Title: Casting method
Inventor: FUKUI HIROYUKI
IPC: B22D18/04
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To enable casting of a good product without executing a testing injection at the time of starting a casting device by once returning back into a closed vessel after pushing up molten metal to a molten metal supplying hole by a preset time to preheat a sprue, etc., in a metallic mold, at the time of pouring the first molten metal after supplying the molten metal into the closed vessel. SOLUTION: In pouring the first molten metal after supplying the molten metal 2 into a furnace body 3 composed of the closed vessel, a pressurizing device 5 starts the pressurization with a control device 6 and also, the molten metal temp. is raised by the preset temp. The molten metal 2 in the furnace 3 is pushed up to the molten metal supplying hole 13c through a molten metal supplying tube 11 with the pressurization. The pressurizing device 5 holds the condition, in which the surface of the molten metal 2 reaches the molten metal feeding hole 13c, by the preset time. At this time, the lower metallic mold 13, a sprue cup holding member 13b, sprue cup 15, etc., are further heated with the heat of the molten metal 2.  Thereafter, the pressurizing device 5 stops the pressurization and the pressure in the furnace 3 is lowered to return back the molten metal 2 pushed up in the molten metal feeding tube 11, into a crucible 7.

Title: Length measuring apparatus
Inventor: SAKAMOTO NAOSHI
IPC: G01B9/02
Filed: 1987-08-31
Abstract: PURPOSE:To enable highly accurate measurement of length, by irradiating reflecting surfaces of a second reflection film with several monochromatic luminous fluxes to detect interferring lights from the reflecting surfaces with separate photo detectors. CONSTITUTION:A polarization mechanism 7 of a length measuring apparatus is made up of a first prism 71 which polarizes a luminous flux P1 to be turned to a luminous flux parallel with a luminous flux P2 and a second prism 72 which polarizes a luminous flux P3 to be turned to a luminous flux parallel with the luminous flux P2, which makes optical paths of outputs from a diffraction grating section 6, namely, the luminous fluxes P1, P2 and P3 parallel with each other. The luminous flux P1 irradiates a reflecting surface 8a, the luminous flux P2 a reflecting surface 8b, and the luminous flux P3 a reflecting surface 8c separately; and interferring lights thereof are sent to a polaroid prism 21 through a lambda/4 plate 22. In this case, as the luminous fluxes P1, P2 and P3 are made incident independently, this eliminates judgement of the size of a dark peak value, thereby enabling highly accurate measurement of length.

Title: Control device for allocation of driving force for four-wheel drive vehicle
Inventor: MATSUDA TOSHIRO
IPC: B60K17/348
Filed: 1988-08-31
Abstract: PURPOSE:To allocate the magnitude of engine brake into the side of front wheels and the side of rear wheels, and thereby secure the safety of a vehicle in running stability by estimating the magnitude of engine brake by an engine brake magnitude estimating means, and thereby determining a allocation ration of driving force of the front wheels to the rear wheel to the rear wheels by means of a driving force allocation ratio setting means. CONSTITUTION:The magnitude of engine brake acting on a vehicle is estimated by an engine brake magnitude estimating means, and a driving force allocation ratio of the side of front wheels to the side of rear wheels is determined based on the estimated value of engine brake, engine brake is thereby prevented from being applied only to either one of the front wheels and the rear wheels so as to be allocated to the front and rear wheels so that the safety of a vehicle is secured in running stability. In addition, the condition of vehicle speed reduction detected by a reduces speed condition detecting means, as a result, the magnitude of engine brake is allocated to the front and rear wheels under the reduced speed condition, the front wheels are not thereby synchronized with the rear wheels so that excellent anti-skid control is executed. This constitution enables unstable behavior caused by engine brake at the time of reducing vehicle speeds to be positively prevented, thereby enabling control stability to be improved.

Title: Controlling circuit of microprocessor bus
Inventor: TAKASHIMA HIROSHI
IPC: G06F13/366
Filed: 1982-12-14
Abstract: PURPOSE:To use a data transfer requesting line and a data transfer permitting line in common to reduce the number of signal lines by assigning individual numbers to plural peripheral circuits respectively. CONSTITUTION:A scanning circuit 1 usually sends the numbers of plural peripheral circuits successively and circularly, but if a data transfer request is sent from any one of the peripheral circuits 13, stops scanning and continues to send the number of the peripheral circuit 13 concerned for a fixed period. Since the data transfer requesting line 4 and the data transfer permitting line 5 are connected to the scanning circuit 1 through an NOR circuit 2, the stop of scanning is continued during the sending of a data transfer permitting signal. Therefore, when the peripheral circuit numbers are successively sent from the scanning circuit 1, only the peripheral circuit 13 finding the coincidence of the number assigned to itself with the sent number can transmit/receive the data transfer request signal and the data transfer permitting signal through the 1st and 2nd gates 12, 11.

Abstract: PURPOSE:To set a span amount without necessitating skill, by a method wherein constants are obtained from two signals from a detecting means made to correspond to a reference length and zero setting, signals from the detecting means made to correspond to a substance to be measured are multiplied by the constants and thereby a measured value is obtained. CONSTITUTION:Monitoring a detected value display unit 10, a measurer makes a detecting means 2 positioned at a mechanical zero and the means 2 delivers a signal at this time to a variable-gain amplifier 4. The amplifier 4 amplifies the signal from the means 2 by a specified sequential multiplication rate and sends it to an A/D converter 5. The converter 5 subjects the signal to A/D conversion in the sequence of input and sends it to a temporary zero storage element 13. The means 2 being used, subsequently, the dimensions of a block gage of which the reference dimensions are known are inputted to a span amount setting element 7. A subtracter 14 subtracts a temporary zero value stored in the storage element 13 from a signal relating to the block gage and sends the result to a constant calculating element 8. The setting element 7 stores values relating to the reference dimensions in a span storage element 16. When the result of subtraction is sent to the calculating element 8 herein, prescribed computation is executed in a controller 12.

IPC: B29C45/72
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To heat injection resin with good accuracy while resin is flowed. SOLUTION: The heating current value of an infrared ray heater is increased before the start of injection, and then a shutter 12 is opened upward by an air cylinder 13, and infrared rays are started in the given wave forms before the injection of resin, passed through an infrared ray permeable member 6c and emitted to a molding cavity C.

Title: Internal gear
Inventor: ISHIKAWA KATSUNORI
IPC: F04C2/10
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To restrain an increase in leakage of discharge fluid in discharge passage recesses of a case and a cover in order to improve a pump efficiency by forming the recesses radially outer than a receiving recess, and forming a communication means communicating a discharge area with a discharge passage into a tunneled through hole. SOLUTION: When an internal gear 2 and an external gear 3 are rotated with the rotation of a drive shaft 6, such a pumping action is performed that fluid is taken in from an intake passage 26 and discharged to a discharge passage 25. Part of the fluid discharged is discharged to the passage 25 via tunneled through holes 15, 24 from each of discharge port recesses 7, 20. In the vicinity of the discharge part of the gear 2, the outer peripheral surface of the gear 2 is not exposed to discharge passage recesses 12, 22. Accordingly, such a case is prevented that the discharge pressure acts on the outer periphery of the gear 2 to push the gear 2 to the diametrical direction. Namely, a seal gap at a tooth top of each of gears 2, 3 becomes large to solve a problem of an increase in leakage of discharge fluid to the intake side, resulting in the provision of a high efficiency pump.
