Abstract: PURPOSE:To prevent electrostatic troubles between a human body and any object to be discharged and also in a charged object itself by forming an electrostatic charge eliminating means from a discharging means to eliminate electrostatic charges using a discharging effect and a heating means to eliminate electrostatic charges using a heat emitting effect. CONSTITUTION:Between a power line 15 and an earth line 16 an electrostatic charge eliminating device 20 is installed, in which a heater 23 is installed consisting of a core 23a of acrylic resin provided in a nonconductive case 21 and a nickel-chromium wire coil 23b wound on the core 23a. A discharge electrode 26 is formed from an iron ball 26a as a counter-electrode and a metal sleeve 26b as a counter-electrode, which is fitted on the iron ball 26a through spcers 27, 27a, and arranged in such a way that the ball 26a touches the coil 23b.

Title: Laying of vacuum sewerage
Inventor: YAMANAKA JUNICHI
IPC: E03F5/22
Filed: 1991-12-11
Abstract: PURPOSE:To efficiently prevent accumulation of foreign matters at the laying of vacuum sewerage in which lowering of the degree of vacuum due to a lift when the sewerage passes under an obstacle such as a river is prevented. CONSTITUTION:An upstream side vacuum sewer pipe 2 provided on one side of a river 1 and a downstream side vacuum sewer pipe 3 provided on the other side are connected to each other by a water pipe 14 passing under the river 1 and by an air pipe 5 passing over the river 1. The diameter (d) of the water pipe 14 is smaller than the diameter D of the upstream side vacuum sewer pipe 2. Therefore, sewage in the upstream side vacuum sewer pipe 2 is allowed to flow into the downstream side vacuum sewer pipe 3 because of the principle of a siphon and the degree of vacuum transferred from a vacuum station to the downstream side vacuum sewer pipe 3 is seldom lowered and is then transferred to the upstream side vacuum sewer pipe 2. Because the diameter of the water pipe 14 is small, a large flow velocity can be obtained and solid matters inside the water pipe 14 are efficiently discharged toward the downstream side vacuum sewer pipe 3. The area for collecting sewage using a vacuum sewage collecting system can be enlarged.

Title: Phase detection circuit
Inventor: ABE KENJI
IPC: H04L27/233
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce the size of the phase detection circuit by converting a phase modulated signal into a rectangular signal by shaping its waveform and holding a signal corresponding to the logical value of the rectangular signal by a capture signal having a reference phase for a carrier signal as a demodulated data signal. SOLUTION: A receiving circuit 1 receives a signal transmitted from a card of an electronic money system and sends a BPSK modulation signal obtained by advancing or delaying the phase of the received signal by 180 deg. to a waveform shaping circuit 2. The circuit 2 shapes the waveform of the received signal as a binary rectangular signal by level discrimination and sends the waveform shaped signal to the data terminal D of a D flip flop(DFF) circuit 3. A capture signal generation circuit 4 sends a capture signal generated from the carrier signal to the clock terminal of the DFF circuit 3. The DFF circuit 3 stores the logical value of the rectangular signal on the data terminal D in each reception of the capture signal and outputs the stored value to an output terminal Q as demodulated data. Thus a modulated signal can be demodulated only by the digital processing circuit.

Abstract: PURPOSE:To improve the breakdown strength of punch-through between field inverting voltage and elements without lowering junction breakdown strength by leaving a polysilicon film which is deposited at sidewall parts of a film which is able to withstand oxidation and is treated with patterning. CONSTITUTION:An oxide film 2 is formed on a silicon substrate 1 and polysilicon film 3 is formed. Then, for example, a film 4 consisting of Si3N4 and having a resistance to oxidation is laminated. Further, the film 4 consisting of Si3N4 and having the resistance of oxidation is left to a place in which an element region is formed by performing patterning. The film 5 consisting of SiO2 is formed to protect the film 4 having the resistance to oxidation and a polysilicon film 6a is formed on the film 5. Subsequently, the polysilicon film 6a located at places other than neighborhood of sidewall parts of the film 4 is removed selectively with a RIE process. This approach keeps the element region and an ion injection region 7 of a field apart in comparison with the cases where devices are manufactured by using conventional processes and then improves junction breakdown strength.
