Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To secure a printed board at a specified position accurately by fitting a notched part made in one side of a printed board in a groove made at an engaging part on the housing side thereby determining the fixing position and then pushing a resilient piece provided on the opposite side of printed board into an engaging part on the housing side thereby securing the printed board to the housing. SOLUTION: A notched part 3 of a printed board 1 is inserted, in the direction B, into a groove made in the engaging part 6 of a housing 2 and the resilient piece 4 of printed board 1 is pushed fully into an engaging part 5. Consequently, the hooked stretching part of resilient piece 4 reaches the recess at the engaging part 5 and the printed board 1 touches a stud 7 and secured in place. Since the resilient piece 4 urges the printed board 1 in the direction B, the notched part 3 of the printed board 1 is pressed against the inner wall of the groove at the engaging part 6 thus determining the lateral position of the printed board 1. Consequently, the printed board 1 can be secured accurately at a specified position.

Title: Sheet feeding device and image forming device fitted therewith
Inventor: HAMAGUCHI KAZUYA
IPC: B65H1/18
Filed: 1994-09-13
Abstract: PURPOSE: To prevent overlapping feed of sheets, by measuring a thickness of a sheet to be fed, and by controlling the paper feeding speed in accordance with a thickness of a sheet. CONSTITUTION: A distance measuring sensor 37 measures a distance to the topmost one of sheets stacked on a stack tray 20 in a paper feeding device before a sheet is fed. Thus measured distance is subtracted from a distance to the topmost one of the sheets, measured after a sheet is fed so as to obtain a thickness of the sheet to bee fed. If the sheet has a thickness which is outside or a reference range in which a sheet can be processed at a normal paper feeding speed, such as a thine thickness, the sheet possible causes overlapping feed, paper jamming, inferior paper feed or the like at the normal paper feeding speed. Accordingly, the sheet is fed at a speed lower than the normal paper feeding speed. Thereby it is possible to prevent the sheets from being double fed.

Title: Separating and conveying device for thin sheet material
Inventor: KAWASAKI HARUHISA
IPC: B65H1/30
Filed: 1987-09-03
Abstract: PURPOSE:To make it possible to surely feed thin sheet materials one by one without the materials being damaged, by providing a reverse motor control section for controlling the output torque of a reverse motor coupled to a reverse roller in accordance with an output signal from a thickness sensor. CONSTITUTION:Friction forces by a conveyer roller 11 and a reverse roller 42 is applied to cards A. The cards A do not move if both friction forces are equal to each other. However, the roller is controlled so as to be rotated at a constant speed, the torque is therefore gradually increased exceeding the output torque of a reverse motor 41, causing the roller 42 to rotate clockwise so as to feed out the cards A. In this arrangement, the number of the cards A held between both rollers 11, 42 is detected by a gap sensor 6, and accordingly, the cards A are fed surely one by one independent from variations in influence due to a temperature atmosphere, a humidity and the like. When a plurality of the cards A is held between the rollers 11, 42, the torque instruction value to the motor 41 is set to be high while when a single card A is held therebetween, the torque instruction value to the motor 41 is set to be low, thereby it is possible to prevent a printed surface of a card from being damaged by an excessive load.

Title: Mechanism for preventing malfunction of gear
Inventor: UEDA MASASHI
IPC: G11B15/10
Filed: 1986-09-19
Abstract: PURPOSE:To prevent malfunction such as two cam gears being driven at the same time by blocking either of the gears from being driven by a rib even if the two cam gears tend to be driven simultaneously. CONSTITUTION:Circular-arc shaped ribs are provided respectively to two cam gears 1, 2, and the cam gears 1, 2 are arranged while being overlapped partly so that the circumferences drawn by the circular-arc shaped ribs are tangent to each other. In energizing solenoids 4, 5 simultaneously, the cam gears 1, 2 are driven to rotate clockwise at the same time and the ribs of the cam gears 1, 2 collide with each other. Suppose that the energizing force of an ejecting spring 9 is larger than that of an ejecting spring 8, the torque of the cam gear 2 is larger than that of the cam gear 1, the cam gear 2 is rotated so that the cam gear 1 is pushed back from the state where both the ribs abut against each other. Thus, the cam gear 1 is restored to its home position where its tooth missing part is opposed to an FW gear 3, the energizing of the solenoid 4 is released, and when the drive of the cam gear 2 is finished, the pin of the solenoid lever 6 is engaged with the step of the cam. Thus, the cam gear 1 is not rotated.

Abstract: PURPOSE:To increase the dispersibility of dyes and pigments into a binder without degrading the fixability to paper by previously pulverizing the binder to grain sizes of <=5 times the grain sizes of the dyes and mixing such binder with the dyes and pigments. CONSTITUTION:The binder 1 previously pulverized to the grain sizes of <=5 times the grain sizes as well as the dyes 2 and the pigments 3 are mixed and thereafter, the mixture is melted and mixed by a kneader. If the binder 1 is mixed with the pigments 3 and the dyes 2 after the binder is pulverized to the grain sizes of <=5 times the grain sizes of the dyes 2, the differences in the grain sizes are small and, therefore, the binder and the pigments and the dyes are easily mixed and the pigments 3 and the dyes 2 are disposed among the particles of the binder 1. Then, the mixture already dispersed with the pigments 3 and the dyes 2 among the particles of the binder 1 is kneaded at the time of melting and kneading the mixture dispersed with the pigments 3 and the dyes 2 among the particles of the binder 1 and, therefore, the dispersibility of the pigments 3 and the dyes 2 into the binder 1 is increased even if the degree of kneading by the kneader is lowered.

Title: Brushless dc motor driver
Inventor: YAMANOI MASARU
IPC: H02P6/06
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To reduce the size and cost of a brushless DC motor driver by detecting a current to a brushless DC motor, by using specific number of noncontact current sensors, and limiting the maximum current so as not to be excess current to the motor based on the detection signal. SOLUTION: A brushless DC motor driver comprises one noncontact current sensor 12 for detecting a current of a brushless DC motor to output a detection current signal d1. The signal d1 is compared with a reference signal (s) by a comparator 6, which generates a current limit signal (c). Thus, since the current flowing to the motor is detected by the one sensor 12, it is not necessary to use a current detecting resistor or two noncontact current sensors. Accordingly, reductions in size and cost of the driver can be realized.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To suppress a difference of turn performances in a turn direction to a minimum limit in the case of a stroke in a suspension mechanism and a roll of a car body. SOLUTION: In an axle suspension mechanism having a lateral rod 5 connecting a car body 2 and an axle 6, damping force of a hydraulic shock absorber 3a in a connection part 5b relating to the car body 2 of the lateral rod 5 is set larger than damping force of a hydraulic shock absorber 3 in a connection part 5a relating to the axle 6. When a vehicle is in low speed running, that is, when a piston in the hydraulic shock absorber 3, 3a is at a low displacement speed, a right/left different damping characteristic is given in a roll of the car body 2, abnormally floating up of the car body 2 is suppressed and a bad influence given to running performance is eliminated.  On the other hand, at high speed running time, since the piston in the hydraulic shock absorber 3, 3a is in a fast displacement speed, a difference is eliminated between the right/left damping characteristics, a bad influence is prevented from being given to the running performance.
