Title: Data rewriting preventing circuit for on-vehicle control device
Inventor: ASAI HIRONORI
IPC: B60R25/04
Filed: 1995-03-24
Abstract: PURPOSE: To prevent unauthorized rewriting of data by outputting a cover open detection signal from a cover open detecting part to a data monitoring art when a cover of a case is opened, and erasing data from a memory on a board of an on-vehicle control device by the data monitoring part based upon the input of the detection signal. CONSTITUTION: When a scew 12 is removed in order to detach the cover from the case, a contact chip (11) part is electrically cut off. When voltage is impressed to the base of a transistor(TR) 13, the TR 13 is turned on and the collector side of the TR 13 is turned to a low level. An inverter 16a inverts its level and outputs a reset signal to the reset terminal of an R/S flip flop circuit 16. At the time of inputting the reset signal, the circuit 16 inverts the level of a Q' output signal to a high level and outputs the inverted signal to a RAM 19 to erase the data. Thus data can be prevented from unauthorized rewriting.

Title: Double hetero junction type semiconductor laser
Inventor: HAMADA HIROYOSHI
IPC: H01S5/10
Filed: 1982-04-19
Abstract: PURPOSE:To reduce the amount of spontaneous light emission by a method wherein the carrier density of a P type clad layer is set over the fixed value, in a double hetero junction type semiconductor laser equipped with the P type and an N type clad layers respectively by sandwiching an active layer. CONSTITUTION:The double hetero junction type semiconductor laser is equipped with the N type clad layer 2 and the P type clad layer 4 by sandwiching the active layer 3. The both clad layers 2 and 4 have energy band gaps wider than that of the active layer 3, and the light refractive index is set small. In such a semiconductor laser, the relation between the carrier density of the P type clad layer and the amount of spontaneous light emission is when the carrier density becomes 10<18>/cm<3> or more, the amount of spontaneous light emission decreases rapidly. Therefore, the amount of spontaneous light emission can be reduced by selectively the carrier concentration in such a manner.

Abstract: PURPOSE: To suppress a change in load on an electric power source unit to a minimum by changing the electric power circuit of the main part of a unit over to a dummy load when a revolving magnetic field is not generated.  
     CONSTITUTION: While access from CPU is not attained, the switch of current change-over circuit 6 is connected to dummy circuit 5 set to the same degree as the power consumption of revolving-magnetic-field generating circuit 2 and almost all of the electric power of power circuit 1 is consumed. Next, when the access is attained, magnetic-field generating circuit 2 is driven by logic circuit 4 and the switch of change-over circuit 6 is changed over to connect electric power unit 1 to magnetic-field generating circuit 2. On the end of data transfer, the switch of change-over circuit 6 is changed over to connect electric power unit 1 to dummy circuit 5 again. Thus, a change in load on electric power unit 1 can be minimized. In addition to magnetic-field generating circuit 2, the main part of logic circuit 4, etc., is similarly changed over to make it possible to improve the effect further.

Title: Recovery device for duplexed disk
Inventor: MATSUMURA YOSHIHIDE
IPC: G06F3/06
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To speed up the restoring process of a duplexed disk device which is performed after the unexpected restart-up of the system. SOLUTION: A program executed by a CPU 100 can access a nonvolatile memory 300 and disk devices 401-40n through a system bus 200. On the nonvolatile memory 300, there are disk device write information storage areas 301-30n corresponding to the disk devices 401-40n. Those areas are updated when requests to write the corresponding disk devices are made. For the restoring process of duplexed disk devices, the CPU 100 refers to the areas and restores only matched blocks. Consequently, the actual I/O to and from the disk devices for the restoring process is limited to the matched blocks, so the process is speeded up.

The steel is excellent in weldability because of its low carbon equivalent but low in toughness. To improve the defect, the steel ingot is first hot rolled in the gamma recrystallization zone at more than 1000°C so that the gamma grain size becomes a gamma particle number of more than (-2 + 170 Nb %). Afterwards, it is subject to a more than 30% drafting in a temperature range from Ar 3  to 900°C during air cooling and then to a gamma-alpha transformation at a 5 to 60% transformation rate, followed by a transformation zone-rolling at a draft of 10 to 60%. The heating treatment after rolling is made by coiling it at a temperature below the Ar 1  point or cooling it with air. The treatment can confer excellent toughness upon steel even at low carbon equivalent.

Abstract: PURPOSE:To reduce the size and weight of a magnetic disk and to improve the magnetic recording density by specifying the percentages of Al, Cu, Mg, Zn and inevitable impurities contained in an Al alloy so as to increase the strength. CONSTITUTION:This Al alloy consists of, by weight, 0.3-2.0% Cu, 3.0-5.0% Mg, 0.5-3.0% Zn and the balance Al with inevitable impurities including <=0.10% Si, <=0.10% Fe, <=0.01% Mn, <=0.01% Cr, <=0.01% Ni and <=0.01% Ti. Cu, Mg and Zn can remarkably increase the hardness and strength of the alloy, and Si, Fe, Mn,Cr, Ni and Ti as inevitable impurities each form an intermetallic compound. Since the Al alloy having said composition has high hardness, when it is used as the material of the substrate of a magnetic disk, the surface can be converted into a much superior mirror finished surface by buffing in a relatively short time. Intermetallic compounds present in the matrix are fine and uniform, and nonmetallic inclusions have been removed by filtering molten metal or by other means, so the thickness of a magnetic recording medium can be reduced.
