Title: Pump
Inventor: NISHIKAWA KUNIO
IPC: F04D9/02
Filed: 1987-06-25
Abstract: PURPOSE:To reduce the manufacturing cost of a pump by forming an impeller of a flat core metal and synthetic resin coating to cover its surface, and an impeller blade protrusively formed in front of the core metal and in a body with the coating. CONSTITUTION:A coating 19 composed of polyurethane rubber is formed on a core metal 18 so as to cover a surface except a hexagonal head part 18c and a cylindrical part 18a. The coating 19 is protrusively and unitedly formed with a pair of impeller blades 20 in front of the core metal 18. Thus the coating 19 can be easily ground to balance an impeller in its rotation, and the core metal 18 can be therefore formed of inexpensive cast iron. In addition to that, the impeller can dispense with the conventional annealing and quenching processes.

IPC: G03G9/09
Filed: 1986-07-08
Abstract: PURPOSE:To widen a fixing temp. range without abnormally increasing the lower limit temp. for fixing of a toner by using a binder resin formulated with a specific resin. CONSTITUTION:The developer toner consisting of a coloring material and binder resin contains the toner formed by using a polyester resin which is synthesized by a bisphenol type diol and polyvalent carboxylic acid and has 50-150 deg.C softening point and copolymer resin of a styrene polymer or styrene monomer having >=3.5wt. average mol.wt. (Mw)/number average mol.wt. (Mn) and >=100,000 Mw and acrylic acid deriv. The structure and mol.wt. of the resin are changed when force is exerted to the resin component if Mw/Mn is <3.5 in the stage of kneading the toner. For example, a hot offset generating temp. is low when Mw/Mn is thereby made <3.5. The Mw is required to be made >=100,000 in order to suppress gloss, to make the lower limit temp. for fixing slightly high and the hot offset generating temp. slightly high and to widen the fixing temp. range.

Title: Clock phase control circuit
Inventor: KOBAYASHI NAOKI
IPC: G06F1/10
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To automatically generate a hold circuit for holding the value of a counter inside a clock phase control circuit. SOLUTION: A phase comparator circuit 11 compares the phase of an output clock COUT with that of a reference clock REF and based on a count-up instruct signal (u) and a count-down instruct signal (d) outputted from the phase comparator circuit 11, an optimum counter value detection circuit 12 outputs a hold signal HOLD. When the phases of the output clock COUT and reference clock REF get closer, a counter 13 holds its value based on the count-up instruct signal (u), count-down instruct signal (d) outputted from the phase comparator circuit 11 and the hold signal HOLD outputted from the optimum counter value detection circuit 12. Corresponding to the value of the counter 13, a delay circuit 14 increases/decreases the delay quantity of an input clock CIN and controls the phase of the output clock COUT back and forth.

Title: Square beam direction detection system
Inventor: YASUTAKE NOBUYUKI
IPC: H01L21/027
Filed: 1978-12-20
Abstract: PURPOSE: To detect the direction of a square beam with a high precision by a simple constitution by scanning the square beam with a pair of beam detection means arranged orthogonally to the scanning direction and detecting the time slippage of output signals from detection means.  
     CONSTITUTION: A pair of beam detection elements 3 and 4 utilizing the depletion layer in semiconductor PN-junction are arranged orthogonally to the beam running direction shown by the arrow. When square beam 2 is inclined and scanned, current I 1  is flowed to detection element 3 first, and next, current I 2  is flowed to detection element 4 after a little delay. Respective currents are converted to current waveforms a and b through amplifiers 5 and 6 and are further converted to voltages and are compared with a prescribed threshold voltage by comparators 7 and 8 and become output waveforms c and d. These output waveforms are caused to pass through exclusive OR circuit 9 to obtain output e. The magnitude of width W on the time t base of the H level of this output indicates the magnitude of inclination between direction A of a pair of detection elements 3 and 4 and side direction B of square electron beam 2. Thus, the direction of the square beam can be detected with a high precision.

Title: Method of forming longitudinally attached tape into cylindrical shape
Inventor: HARANO FUMIO
IPC: H01B13/26
Filed: 1980-11-12
Abstract: PURPOSE: To exclude defective forming by a method wherein a tape is longitudinally attached along a linear body such as a cable core or the like and formed around it into a cylindrical shape, by providing a receiving plate for supporting the weight of the linear body, the height of the receiving plate can be adjusted.  
     CONSTITUTION: In forming the longitudinally attached tape 2 into a cylindrical shape, a height adjusting apparatus 6 is employed under the tape 2 such that the receiving plate 5 is engaged with the tape from just before the point of the tape where the linear body 1 contacts the tape surface due to the catenary of the linear body 1 to just before the entrance of a forming die 4 through which the linear body 1 is introduced into the die. Thus since the weight of the linear body is supported by the receiving plate and would not be directly supported by the forming die, defects such as longitudinal wrinkles or the like to the tape would not occur, and since the catenary of the linear body lies on the receiving plate, the adjusting operation of the height of the linear body is not required.

Filed: 1989-06-23
Abstract: PURPOSE:To efficiently avoid malfunction caused by a defect relating to advanced control by making the advanced control ineffective when a coincident condition is detected in an instruction address conveyer mechanism and afterwards, immediately restarting the execution of an instruction train continuously. CONSTITUTION:By a first means 104, the specified instruction address in the instruction, to which the malfunction is generated, is set as a comparing address. When the specified instruction is executed and the instruction address coincident condition is detected by a second means 105, the execution of the instruction train is interrupted by a third means 107. Next, after the advanced control is made ineffective by the third means 107, the advanced control is initialized and the execution of the instruction train is continuously restarted. Thus, the malfunction with possibility to be generated can be avoided by initializing the advanced control. Since the advanced control is made ineffective and initialized only once and the function of the advanced control itself is not reduced, it is possible to ignore performance is lowered.
