Title: Height difference correction system for position measurement
Inventor: SHIMADA SATOSHI
IPC: G01C3/00
Filed: 1978-10-30
Abstract: PURPOSE:To decide the amount of correction of the height based on the distance measurements of before and after movement of the working machine by shifting the working machine vertically in a fixed distance. CONSTITUTION:Sea-bottom working machine 1 shifts in an action by distance r horizontally and distance Z vertically each. Now in case position A of transponder TA is higher than position C of machine 1, distance measurements la is set to the value measured when ultrasonic wave transmitter/receiver U is at position Ra and machine features the highest position. And the position of U at that time is defined as Ram. Then machine 1 is lowered down to the lowest position at position Ra, and then distance las up to TA is measured. The position of U at this moment is defined as Ras. Here the X-Y coordinates is considered with point Ras set as the original point and the segment connecting between points Ram and Ras set as the X axis each, and then Ram is set as (X3, 0) along with the position coordinates of TA set as (X4, Y4) respectively. As a result, distance la=Y4<2>+(X4-X3)<2> and las=X4<2>+Y4<2> are obtained, and accordingly the distance, i.e., the amount of correction is obtained through Eq. I between TA and correction position TA'.

Inventor: WATANABE TSUNEYA
IPC: G06F1/00
Filed: 1987-05-28
Abstract: PURPOSE:To accurately detect the runaway of a microcomputer and to surely prevent this runaway by using a 1st resetting means which applies a resetting signal to the microcomputer after detecting that no pulse is generated from an output port and a 2nd resetting means which resets the microcomputer after detecting that a fixed number of pulses are outputted. CONSTITUTION:A 1st resetting means A consists of a D type flip-flop 5 connected to a reset terminal R via a NOR gate 24, a NOR gate 8, etc. While a 2nd resetting means B consists of D type flip-flops 18-22, etc. Thus it is judged that an MPU1 has the normal working only when the only pulse 20 is outputted from an output port PO of the MPU1 in a fixed cycle. Then the runaway of the MPU1 is decided when >=2 pulses are outputted from the port OP of the MPU1 in any case the port PO is fixed at an H or L level. Then the MPU1 is reset so that the runaway of the MPU1 can be surely avoided.

Title: Metal gasket
Inventor: SATO MASANAO
IPC: F02F11/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To make a device correspond to change in a fastening surface pressure distribution, and make the device correspond to a design of the fastening surface pressure distribution by sticking a covered layer so as to set a difference between a fastening surface pressure of an adjacent part and a fastening surface pressure of a grommet part to a prescribed surface pressure. SOLUTION: In a metal gasket, a covered layer 4 having a suitable thickness is stuck on an adjacent part A, and thereby, a difference of fastening surface pressure between a grommet par 3 and the adjacent part A can be set to a surface pressure in a desired fastening surface distribution. In this time, desired fastening surface pressure is ensured on a fastening surface pressure of an opening 2 circumferential edge by the grommet part 3. Since the covered layer 4 is formed of a high hard film forming material, the surface pressure difference is simply converted into a thickness difference between a metallic thin plate 1 and the covered layer 4, and a gasket corresponding to the surface pressure difference in a desired fastening surface pressure distribution can be manufactured simply and surely.  Even in the case where correction of the fastening surface pressure distribution is necessitated and a design of the gasket is changed, correspondence is carried out by changing the thickness of the covered layer 4.

     CONSTITUTION: The rolling mill oil being pumped up from the rolling mill oil tank 6 by the pump 7 is passed through the filter 8 to removed the sludge included, and is sprayed from the spray nozzle 10 against the material 9 and the work roll 5. The material 9 and the work roll 5 are quickly cooled and are kept at -20W20°C. The rolling mill oil is collected into the oil pan 15 and returned to the tank 6 through the tubing 11. Meanwhile, the rolling mill oil held in the tank 6 is sent by the recycling pump 14 to the heat exchanger 12 in order to exchange its heat with the refrigerant being cooled to a low temperature by the refrigerator 13; consequently, the rolling mill oil at such low temperatures as -20W20°C returns the tank 6. According to this method, the Vickers hardness of the rolled material is improved by 10W20% as compared with that of the rolled material depending on the conventional rolling method.

Abstract: PURPOSE:To detect the damage state or the like of an optical fiber faster at a high sensitivity, by applying an ultrasonic vibration near the incident end of the optical fiber to detect the reflected wave from the end face, a breakage point or the like. CONSTITUTION:A laser light 10 from a laser oscillator 8 is focused with a lens 9 to be incident into an optical fiber 1. A burst signal generated with an ultrasonic wave oscillator 3 is applied to a ceramic piezo-electric element 2 and converted into a mechanical vibration to be applied to the optical fiber 1. An ultrasonic vibration propagating through the optical fiber 1 is reflected on the end face or at a defect point to be detected with the piezo-electric element 2. An electrical signal from the piezo-electric element 2 is amplified with a preamplifier 4 and the noise portion thereof is attenuated with a filter 5 to be applied to a waveform recognition/comparator circuit 6. If any defect such as breakage takes place in the optical fiber, the reflected wave at the defect point will be observed or the reflected wave from both the incidence and reflection side end faces fail to be observed. Then, when the reflected wave from the defect point is recognized, an oscillation stop signal is sent to a laser control section 7 to stop the laser oscillation.
