Title: Production of cam shaft
Inventor: YAMASHITA JIRO
IPC: B22D13/02
Filed: 1985-12-05
Abstract: PURPOSE:To improve the quality of a product by rotating a casting mold formed with a hollow part for a cam shaft at a high speed, pouring a molten metal into the hollow part to form a solidified metallic layer and repeating such operation to form double-layered structure. CONSTITUTION:The hollow part 2 constituted of journal parts 3, cam lobe parts 4 and a shaft part 5 is provided to the casting mold 1 for centrifugal casting. While the casting mold 1 is rotated at a high speed, the molten metal 8 subjected to adjustment is poured into the mold and the 1st layer A in the state of sticking to each outside wall surface via centrifugal force is solidified by cooling. The other molten metal is poured in the same manner into the resulted space part 15 to form the 2nd layer B. Since the respective layers A, B are formed via the centrifugal force by the high-speed rotation, the defective joining between the layers is eliminated and sound casting is obtd. The quality of the product is thus improved by the above-mentioned method.

Title: Fixing structure of heat exchanger
Inventor: YAMADA ISAO
IPC: F28F9/00
Filed: 1996-10-16
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of heat exchange capacity without clogging a gap by performing a heat exchange between fluid flowing in a gap formed between a casing and a heat exchanger. SOLUTION: Between the inner wall of an air conditioning casing 1 and the outer wall on the laminating direction side of an evaporator 2, a gap 24 in which air flows is formed. The space distance t1 of this gap 24 is controlled so as to be a prescribed value by fitting (restraining) a projection part 23 and a recessed part 12a. By positively making air flow in the gap 24, a heat exchange is positively performed even on the outer wall of the evaporator 2 facing the gap 24 in addition to cooling of a core part and cooling of air is contrived. Therefore, heat exchange area of the evaporator 2 becomes larger as compared with that of the heat exchange performed by only the core part and cooling capacity of the evaporator 2 is improved.

Title: Device or method for detecting current
Inventor: TAKAHASHI TADASHI
IPC: G01R19/00
Filed: 1991-10-22
Abstract: PURPOSE:To obtain an insulation type current sensor being small in size and having high precision. CONSTITUTION:A sensor part is constructed by disposing a magnetoresistance effect element 2, a bias conductor 3 and a current conductor 4 on an insulating substrate 1. A change in the resistance of the magnetoresistance effect element 2 is inputted to an amplifier OP and a bias current (ib) is made to flow to the bias conductor 3 from the output Vo thereof. A magnetic field is generated when a current (i) is made to flow through the current conductor 4, and the resistance of the magnetoresistance effect element 2 is to change. Since the change in the resistance is fed back by the amplifier, however, the bias current (ib) is changed and the magnetic field of the magnetoresistance effect element 2 is controlled to be unvaried. Therefore, the hysteresis of the magnetoresistance effect element 2 and Barkhausen noise are not generated and thus execution of highly-precise insulation type current detection is enabled in a wide range.

Filed: 1987-10-31
Abstract: PURPOSE:To simplify the structure of an NC device by sending not only the DNC operation working information but the PC input/output control information for host computer to an NC control part from a communication control part via a bus. CONSTITUTION:A communication control part 4 performs transmission/reception of the PC input/output control information 14 for a host computer 1 to an NC control part 3 via a bus. The part 4 decodes the PC input/output control command received from the computer 1 and sends the information 14 to the part 3 via the bus. The part 3 receives the information 14 and gives a command to a PC control part 5 to set an input/output memory based on the contents of the information 14. Thus the part 5 changes the contents of the input/output memory. In such a constitution, no real wiring is needed for input/output signals between the part 4 and an input/output unit for the part 3. As a result, the structure of an NC device is simplified.

IPC: G05B9/02
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To efficiently incorporate the real time verification system in the remote operation system of highly reliable type by providing a keeping and delay mechanism of the remote operation command on the command side and the remote side. SOLUTION: Re-editing in processing inconveniences is performed referring to a command side keeping and delay mechanism 16, and the operation command in a remote side keeping and delay mechanism 18 which is not realized as a result of the re-editing is replaced by the new succeeding operation command. The operation command reaching the execution stage after elapse of the imaginary time delay on the command side is realized by transmitting the final execution command with the discrimination information of the operation command to the remote side. Thus, the time for collation and confirmation of transmission/reception of the remote operation command can be used as a part of or a whole of the imaginary time delay, and the real time verification and re-editing can be efficiently realized by the remote operation system of highly reliable type.
