Title: Centrifugal process of resin concrete pipe
Inventor: KAMIGUCHI SATOSHI
IPC: B29C70/00
Filed: 1987-08-07
Abstract: PURPOSE:To make it possible to facilitate the operation, maintenance and cleaning of mixers and feeders and realize the effective production with a centrifugal machine, by feeding a resin concrete mixed and kneaded with a thermoset agent for the main body of a pipe and feeding a resin to which a cold curing agent is added or a resin mortar for the innermost layer of the pipe. CONSTITUTION:A mold is rotated on a centrifugal machine, a resin concrete to which a thermoset agent for medium- and high-temperature curing is added is fed from the openings of the ends a bit less than the required wall thickness of a pipe, and then a required quantity of glass fiber is fed. After that, a resin mortar to which a curing agent is fed and the innermost layer of the pipe is molded. The curing of resin concrete takes place hardly at the ambient temperature and the removal work is very easy even in summer. Because the resin or resin mortar for the innermost layer is sufficiently fluid, the addition of the cold curing agent near the top of the pipe reduces the cleaning work remarkably and the curing time can be controlled according to the amount of curing agent added. The resin concrete of the main body of pipe is cured separately in a proper heating chamber.

Abstract: PURPOSE:To make it possible to operate a power source voltage detection circuit without increasing a manufacture process by laying out only one party of a first conductor type transistor which is differentially paired with a differential circuit to the end of a well region. CONSTITUTION:An N channel transistors (Nch-Tr) 108 and 109 are differentially paired with each other, Tr 108 on one side is laid out to the end of a P type well region (P-WEL). When Tr is laid out to the end of the P-WEL, the threshold voltage (Vth) of the Tr is subjected to change. As it approaches, the concentration of the P-WEL will become thinner, which lowers the Vth of the Nch-Tr on the thinner P-WEL. Therefore, the Vth of the Nch-Tr turned to a standard Vth of the Nch-Tr by laying out one party of Nch-Tr, which is differentially paired, to the end of the P-WEL, thereby operating a power source voltage detection circuit, using the differential Vth.

Filed: 1985-09-09
Abstract: PURPOSE:To quicken the locking speed of a control loop by providing a median filter so as to prevent error information due to impulse noise from being fed to an integrator. CONSTITUTION:A comparator 34 compares a clamp reference value and an output from the median filter 40 during the clamp level period and its error information is fed to a loop filter 36 via a gain device 35. The filter 36 has an integrator 41 to eliminate the noise component and gives it to an adder 32 via a D/A converter 37. Thus, when a clamp level signal in an input signal is converted into a digital value in the loop, the adder 32 applies DC component restoration to make the value equal to the reference value. The restoration output is sent after A/D conversion 33 and led to the median filter 40, from which 2N+1 (odd number) of samples are extracted and the median of each sample is given to the comparator 34.

Filed: 1989-08-02
Abstract: PURPOSE:To reduce heat generation of a transformer and a ballast impedance element by controlling the ratio of coil wires of the transformer by a timer circuit operated on the basis of a lighting command signal. CONSTITUTION:Since a transformation ratio control circuit 9 is connected to a transformer 5' on the side where a ratio of coil wires is increased, an output voltage of the transformer 5', on the secondary side becomes high so that a discharge tube 6 starts lighting with the application of a voltage higher than a lighting start voltage. Upon turning-on of a lighting command signal CNT, a timer circuit 8 is operated to output a signal into the transformation ratio control circuit 9 after a predetermined elapse, thereby switching the transformer 5' in such a manner as to make the transformation coil wires small. When the ratio of coil wires of the transformer 5' becomes small, the output voltage of the transformer 5' is decreased. Therefore, the output voltage of the transformer 5' is small when the discharge tube 6 is lit so that the impedance of a ballast impedance element 7 can be decreased and an electric power to be consumed by the transformer 5' can be reduced.
