Abstract: PURPOSE:To reduce the quantity of a quenching deformation, by applying deflection quenching varying the depth of a surface hardening layer gradually from the minimum to the maximum over its specified direction, to all pin parts and one journal part of a crankshaft. CONSTITUTION:When deflection quenching is applied to a crankshaft 10 for a four-cylinder engine carrying pin parts 11-14 and journal parts 21-25, overall pin parts 11-14 and journal parts 21-25 ranging from the bearing cylindrical part 30 and the successive curve forming part 31 to a fillet part 32 following the said part 31 are all treated with surface hardening. At this time, all pin parts 11-14 and one journal part 23 are treated with the deflection quenching, while uniform quenching is applied to other journal parts 21, 22 and 24. This deflection quenching, as to these pin parts 11-14 by way of example, becomes the minimum value at the side distant away from a center shaft of the crankshaft 10 so that they are carried out so as to have such a hardening layer in depth as turning to the maximum value at the central shaft side.

IPC: G06F9/22
Filed: 1983-09-28
Abstract: PURPOSE:To prevent a secondary fault caused by an erroneous data by providing a means for sending out a detecting signal, when a data of a memory address, whose access is not executed naturally, is read during a microprogram is under operation. CONSTITUTION:When a memory address of the outside of a range, which is loaded during a control program is under execution is used, for instance, as a work area, a microprocessor writes a prescribed data in its address first, and simultaneously, writes ''1'' in a check bit MC of its address.

Abstract: PURPOSE:To sharply write information and to easily read recording information by forming thin org. semiconductor films on the inside surface side of transparent film electrodes and disposing a liquid crystal and a conductor to be used as the other electrode on the inside thereof. CONSTITUTION:An optical recording medium is formed by forming the thin org. semiconductor films 1 on the inside surface side of the transparent film electrodes 2 and disposing the liquid crystal 3 and the conductor 4 to be used as the other electrode to the inside thereof. The films 1 generate electric conductivity or charge only in the parts where the light is cast by the irradiation of a laser beam. The conductor 4 forms the base electrode. The light strikes the films 1 through the electrodes 2 when the laser beam is irradiated to such optical recording medium. Such laser beam corresponds to the writing information. The electric conductivity or charge is generated in the film 1 in accordance with such information. The voltage impressed at the same instant acts on the liquid crystal through the parts of the film 1 where the electric conductivity or charge is generated. A crystal is generated in the liquid crystal 3 by such effect. The reading of the record is executed by using a laser pickup.

Title: Laser device
Inventor: YOSHIDA TOSHIO
IPC: H01S3/081
Filed: 1985-08-19
Abstract: PURPOSE:To enable a high-output and high-quality laser beam to be stably taken out into the atmosphere by disposing optical systems for dividing and synthesizing in time the laser beams in the inside and the out side of the housing of an oscillator. CONSTITUTION:The laser beam emitted from a laser exciting medium 2 is resonated by an instability type resonator comprising a concave mirror 3 and a convex mirror 4, and a laser beam 6 is taken out from a beam taking out mirror 5. By an internal chopper 11 this laser beam 6 is divided in time into laser beams 61 and 62, which penetrate through beam taking out windows 71 and 72 and are taken out into the atmosphere. The beams 61, 62 taken out are made to cross by planar mirrors 121, 122, and the beam 61 is reflected by an external chopper 13 so as to coincide with the propagation direction of the beam 62. Since the choppers 13 and 11 are adjusted in phase and synchronized, the beams 61 and 62 are synthesized in time into 63. A laser output two times the prior device can thus be obtained without lowering the laser beam quality.

Filed: 1986-07-31
Abstract: PURPOSE:To inhibit the data writing action during an unstable period without depending upon the host side by inhibiting the transmission of both read and index signals during the period needed for the positioning of a magnetic head. CONSTITUTION:The inverse input terminal set at one side of an inhibiting AND gate 25 which controls the transmission of the index signal is connected to the output terminal of an OR gate 24 together with the inverse input terminal of the other side of the gate 25 connected to an index detecting circuit 19. Thus the index signal is not outputted as it is, but outputted with limitation. While the inverse input terminal set at one side of an inhibiting AND gate 26 which controls the transmission of the read signal is connected to the gate 24 with the inverse input terminal of the other side of the gate 26 connected to a read/write circuit 13 respectively. Thus the read signal is not outputted as it is, but outputted with limination. In order words, the read signal G is transmitted simultaneously with the transmission of an index pulse F. Thus the inadvertent discontination of transmission of the signal G is avoided, therefore a write unable state is also avoided.
