Filed: 1990-04-05
Abstract: PURPOSE:To apply lubricant without unevenness in a short time by applying the lubricant on the inner surface of a die from nozzles arranged at the upper side of a lower punch while ascending the die for press-compacting Ti powder or mixed powder containing Ti. CONSTITUTION:At the time of ejecting a green compact 22 from the die, the die 12 is positioned at the lowest point of vertical movement. Successively, when the die 12 starts ascending after the removal of the green compact 22, a solenoid valve 33 opens and the lubricant held in a tank 31 of lubricant supplying device 30 starts flowing out under pressure and flow out by a pump 32 from four nozzles 16 arranged at a groove 15 in the lower punch 11. The flowing-out lubricant is applied over the whole circumference of side wall of the die. When the die 12 comes to the most upper point and the valve 33 is closed, the flow-out of lubricator is stopped. Successively, the raw material powder material 14 is charged to space 21 formed with the die 12 and upper face of the punch 11, and by descending the upper punch 13, the powder material 14 becomes the green compact.

IPC: H03K5/1534
Filed: 1980-07-04
Abstract: PURPOSE:To pick up the front edge pulse only, by erasing back edge pulse through the feedback of the front edge pulse through delay. CONSTITUTION:A pulse input signal A in pulse width T0 applied to an input terminal 2 is applied to one input terminal of a subtraction circuit 4 and applied to another input terminal of the circuit 4 via a delay circuit 6 in the delay time T, allowing to output pulses from the circuit 4.

IPC: G01B9/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To make optical adjustment simple and very small, and reduce influence on wavelength fluctuation of a laser light source to a minimum. SOLUTION: Coherent lights outputted from a light source part 1 pass a coupling part 2, and the planes of polarization are reserved. The lights enter a light emitting system 3, which applies inverse code phase modulation with almost the same amplitude to the respective luminous fluxes and outputs at least two irradiation luminous fluxes. In an irradiation optical system 4, the luminous fluxes are condensed, deflected and cast on measurement points of a scale part 5. It diffracts at least two irradiation luminous fluxes in almost the same direction, and diffraction luminous fluxes enter a light receiving system 6, which receives the diffraction luminous fluxes and introduces them to a light receiving part 7. It receives the fluxes and converts them to electric receiving signals.  On the basis of the receiving signals from the light receiving ' part 7, a displacement measuring part 8 analyzes components and obtains displacement of the scale part 5.

IPC: G01R31/26
Filed: 1979-07-19
Abstract: PURPOSE: To make it possible to reduce the quantity of diagnosis data by converting only varied parts of the preceding test and expected output pattern into data, and restoring to the original and resetting the expected output pattern by an expected output pattern setting part.  
     CONSTITUTION: When a diagnosing input pattern is imparted from a memory device 1 to a part 2 to be diagnosed, the output pattern of the part to be diagnosed appears at one input side of a comparison part 3. On the other hand, with respect to the first test, the expected output pattern is directly set at each of memory elements corresponding to each of output terminals within the expected output pattern setting part 4 from the memory deviced 1 with respect to the full output terminal, and is compared 3 with the output from the part 2 to be diagnosed. With respect to the second test and downward, the expected output pattern of the preceding test is housed in the memory element of the expected output pattern setting part 4. Since the expected output pattern obtained from the memory device 1 is an information showing a position different from the preceding test, only the content of the designated memory element in the expected output pattern setting part 4 is reset by the data obtained.

Primary heat treatment is applied to the exposed glass to generate metal colloid of Ag and secondary heat treatment is further applied thereto to allow said glass to be easily resolvable around the metal colloid nuclei and Li2O-SiO2 is crystallized. Next, when half-etching is applied to both surfaces of the glass by an aqueous fluoric acid solution, parts 23, 24 are etched at a faster speed to form ring shaped protruded parts 25, 26. Subsequently, the entire single surface of the photosensitive glass 21 is masked by paraffin 28 and etching is performed until a hole is pierced from the protruded part 26 to the protruded part 25 in the opposite side.

IPC: H04L13/08
Filed: 1989-04-11
Abstract: PURPOSE:To reduce the storage capacity of a buffer to be installed by applying the transmission of the order and the read of a reply data in the same prescribed period. CONSTITUTION:An order control circuit 2 sends an order (c) to an execution circuit 5 for a prescribed period t0 with a transmission signal (a) from a central processing circuit 1. The execution circuit 4 receiving the order (c) writes the data of the result of executing the order into a reply data buffer 5. In this case, let the time from the order transmission till the end of reply data write be t1, then a reply control circuit 3 reads a reply data for the prescribed period t0 with the delay of a time t2 form the initial order transmission. Thus, the reply data buffer 5 has only to provide a storage capacity capable of storing the reply data (e) by the time of at least (t1+t2).
