Title: One-way clutch
Inventor: KITAHATA KOJI
IPC: F16D41/07
Filed: 1992-11-12
Abstract: PURPOSE:To attain sufficient reduction of weight of a one-way clutch without breaking an inner holder. CONSTITUTION:An outer holder 3 and an inner holder 2 is made of plastic.

Title: Stock guide device in calender device
Inventor: ISENOBOU KUNIHIKO
IPC: B29C43/34
Filed: 1989-11-21
Abstract: PURPOSE:To make a quality of a product favorable by constituting the title device so that a gap is not formed between a radius of curvature part of a stock guide plate and a calender roll, by a method wherein at least either of the radius of curvature part facing on the calender roll or the inside facing on the central side in an axial direction of the calender roll out of a stock guide plate is formed of an elastic member. CONSTITUTION:In the case where a radius of curvature part 18b facing on calender rolls 3, 4 of a stock guide plate 18 is formed of an elastic member, the radius of curvature part 18b is expanded by feeding a fluid to a hollow part 18a and the radius of curvature part 18b is brought into contact with the outside circumferential surfaces of the calender rolls 3, 4. With this construction, plastic raw materials M fed to a bank do not leak out of the bank. Then in this case, even if the radius of curvature part 18b is worn, since the radius of curvature part 18b of the stock guide plate 18 is expanded and comes into contact with the calender rolls 3, 4 always, even in the case where the radius of curvature part 18b is worn, leaking of the plastic raw materials M outside of the bank can be prevented reliably.

Title: Output circuit
Inventor: MATSUZAWA MASAO
IPC: H03K19/0175
Filed: 1986-12-17
Abstract: PURPOSE:To obtain a large driving capacity, by providing a P-type MOS transistor whose gate is connected to the drain of an N-type MOS transistor, whose source to a second potential, and whose drain to an output terminal. CONSTITUTION:When an input signal 1 is set at a GND level, a P-MOS-TR3 is turned on, and the source voltage of the TR3 is set at a state where it is raided by the share of a threshold voltage VTP from the GND level, thereby, it goes to GND+VTP. The output of an inverter 10 goes to a power source voltage V, and a charge of potential difference GND+VTP-VDD is accumulated in a capacitor 2. Since the output of an inverter 11 goes to the GND level, an N-MOS-TR4 is turned off, and a P-MOS-TR6 is turned on. Therefore, the gate voltages of a P-MOS-TR5 goes to a VDD level, and the TR5 is turned off, and terminal 7 becomes high impedance. Also, when the signal 1 goes to the voltage VDD, the terminal 7 goes to the VDD level.

The image is temporarily stored in an image memory 2. The straight line of each side of the rectangular parallelopiped frame is extracted by a straight-line extracting and processing part 5 from the image read out of the memory 2. A position/attitude measuring part 6 measures the three- dimensional position and the attitude of the rectangular parallelopiped frame based on the straight lines and converts the data into the three-dimensional position and the attitude of the vehicle. Thus, the three-dimensional position and the attitude of the running vehicle can be accurately measured. The composited image is made to run based on the data, and the composited image having a high presence feeling can be formed.

IPC: G06F13/36
Filed: 1986-12-19
Abstract: PURPOSE:To reduce the amount of hardware in a peripheral circuit by using a memory whose data bus width is narrower than that of a microprocessor. CONSTITUTION:In case of reading a ROM 3 whose data bus width is narrower than that of a microprocessor 1, a pattern sending means 4 outputs a one-byte pattern, which does not exist in an instruction code, to the upper side of a data bus 9, and simultaneously, a one-byte instruction is sent to the lower side from the ROM 3. When a pattern from the means 4 is detected, a recognizing means 6 stores the instruction of the ROM 3 in a storage means 8 and causes a bus cycle executing means 7 to continuously execute the next bus cycle. Thus, the number of bus cycles which is determined by data bus widths of the processor 1 and the ROM 3 are executed and instructions sent from the ROM 3 are stored as one instruction in the means 8, and the amount of hardware of the peripheral circuit is reduced.
