Title: Handwriting input device
IPC: G06F3/0488
Filed: 1992-04-03
Abstract: PURPOSE:To freely vary thickness of a line by writing pressure of a pen by detecting pressure from the pen applied to an input panel, varying width of a line or size of a point in a graphic in accordance with magnitude of this pressure and displaying it on a display. CONSTITUTION:When an input pen 11 is brought into contact with an input panel 6, a constant-current outputted from the input pen 11 is converted to an analog signal of coordinate data by each operational amplifier 13 of an input coordinate detecting part 7 and a writing pressure detecting part. Also, a voltage detected by each piezoelectric element 12 due to contact is detected by each operational amplifier 13' and converted to an analog signal of writing pressure data. Those data are converted to digital data and transferred to a CPU. The CPU derives a center position of the input pen 11 from the digital coordinate data, and also, derives writing pressure by adding digital writing pressure data, calculates a center position of dots on a liquid crystal display and the number of dots, that is, line width from these values, and controls the liquid crystal display.

Title: Spinning forming device
Inventor: SAITOU MASAMI
IPC: B21D22/14
Filed: 1981-05-29
Abstract: PURPOSE:To obtain a spinning device that manufactures very fine and thin nozzles or tubes economically by providing a mechanism that sets accuracy of roller shifting and initial clearance between rollers in a spinning device. CONSTITUTION:This spinning device is provided with a lead screw 23 driven by single driving source 21 and a pair of rollers 8, 8 that moves in the direction of changing the distance by the screw 23. When a small load, for instance a weight 41 is placed on a reference spacer 38 opposed to rollers 8, 8, the spacer 38 is locked between the rollers 8, 8. When a larger load, for instance a weight 40, is placed, the spacer 38 is inserted between rollers 8, 8. At this time, a reference point can be set by absorbing elastic characteristics of the roller supporting system such as roller axes 9, slide stands 30, 31 etc. Accordingly, the reference point can be recognized as zero point, and a pulse motor driving circuit 46 can be controlled by a zero point recognizing circuit 44. Consequently, accuracy of roller shifting can be maintained at + or -1mum, and very fine and thin nozzles or tubes can be manufactured economically.

Title: Optical disk controller
Inventor: TAMAI YOSHIAKI
IPC: G11B7/00
Filed: 1987-04-02
Abstract: PURPOSE:To immediately transfer information to a host device, by using an alternate information buffer, and transferring the information of the alternate sector of a buffer when a request to transfer the information of the alternate sector is issued. CONSTITUTION:When an instruction to read the information of designated track number and sector number from the host device is issued by a processor 7 via an interface 3, a disk 1 sends read information to a demodulation circuit 2. The processor 7 reads an ID part at a circuit 4, and compares the track number and the sector number with those in a RAM 9. When no coincidence is obtained, the read information is passed to a demodulation circuit 6 and an error correction/detection circuit 5, and sends the information 30 of an information part 33 from a transfer circuit 10 to the host device. When the coincidence is obtained, it means that the read information is incorrect, then, the processor 7 makes a control circuit 6 read the information of the alternate sector in the buffer 8 by issuing the instruction to a corresponding sector, and makes the circuit send the information to the transfer circuit 10. The circuit 10 sends the information 30 of the information part 33 of the alternate sector to the host device by switching a bus by the processor 7. Thereby, no seek time or rotation waiting time is required, and the information of the alternate sector can be transferred immediately.

Title: Oil seal of dry type multi-plate clutch
Inventor: OOISHI AKIFUMI
IPC: F16J15/32
Filed: 1979-06-30
Abstract: PURPOSE: To procure an effective sealing by excavating a hollow in the top part of a nut which is to fasten the clutch boss in engagement by thread with the clutch shaft at its end and filling this hollow with a sealing material which is to fill out the gap between a push rod and the hollow wall.  
     CONSTITUTION: A dry type multi-plate clutch has usually such a construction that a clutch plate 11 and a friction plate 13 are joined when a spring 15 pushes a pressure plate 14 and the rotation of an intermediate shaft 2 is thereby transmitted to the clutch shaft 16. The clutch is disengaged when push rods 19, 18 travel to the right through revolution of a pushing member 26 and the abovementioned pressure plate 14 travels consequently to the right against the force applied by the spring 15. A hollow 23 is excavated in the top part of a nut 21 which is to be engaged by thread with the clutch shaft 16 and this hollow 23 is filled with a sealing material 24. This sealing material is filled in the gap between the surface of the push rod 18 and the wall of the hollow 23 and prevents thus surely the oil in the crank case 1 from leaking out to the clutch part.

Title: Metering device for powder and granule
Inventor: SEO YUUZOU
IPC: G01F11/28
Filed: 1980-06-19
Abstract: PURPOSE:To make accurate metering of powder and granules possible by providing a valve having such apparent specific gravity capable of floating the valve on the powder and granules in a  fluid state on the lower side of an exhaust port provided in the upper part of a metering vessel  and preventing the discharging of the powder and granules. CONSTITUTION:A solenoid valve 11 is opened and the powder and granules in a hopper are fluidized by highly pressurized gas and are introduced via a packing route 7 into a metering vessel 2 from near its top and end in its tangential direction. Right after the start of packing, the powder and granules are introduced in a manner as to rotate along the inside wall, and only the gas is exhausted from an exhaust port 13. When the height of the powder and granules in the vessel rise and arrive at the height of a lightweight spherical valve body 20 consisting of a hollow rubber ball, surface-treated foamed polyethylene or the like, the valve body 20 ascends by receiving the buoyance from the powder and granules in a fluid state, thereby closing a valve seat 23. When the inflow of the gas is hampered, the valve 11 is closed. A solenoid valve 12 is then opened to fluidize the powder and granules and to deliver them out from a discharge route 3. Thereby, the leakage of the powder and granules from the port 13 is prevented and the powder and granules are accurately metered.
