Title: Magnetogrinding method
Inventor: TSUCHIYA KAZUHIRO
IPC: B24B37/00
Filed: 1991-08-21
Abstract: PURPOSE:To miniaturize a gringing attachment as well as to automate a grinding process by applying an abrasive grain, hardened with oil wax or the like, on a workpiece surface, and filling up a ferromagnetic grain in a gap between a permanent magnet and a workpiece, separately from the abrasive grain, in a magnetogrinding method by means of a numerically controlled machine tool. CONSTITUTION:An abrasive grain 6 covered with paraffin wax 7 is applied to the circumference of a cylindrical workpiece 2. In addition, a ferromagnetic grain 3 of about 100mum-500mum in ferrite grain size is filled up in a gap between a permanent magnet 1 and the workpiece 2. Then, the workpiece 2 is rotated and rocked in the axial direction, thus it is ground by means of magnetogrinding. With this constitution, paraffin is melted by frictional heating, and the abrasive grain 6 is stuck to an outer circumferential part of the ferromagnetic grain 3, through which a surface of the workpiece 2 is ground.

Title: Photographic film cartridge
Inventor: ITO TOMIO
IPC: G03C3/00
Filed: 1995-08-17
Abstract: PROBLEM TO BE SOLVED: To stabilize quality by surely preventing the increase of the pulling out force of a photographic film and a deterioration in the property of shielding light, in a mass-produced photographic film cartridge. SOLUTION: For stabilizing the quality of the photographic film cartridge, the clearance between the outer periphery of a spool 5 and the openings 11 of caps 10 is maintained with high accuracy. Projected lines 15 are formed between the spool through-openings 11 and bent parts for fitting, in the caps 10 fitted on both ends of a shell plate 3. Even if great force is exerted on the bent parts of the caps 10, at the time of fitting the caps 10 on the shell plate 3, the stress deformation is absorbed by the projected lines 15, not to be exerted on the openings 11. The inside diameters and shapes of the openings 11 can be hardly changed before and after the caps 10 are fitted on the shell plate 3, so that the clearance can be stably kept.

Abstract: PROBLEM TO BE SOLVED: To suppress increase in a brake cylinder hydraulic pressure by reducing supply of electric energy to a solenoid supply control valve for controlling the solenoid supply control valve in the hydraulic fluid supply reducing direction when a vehicle carrying a brake device is in a stopping state. SOLUTION: A holding valve 100 is arranged in the middle of a branch passage 68 and magnetically excited into a closed condition so as to prevent flow of hydraulic fluid directed from a brake cylinder 56 to a master cylinder 14, so that a cylinder hydraulic pressure is maintained. In the branch passage 68, a reservoir passage 106 is extended from the part between the holding valve 100 and the brake cylinder 56 so as to reach a reservoir 108. In the middle of the reservoir passage 106, the pressure reducing valve 110 of a normally- closed solenoid selector valve is arranged. When the pressure reducing valve 110 is magnetically excited to be opened, hydraulic fluid directed from the brake cylinder 56 to the reservoir 108 flows and a brake cylinder hydraulic pressure is reduced.

IPC: B22C5/18
Filed: 1990-08-10
Abstract: PURPOSE: To enable the reconditioning and recycling of used green sand by drying and calcining the green sand to evaporate org. matter, then mechanically separating clay and further reacting the green sand with an aq. acid soln. to free the clay. CONSTITUTION: The used green sand regulated in grain sizes is sent to a drying/sizing device 6 where the moisture is reduced to zero and the clay is made to soar up from a sand bed 8. The separated sand is sent from a hopper 10 to a fluidized bed type thermal calcining machine 14 where the temp. of the sand is elevated and an org. binder is removed. The calcined sand is dropped onto a cooling/separating device 30 to separate the clay. The sand is then released into a bombardment chamber 38 where the bonding of the sand and the clay is destroyed. The sand from which the clay particles are removed is transferred to a surge hopper, is metered and is sent to a mixer 48. Simultaneously the aq. acid soln. is poured by a metering pump 50 into the same and is mixed therewith, by which the clay particles are separated.  The sand regulated in pH is fluidized in the drying/sizing device 56 to have clay particles captured in an air passage pipe 60. As a result, the dry sand which does not contain the clay and is regulated in the pH is obtd.

Filed: 1991-08-22
Abstract: PURPOSE:To hold storage information in a memory even when an internal battery cannot supply power required for holding information in the volatile memory and to use it in the same way as time before a power cut when commercial power is restored by reading the content of the volatile memory and storing it in a medium recording device at the time of the power cut. CONSTITUTION:When a power cut detection circuit 15 detects the power cut of commercial power, a power cut detection signal is transmitted to CPU 10 and a power source part 16. When the power source part 16 receives the power cut detection signal from the power cut detection circuit 15, it switches power supplied to respective devices to an internal battery 17, CPU 10 immediately reads data stored in the volatile memory 11 and outputs it to a DTMF generator 13. It converts inputted storage data in the volatile memory 11 from a digital signal into an analog signal and outputs it to a tape recording/reproducing circuit 12. When commercial power is restored, data read from the tape recording/reproducing circuit 12 is converted into the digital signal by a DTMF receiver 14 and is rewritten into the memory 11.

Abstract: PURPOSE:To hold an invariably constant display screen position by detecting the time from a horizontal synchronizing signal to a video signal, storing the minimum time, and varying the delay time of the horizontal synchronizing signal in a horizontal position control circuit according to the stored value. CONSTITUTION:The horizontal synchronizing signal HS and video signal VS are inputted to a time measuring circuit 6 and the time between both signals HS and VS is measured. his measured time C is compared 7 with the initially set time T in a minimum time register 8 and shorter time is written in the register 8.
