Patent JP-H0342224-A (JP)
Title: Method for extrusion molding of polyimide and polyimide pellet used therein
Inventor: SARUWATARI MASUMI
IPC: C08L79/08
Filed: 1990-03-27
Abstract: PURPOSE:To stably mold a product reduced in thickness fluctuation and excellent in mechanical strength and electric insulating properties by melting polyimide having a specific repeating structural unit under heating to process the same into a pellet form and heat-treating the pellets to set a degree of crystallization to specific % or more before supplying the same to an extrusion molding machine to perform molding. CONSTITUTION:Polyimide having a repeating structural unit represented by formula [I] (wherein x is a single bond or a hexafluoroisopropylidene group) is heat-treated to form polyimide pellets usually having a degree of crystallization of 5% or more. In this case, the heat treatment temp. is pref. 250 - 370 deg.C. When said temp. is below 250 deg.C, crystallization is very slow and, even when the temp. exceeds 370 deg.C, crystallization is slow and said temp. is not pref. because the resin begins to melt. When the degree of crystallization is below 5%, it is not pref. because the extrusion amount at the time of extrusion varies and extrusion becomes impossible according to circumstances and foaming or die refuse is generated. The upper limit of a degree of crystallization is not especially prescribed but a pref. range of a degree of crystallization is 5 - 50%. Further, stirring is pref. performed during heat treatment in order to prevent the partial fusion of the resin.

Title: Retry control device for electronic computer
Inventor: IKEDA KOUICHI
IPC: G06F11/14
Filed: 1980-06-06
Abstract: PURPOSE:To reduce the amount of hardware required for discriminating whether retry is permitted or not, by providing one counter for the whole of a CPU. CONSTITUTION:When a fault is detected somewhere, ''1'' is given to an OR signal 11 of the fault detection signal from each part of a CPU, and the output of respective timing pulses is suppressed in gates 120-12N-1. A counter 13 generates N different values successively for respective inputs of N phase timing pulses and is returned to the original value after clapse of one machine cycle. Consequently, the value of this counter 13 is read to detect the progress of the output of N phase timing pulses.

Title: Malfunction detector for pwm control motor
Inventor: NAKAJIMA HIROSHI
IPC: H02P7/29
Filed: 1988-03-29
Abstract: PURPOSE:To detect the malfunction of a motor irrespective of the amplitude of a current by discriminating the malfunction according to the value of a DC imaginary resistance obtained on the basis of the duty ratio of a current, an applied voltage and a PWM signal to a DC motor.

Title: Preparation of keyboard with pattern such as character or mark
Inventor: SUMI TAKAO
IPC: H01H11/00
Filed: 1983-04-27
Abstract: PURPOSE:To attain to enhance efficiency and to prevent the erroneous attachment of key caps by dispensing with the discrimination of the indivisual patterns of the key caps, by forming patterns on the key caps in such a state that the key caps having no pattern preformed thereto are attached to the keyboard. CONSTITUTION:Key caps 1 are set to a keyboard 2 and a far infrared ray reflective plate 3 is placed so as to cover the parts other than the key caps 1. In the next step, only the key caps are heated and a transfer sheet 4 is placed on the key caps 1 so as to contact the pattern layer 5 with the surfaces to be transferred of the caps 1. Subsequently, when the transfer sheet 4 is pressed from the substrate sheet side 7 thereof by using a transfer pad 8 and the surfaces to be transferred of the caps 1 are brought into close contact with the pattern layer 5, the thermally transferrable dye in the pattern layer 5 is activated by the heat of the caps 1 and, when this contact state is held for a definite time, the dye is transferred into the key caps to form a pattern such as a character or a mark to the surface of each cap. As mentioned above, because it is unnecessary to discriminate the surface pattern of each key cap, no erroneous attachment is generated.

Title: Method for coating mo powder with cu
Inventor: FUJII TAKAHIRO
IPC: C25D5/28
Filed: 1992-02-27
Abstract: PURPOSE:To form a uniform Cu coating layer on the individual particle surfaces of Mo powder. CONSTITUTION:The Mo powder is charged into an electroplating bath adjusted to alkalinity of >=11 pH and while the Mo powder is maintained in a fluid state, the Cu coating layer is formed by electroplating. The pH of the electroplating bath is adjusted by the amts. of alkaline materials, such as KOH and NaOH, to be added. The MoO3 based oxide film existing on the surface of the Mo particles elutes into the plating bath in an aq. alkaline soln. of >=11 pH and the particle surfaces are maintained at the metal surfaces of high activity. The Cu plating layer is, therefore, deposited uniformly on the individual Mo particle surfaces. The control of, for example, the coefft. of thermal expansion, thermal conductivity, electrical conductivity, etc., of sintered products is enabled by changing the adhesion of the Cu coating layer according to target compsns.

Title: Servo controller for shutter speed
Inventor: KUROSU TOMIO
IPC: G03B7/087
Filed: 1987-03-30
Abstract: PURPOSE:To permit arbitrary combination of an aperture diameter and exposing time at the time of exposure control by setting the value of a speed command signal at substantially 0 at an arbitrary timing during opening action, thereby stopping a shutter vane in common use as an aperture vane at an arbitrary position. CONSTITUTION:The shutter vane 13 acts to open when the rotating speed of a servo motor M is set at a positive speed. The vane acts to maintain an F value when the rotating speed of the motor M is set at 0 and the vane 13 acts to close when the rotating speed of the motor M is set at a negative speed. The value of the speed command signal is set at substantially 0 at the optional timing during the opening action, by which the vane 13 in common use as the aperture vane is stopped at a specified aperture diameter. The speed command signal is gently varied at the time when the vane 13 shifts from the opening action to a stop action. The exposure control at an arbitrary combination of the aperture diameter and exposing time is thereby permitted.
