedure before the procedure 5 is a procedure 4, and the cumulative data 6 of the procedure 4 is taken out. Then it is checked whether or not the resources corresponding to the coupling tables 5 and 6 are in precedent cumulative data and when the data is already outputted, it is judged that the program is normal. Consequently, when the processing program is generated, an error is checked efficiently by the simple processing.
