Title: Surge sensor device for centrifugal compressor
Inventor: EJIRI EIJI
IPC: F04D27/02
Filed: 1982-10-26
Abstract: PURPOSE:To make positive sensing of generation of a surge by a method wherein each of thermocouples is arranged at a position on a wall surface just before the inducer part in an impellor feeding duct and a position on a wall surface upstream spaced apart by a proper distance from the former position. CONSTITUTION:A thermocouple 10A is located at a position on the wall of a duct 8 where a back-flow area is generated and a thermocouple 10B is located at a position upstream from the former position where a back-flow area caused by a surge is not generated. Under a condition where no surge is produced, no difference in outputs is found between the thermocouple 10A and the thermocouple 10B. When the surge is produced, the output from the thermocouple 10A becomes higher than the output from the thermocouple 10B, resulting in making a difference in output.

Title: Attachable and detachable trencher device for hydraulic shovel
Inventor: SHINKAI KIYOSHI
IPC: E02F5/06
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To excavate a gutter in a position distant from a machine by integrating a cutter chain having a rotary cutter mounted thereon to a trencher. SOLUTION: A rotary cutter chain 9 is formed of a roller chain or caterpillar link chain. A cutter 10 for cutting earth and sand or rock is mounted on the cutter chain, an idler 11 is mounted on one end of a trencher 3, and a driving sprocket 12 is mounted on the other end thereof. The cutter chain 9 is slid and rotated around the idler 11, the sprocket 12 and a guide plate 13. A driving hydraulic motor 16 is integrated into the sprocket 12, and rotated by the oil pressure supplied from the oil pressure source of the hydraulic shovel to transfer the rotating force to the cutter chain 9. A rotating auger 4 is integrated to the ground surface part of the trencher 3 to gather the excavated earth and sand sideward.  Thus, a linear gutter with a precise section, which is parallel to the advancing direction of the machine and free from excessive excavation, can be excavated in a position distant from the machine.

Abstract: PURPOSE:To prevent formation of parasitic MOSFET by preventing a conductor having potential variation from existing on a high-resistance semiconductor layer between the same conductivity type regions of a switching element and a Zener diode. CONSTITUTION:A drain electrode 92 of power MOSFET 11 is in contact with a cathode region 2 of a Zener diode, an electrode 10 is in contact with an anode region 52, and a contact of the Zener diode 16 between a drain and a gate is made by being in contact with a gate electrode 7 of the MOSFET 11.

Abstract: PROBLEM TO BE SOLVED: To obtain a separating device capable of complying with a variety of packet systems of diverse digital broadcasting by constituting a filtering condition table to be used in the case of filtering of section data as a register to be changed by a software processing. SOLUTION: The filtering condition table 2 to be used in the case of the filtering of the section data is constituted as the register to be changed by the software processing. Values by every entry of in the filtering condition table 2 are compared by using an inputted section header by a comparator 3 and coincidence/noncoincidence of the filtering is judged. This judgement result is held in a result holding part 4 and when the result reaches the length of the section header, coincidence/noncoincidence of the filtering is judged. When filtering results are judged to coincide, a signal that passing of the section data is allowed is transmitted to a buffer 5 and the section data is outputted.

Inventor: AOYAMA TATSUHITO
IPC: B60R22/12
Filed: 1984-09-06
Abstract: PURPOSE:To ease coupling and uncoupling of a safety belt, by using a bilateral element of a form-memory alloy and a bias spring, which is used for rolling in and releasing a safety belt by heating and cooling. CONSTITUTION:In this rolling-in belt, a form-memory alloy 13 is incorporated, one end of which is connected to a coating wire 15.

Filed: 1994-07-18
Abstract: PURPOSE:To switch the rotational frequency of a color separation filter by stopping the write or image pickup information to a picture memory to freeze the stored information in the memory during the switching control of the rotational frequency of the color separation filter. CONSTITUTION:When a command to switch the rotation speed is inputted by a setting switch 11 at the time of image pickup operation, a CPU 13 inputs a freeze instruction signal to a picture memory 16 and stops the write of new picture information to the picture memory 16 to freeze the stored information in the picture memory 16.

A phase detection signal corresponding to the phase difference between the inputted synchronizing signal and a signal inputted through a waveform shaping device 12 is generated from the phase comparator 10 and is supplied to a servo circuit 9. This circuit 9 controls the generator 7 in accordance with this phase detection signal.

Abstract: PURPOSE:To execute the file retrieval at a high speed and to satisfactorily hold the compression efficiency by providing a block constituting means having a function for bringing low frequency side component data in frequency component data to reverse orthogonal transformation and constituting an image of every block, in the case a retrieval instruction is received. CONSTITUTION:When an image retrieval instruction is outputted from a controller 1 which receives a retrieval instruction from an operator part 8, compressed data is read out successively from an optical disk device 6, and supplied to an arithmetic processing circuit 5. The arithmetic processing circuit 5 expands and decodes the received image data by an expanding/compressing part 51, and brings it to reverse quantization. Subsequently, a block constituting means separates only DC component data being the lowest frequency component from in each frequency component data in a frequency component separating part 53, and an image forming/block separating part 55 makes a reduced picture on a frame memory 4 by using only a DC component of each block. Next, a monitor 7 displays a multi-screen on this frame memory 4. In such a way, the file retrieval can be executed at a high speed without causing the deterioration of the compression efficiency.

CONSTITUTION:The titled steel products consists of 0.10-0.45% C, 0.01-0.35% Si, 0.3-2.0% Mn, <=0.020% P, <=0.010% S, 0.01-0.10% Al, 0.001-0.30% La, 0.0010-0.010% Ca, one or more among 0.1-3.0% Cr, 0.01-2.0% Mo, 0.01-0.20% each of Nb and V, 0.01-0.1% Ti, 0.0005-0.005% B, 0.15-0.60% Cu and 0.10- 0.60% Ni, and the balance Fe with inevitable impurities. La has said effect, yet less than the lower limit of La does not produce the effect, and more than the upper limit of La becomes uneconomical because La is an expensive element. Ca has said effect, and the lower limit or more of Ca is required to produce the effect, yet more than the upper limit of Ca increases the amount of inclusions contg. Ca and exerts unfavorable influence on the resistance to stress corrosion cracking due to sulfide.

Abstract: PROBLEM TO BE SOLVED: To prevent the blowout or a fire-preventive laminated glass plate caused by cracked gas at the time of the glass plate being exposed to high temperature by limiting the softening temperature of a filler filled in a clearance between the peripheral edge part of the fire-preventive laminated glass plate and a fitting groove of a frame body. SOLUTION: Two heat resisting transparent crystallized glass plates 10a are thermocompression-bonded through a fluororesin film 10b to form a fire- preventive laminated glass plate. A setting block 12 is arranged at a bottom part of a fitting groove 11a of a frame body 11, and the fire-preventive laminated glass plate 10 is placed thereon. An adhesive double coated tape of 3mm in thickness is used as a filler 14 in a clearance to an inner wall. The separating temperature of the fluororesin film 10b and glass plate 10a and the softening temperature of the filler 14 are set lower than the decomposing temperature of the fluororesin film 10b.  In case of being exposed to high temperature, the glass plate 10a is thereby separated before the fluororesin film 10b generates cracked gas, and the spacing of the glass plates 10a is enlarged by softening of the filler 14 so as to prevent the blowout of the glass plates 10a caused by cracked gas.
