Title: Treating method of outer semiconductor layer for rubber, plastic insulated power cable
Inventor: SATSUMOTO KOJI
IPC: H02G1/14
Filed: 1993-09-13
Abstract: PURPOSE:To allow the formation of an outer semiconductive layer treating part regardless of the skill of worker by forming a shrinkage tube layer of a 'Teflon(R)' or silicon rubber based shrinkage tube on a conductive paint applied to a cable insulator exposed by removing an outer semiconductive layer from a cable and then heating the shrinkage tube layer. CONSTITUTION:A 'Teflon(R)' or silicon rubber based shrinkage tube, which does not adhere to the surface of a cable insulator 2 even when it is thermally fused, is fitted over the part contiguous to the outer semiconductive layer 1 of the cable insulator 2 being exposed by cutting off the outer semiconductive layer 1 at the terminal part of a cable and then it is heated to form a shrinkage tube layer 4 over the insulator 2 and the part 3 applied with conductive paint. A heating pipe 5 is disposed on the outside thereof in order to heat the insulator 2 at a temperature higher than the melting point thereof thus fusing the surface thereof. Consequently, the flat inner face of the tube is shifted to the part 3 by the expanding force of the insulator 2 and the compressive pressure of the tube layer 4 resulting in the formation of a flat and voidless semiconductive layer treating part.

Title: Gas entrainment pipe
Inventor: NAKASE TAKESHI
IPC: F16L55/07
Filed: 1994-10-19
Abstract: PURPOSE: To obtain a device which has a simple structure, requires no power for operating it, works accurately and has high reliability by placing openable pipes respectively around the upper end of a gas stagnating part and in a fluid outflow pipe of the stagnating part. CONSTITUTION: A vent pipe 1 is fixedly installed in a water chamber 2 on the exit side with vent pipe fittings. As the velocity of cooling water in an outflow pipe 3 is far higher than that in the water chamber 2 when cooling water is continuously supplied into a heat exchanger, the cooling water in the vent pipe 1, whose lower end is inserted into the outflow pipe 3, flows down into the pipe 3 at a fluid velocity approximate to that in the pipe 3. Accordingly, the stagnating air in the upper part of the water chamber 2 is sucked through the pipe 1 into the pipe 3 and is ejected outside by the cooling water flowing in the pipe 3 at a high velocity.  When this action continues, the stagnating air in the water chamber 2 gradually decreases, a water level 5 rises and reaches the upper end of the pipe 1 at last and the cooling water flows into the vent pipe 1 together with the rest of air to fill the water chamber 2 with the cooling water.

Title: Clock extraction circuit

IPC: H04L7/033
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce jitters in a synchronized clock concerning a clock extracting circuit to be used for a device for demodulating a multi-phase modulated signal or an orthogonal amplitude modulated signal. SOLUTION: A clock frequency component is extracted from an input signal 1 by a digital filter 2, phase difference between that output signal and a clock 7 is detected by a phase comparator 3, an oscillator 6 is controlled by a loop filter 5 so that the phase difference can be '0', and the clock 7 synchronized with the clock frequency component contained in the input signal 1 is outputted. In this case, a selection circuit 9 switches the coefficient train of the digital filter before and after the synchronization of the clock corresponding to a signal from a synchronism decision circuit 8. Before the synchronization, the pull-in range of frequency is widened by widening the passing band of digital filter but after the synchronization, jitter in the clock is suppressed low by narrowing the passing band.

Title: Carrier system
Inventor: NAKAMURA HISATO
IPC: H01L21/677
Filed: 1987-10-07
Abstract: PURPOSE:To prevent foreign materials from sticking to a carrying load by spraying fluid to form a flow layer on the surface of a flow layer formation materials and by carrying the load upon the flow layer. CONSTITUTION:When fluid 8 is sprayed onto the surface of a flow layer formation materials 6, fluid 8 is bent along the surface of the flow layer formation materials 6 and a flow layer 9 of fluid 8 is formed thereon because of the friction with a wall surface and the inner friction through fluid 8 due to the viscosity. If a carrying load is put on the flow layer 9, the load is supported floating above the flow layer formation materials 6 through the flow layer 9, and the load is carried along the flow layer. Since the flow of fluid 8 is formed along the flow layer formation materials 6 in carrying, the load is prevented neither from being lifted to the upper surface nor from disturbing a vertical downward layer flow. Foreign materials are thus prevented from sticking to the load.

Filed: 1987-10-07
Abstract: PURPOSE:To form a multi-domain orientation thereby realize uniform display characteristics and a high contrast ratio, by using a liquid crystal composition containing a specified substance having two or more asymmetric carbon atoms in the molecular chain. CONSTITUTION:In a liquid crystal electro-optical device wherein a liquid crystal composition containing a ferromagnetic liquid crystal is put between electrodes and between a pair of parallel base plates forming an orientation section for an initial arrangement of liquid crystal material, said liquid crystal composition contains a substance of formula I, wherein R1 is a hydrocarbon group (e.g., a group of formula II) and R2 is a hydrocarbon group having two or more asymmetric carbon atoms in the molecular chain (e.g., a group of formula III). This enables the multi-domain orientation to be formed between said parallel base plates, thus, giving a uniform orientation as a whole without the occurrence of zigzagging etc., so that uniform display characteristics and a high contrast ratio can be realized. Furthermore, uniform liquid crystal drive as a whole becomes possible because of the uniformity of inversion characteristics of the multi-domains.

Title: Tachometer
Inventor: YAMAMOTO HIROYUKI
IPC: G01P3/44
Filed: 1984-11-30
Abstract: PURPOSE:To obtain a highly accurate techometer with simple construction, by detecting a strain caused in a circular magnetic strain line due to an elastic wave generated therein using a reverse magnetic strain effect. CONSTITUTION:As a driving current of a sine wave is applied to a coil 31 of an elastic wave driving section 30, a strain is caused in a magnetic strain line in the driving section 30 (point A) by a magnetic strain effect and propagates through the magnetic strain line 10 as elastic wave. Then, as the elastic wave enters a magnetic path of a detector section 50, the strain is detected as voltage signal using a reverse magnetic strain effect. So, with the rotation of a rotating shaft 40, the frequency of the signal detected with the detector section 50 comes to differ from that of the driving signal fed to the driving section 30 due to Doppler effect. The difference between the detection signal and the driving signal is proportional to the angular velocity of the rotating shaft 40. Thus, the revolutions of the rotating shaft 40 can be determined by extracting the voltage obtained by a detection coil 54 responding to this difference of the frequencies.
