Title: Power supplying method for printer
Inventor: YAMASHITA JUN
IPC: B41J2/44
Filed: 1987-07-10
Abstract: PURPOSE:To contrive a stable and accurate printing operation, by supplying an AC power synchronized with the period of a line data printing operation of a printer, and setting a cutoff point of a power supply at the time of switching to be coincident with or proximate to the zero point of the AC power. CONSTITUTION:When a LED-driving voltage DV is oscillated and outputted from an oscillator 21, a gate control signal GC outputted from a voltage comparator 31 becomes a signal containing logical levels of '1' and '0'. In a driver gate array 13, driver gates corresponding to the logical level '1' are opened synchronously to the signal, and the signal level at an output terminal thereof is brought to the logical level of '1'. By this, only the LEDs in a LED array 14 which correspond to data of logical level '1' in line data are operated to emit light. In a LED printer, a latent image is formed on a photosensitive body on the basis of the emission of light from the LED array 14, resulting in a print image. Based on the opening and closing operations of the driver gate array 13, the switching of the LED array 14 is constantly carried out at a zero level point of the voltage DV, so that noise or a surge voltage is hardly generated during a printing operation.

Title: Picture memory device
Inventor: EMORI TAKEO
IPC: H04N5/907
Filed: 1983-09-20
Abstract: PURPOSE:To decrease the number of a memory board to be used by switching timewise a vertical address to a horizontal address so as to improve the utilizing factor of a memory capacity in the picture memory device of a PAL system picture signal. CONSTITUTION:The memory board 4 is constituted by adding four 3-bit changeover devices 20-23 and using a 36-phase clock. The 8th address V8 is used as a changeover control pulse out of 10-bits outputted from a read/write vertical address generator 11. When the address V8 changes from an L to an H, horizontal addresses H2-H4 are replaced on the location of 3-bit vertical addresses V5-V7, while a high level is inputted to the horizontal addresses H2-H4. The increase in the vertical addresses is suppressed by inserting the vertical addresses of a prescribed bit or over to an excess part of the horizontal address within a prescribed bit in this way.

Title: Reflection type encoder
Inventor: TAKAHASHI KAZUHISA
IPC: G01D5/347
Filed: 1983-09-19
Abstract: PURPOSE:To obtain a compact and thin encoder, whose assembling accuracy is tolerant, by a consititution, wherein a light emitting element and a light receiving element are provided on one side of a slit plate side by side, and the first and second reflecting mirrors are fixed on the other side of the slit plate. CONSTITUTION:A moving slit plate 13, which has slits 12 provided as a specified interval, is an annular body that is attached to a rotary shaft. The plate 13 is moved in the direction X shown by an arrow, with the rotation of the rotary shaft. Light from a light emitting element 2 is reflected by a reflecting surface 16a of a first reflecting mirror and a second reflecting mirror 17 by way of a slit 12a, and received by a light receiving element 3 by way of a slit 12b. When the light has passed the slit 12a in the oblique direction, the light is dispersed by notched parts 19 and does not reach the second reflecting mirror 17. Therefore, accurate reading can be performed without fixed slits for obtaining a shutter effect. Since the light emitting element 2 and the light receiving element 3 are provided on one side of the slit plate 13, the device can be made thin.

IPC: F02M59/10
Filed: 1991-07-15
Abstract: PURPOSE:To miniaturize a pump and improve its reliability. CONSTITUTION:Rollers 27, 50 are rotatably fitted on the cam face 24 of a cam shaft 23, and the roller on the side of the cam shaft 23 is brought in contact with a tappet 39 provided on the plunger side.

Since no roller is equipped on the side of the tappet 39, the weight of a reciprocating system can be decreased, and reciprocating inertia of the reciprocating system can be decreased. Since energizing force of springs can be decreased, the body of a pump can be downsized.

Title: Radar equipment
Inventor: SHINONAGA MITSUYOSHI
IPC: G01S13/52
Filed: 1985-08-07
Abstract: PURPOSE:To make it possible to effectively estimate the Doppler frequency of a desired object even from a receiving signal of any mode, by directly extracting a Doppler frequency component from a signal received and demodulated without changing local signal frequency. CONSTITUTION:The phase component code of either one of the reflected signal from a target of the radar transmission pulse temporarily stored in a memory means and the reflected signal received at time different from the stored signal is reversed by a phase code reversal circuit 72 and said two signals are multiplied by a multiplier 73. The multiplied signal is timewise averaged by an averaging circuit 74 and only a phase component is taken out from the signal content by a phase operation circuit 75 to calculate a phase value. This phase value is calculated in a form containing Doppler frequency. Hereupon, by multiplying phase value by the function of a transmission pulse interval being a preset known value through a multiplier 76, only Doppler frequency can be purely extracted and estimated.

Abstract: PURPOSE:To shorten a reliability acceleration test time by providing a word line simultaneous selection means, making the output ends of the signals of the same level and the inverse level as each bit of the address signal of an address buffer an active level also and making plural word lines a selection level simultaneously. CONSTITUTION:When a test signal TSTb becomes the active level, the levels in the output ends of the signals A1, A1b, A2, A2b... of the address buffer 1 become 'H' also. Thus, the output ends, as well of the inverters IV9-IV12... of an X decoder 3 become 'H' also, and transistors Q3-Q6 are turned on, and the word line drive voltage VWd of higher level than at a regular operation time is applied to each word line. In such a manner, since plural pieces of word lines become the higher level than at the regular operation time simultaneously, the reliability acceleration test time is shortened.

Title: Reversing speed controlling device for vehicle
Inventor: FUJITA HARUYASU
IPC: B60W10/18
Filed: 1985-08-09
Abstract: PURPOSE:To prevent a vehicle speed from being fluctuated when a brake is excessively applied by configurating a device in such a way that an inlet port of a cylinder device, which is rendered effective to brake a vehicle upon exceeding of a flow rate from a pump which discharges the flow rate proportional to a reversing speed, is communicated with a discharge port of the pump by way of a stop valve. CONSTITUTION:When a vehicle is reversing, hydraulic oil which is introduced into a cylinder chamber 11a from an inlet port 18 with a flow rate proportional to a vehicle speed, flows into a cylinder chamber 11b through an orifice 22, and then returns to a reservoir tank through an outlet port 19. In this case, the flow rate discharged from a pump is increased as the vehicle speed increases, and when it exceeds one limited by the orifice 22, a piston 12 moves upward allowing a master cylinder (not shown) to be actuated by way of a rod 12a so as to brake the vehicle. In this configuration, the inlet port 18 is connected with a discharge port of the pump by way of a stop valve 17, and the stop valve 17 is rendered effective upon increasing of pressure in the cylinder chamber 11a because the piston 12 is restrained from moving, so as to shut off the flow discharged from the pump.
