Title: High carbon-chromium bearing steel
Inventor: HYODO TOSHIAKI
IPC: C22C38/18
Filed: 1988-04-05
Abstract: PURPOSE:To prolong rolling contact fatigue life even under severe conditions by specifying respective contents of C, Si, and Cr in a high-carbon chromium- type bearing steel with a specific composition to improve hardness and tempering softening resistance. CONSTITUTION:This high-carbon chromium-type bearing steel has a composition consisting of, by weight, 1.1-1.5% C, 1.0-2.0% Si, 0.7-1.3% Cr, 0.2-1.0% Mn, and the balance Fe. In this steel, hardness can be improved by increasing C content to increase the amount of carbide in a matrix, but spheroidizing of carbide becomes difficult when Co content exceeds the upper limit. As to Si content, an effect of improving deformation resistance under high load cannot be produced when it is below the lower limit and, on the other hand, cold workability is deteriorated when it exceeds the upper limit. Moreover, the control of heat treatment conditions is made difficult because of deterioration in hardenability and reduction in residual carbide when Cr content is below the lower limit, and further, since carbide is liable to occur and macrocrystalline carbide is formed because of increased C content and, as a result, service life is shortened when Cr content exceeds 1.3%, the upper limit of Cr content is regulated to 1.3%.

Title: Power source stabilizing device
Inventor: OGAMI TOMOYA
IPC: G05F1/56
Filed: 1995-03-17
Abstract: PURPOSE: To reduce electric power loss and heat generation in a power transistor(TR) by switching the power TR by a PWM system and cutting off a peak current at the time of a maximum AC voltage. CONSTITUTION: The power TR 7 is applied with a voltage and a current obtained by rectifying an AC voltage. The input voltage is inputted to one terminal of a comparing circuit 11 and the output voltage from an error detecting circuit 10 is inputted to another terminal of the comparing circuit 11. The comparing circuit 11 discriminates only the voltage which is inputted from a rectifying circuit 6 and higher than the voltage inputted from the error detecting circuit 10. A pulse generating circuit 12 generates a pulse waveform with the voltage discriminated by the comparing circuit 11. An inverting circuit 13 inverts this pulse waveform to generate a pulse voltage for controlling the power TR 7. Consequently, when the input AC voltage is maximum, the power TR 7 is turned OFF to cut off the peak current.

Abstract: PURPOSE:To make it unnecessary for the operator of an article conveyor to remove articles from a first conveyance passage when the operator resumes the operation of the conveyor, by providing a mechanism which removes the articles from the first conveyance passage when other articles going aead of the former aritlces have jammed due to the wrong action of a reloading transfer means. CONSTITUTION:When a sheaf of sheets conveyed on a passage 2 have jammed thereon due to the wrong action of gates 4, 5 or sheaf push-out means 6, 7, it is found out by a jam detector. At that time, a timing cell finds out that the sheaf of sheets have come to a color detector 3, to operate a solenoid driver to close the conveyance passage 2 by a gate 31. As a result, another sheaf of sheets following the former sheaf of sheets are introduced into a reject conveyance passage 32 by the gate 31 and then piled up in a reject pile-up section 24 through the passage 32. After the jammed sheaf of sheets are removed from the conveyance passage 2, the gate 31 is turned to open the passage.

Abstract: PURPOSE:To effectively use an unused area and to prolong the life of a flash type EEPROM by confirming the contents of a register with a control means when erase-write to the flash type EEPROM is instructed and performing the write when a cell is judged to be in a writable state. CONSTITUTION:When the control means 3 receives the instruction of the erase- write, the means 3 refers to the register 8 corresponding to a sector in the flash type EEPROM 4. When no flag stands on all bits of the register 8, the data are written in the sector no flag stands. When the flags stand on all bits, control is moved to a next sector. When the flags stand on all bits of a final cell, after the control is moved to the top cell, the erase-write is executed. Thus, the area in the cell is used effectively, and the life of the ROM 4 is prolonged.
