Patent JP-S6271252-A (JP)
Title: Lead frame and semiconductor device using the same
Inventor: OKIKAWA SUSUMU
IPC: H01L23/495
Filed: 1985-09-25
Abstract: PURPOSE:To prevent the pellet of a semiconductor device from cracking by using a lead frame in which a stress alleviating portion is formed inside from a locking unit by forming the locking unit in a tab hanging lead. CONSTITUTION:Since through-holes 5 are formed in a tab 3 and a tab handing lead 4, resin 11 is fed into the holes 5 when a package is molded to completely stop moving the lead 4. Thus, the bonding of the lead 4 to the package resin 11 is extremely strengthened. A circular-arc portion 8 is formed at the connecting portion of the tab 3 to the lead 4 to increase the width of the connecting portion. Since the width of the connecting portion is thus wide, the stress can be that much dispersed with the result of effectively preventing a pellet from cracking due to the stress concentration.

Title: Zero-phase current measuring device
Inventor: TSUNODA TAKANORI
IPC: G01R29/16
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To make accurate detection by providing signal input sections with different measuring ranges for individual phases, and obtaining the zero-phase current with the outputs of the other input sections when the overflow of the output of an input section with a small range is detected. SOLUTION: Current transformers CT1-CT3 connected in series to the primary side windings are connected to three phases respectively, and individual secondary winding outputs are inputted to operation amplifiers op1-op6 with the same characteristic such as gain. The number of the secondary windings is set so that the measuring ranges of the signal input sections constituted of the CT1-CT3 and op1-op6 are made the 5 A-range of the stationary current measuring range and the 100 A-range of the accident current measuring range for individual phases. An overflow judgment section 4 invariably monitors the signals Ias , Ibs , Ics of the 5 A-range, judges the input signals as the overflow state when one or more signals exceed a fixed level, and switches a switch 5 from the normal contact S side to the O side.  An I0 calculation section 6 calculates the zero-phase current I0 based on the signals Iao , Ibo , Ico of the 100 A-range.

Title: Gas turbine combustor
Inventor: SASAKI MASASHI
IPC: F23R3/60
Filed: 1989-08-15
Abstract: PURPOSE:To obtain high durability even if heat load is repeated by arranging a shielding cylinder in the inside of a ceramic inner cylinder of a combustor, and inserting a flange projected on the outer periphery of the shielding cylinder to an inner cylinder into the ceramic inner cylinder to support while dividing the shielding cylinder into a plurality of sections along a shaft center line. CONSTITUTION:A shielding cylinder 5 of high heat resistance is located in the inside of an inner cylinder 2 made of ceramic. As the result, a radiation heat transfer quantity to the inner cylinder 2 can be reduced remarkably to effectively control local temperature increase of the inner cylinder 2 so as to protect the ceramic-made inner cylinder 2 from cracks, failure and the like. Since the shielding cylinder 5 is formed of monolith ceramic, or ceramic fiber- contained composite ceramic and the like, and axially divided into a plurality of section is the plane including air holes 8, concentration of thermal stress can be eased even if radiation heat is received to make it high temperature. Thereby it is far superior in thermal durability, compared with the ceramic-made inner cylinder 2 whose circumference is formed integrally, and there is nothing to fear of failure even if high temperature heat is directly received by radiation.

Title: Method of supplying inert gas to phosphoric acid type fuel cell
Inventor: ISHIKAWA AKIRA
IPC: H01M8/04
Filed: 1984-10-08
Abstract: PURPOSE:To prevent the deterioration of cell performance by monitoring moisture in inert gas supplied to a cell, and restraining the moisture in the gas to given amount after the total amount of reaction gas is substituted with the inert gas. CONSTITUTION:When the supply starting command of inert gas N is generated from a command device 80, the inert gas N flows into both reaction gas sections of a cell 10 to substitute with the reaction gas, while gradually expelling the reaction gas. And a trap 22 within the source of inert gas starts to function, and thus the gas N which does not contain moisture will pass through a sampling chamber 31, and the monitoring of quality for the gas N is started by a moisture meter 32 etc. And after the approximately total amount of the gas N within the cell is substituted with the inert gas N, the moisture in the gas N to be supplied is restrained under 0.1wt%, preferably under 100ppm. Whereby, it is possible to prevent the deterioration of cell performance.

Title: Servo motor controller
Inventor: YAGAWA KEN
IPC: H02P29/00
Filed: 1987-08-27
Abstract: PURPOSE:To rotate a servo motor in a command rpm, by automatically compensating the offset voltage generating intrinsically in a control device of the motor. CONSTITUTION:In a speed operation section 6 the positional deviation or speed command pulse of a driven body calculated by a deviation calculation section 5 is inputted through a position-speed command calculation section 7 and a speed command is outputted to a D/A conversion section 8. The D/A conversion section 8 converts this speed command into analogue data (voltage), which will be supplied to a servo motor 1 through a servo amplifier 9. The servo motor 1 then rotates in specified rpm. At a position differentiation section 10 the actual speed of the servo motor 1 is calculated and outputted into a corrected value calculation section 11. The corrected value calculation section 11 outputs the difference between the speed command and the actual speed as a corrected value into the speed operation section 6. In this way, since the corrected value outputted from the corrected value calculation section 11 corrects the offset voltage that generates intrinsically with the D/A conversion section 8 and the servo amplifier 9, the servo motor 1 will be caused to rotate in accurate revolutions.
