Title: Liquid suction/discharge device
Inventor: TSUJIMOTO HARUO
IPC: F04F1/00
Filed: 1983-03-18
Abstract: PURPOSE:To prevent entaglement or choking of pump even when used for suction/discharge of mud by constructing such that liquid is fed from supply source not through a pump but through a storage tank to the liquid deivery port through operation of four-way valve. CONSTITUTION:When sucking liquid from supply source, it is sucked through a suction port 1a into a liquid storage tank 1 by means of a vacuum pump 2 and a four-way valve 9. While when discharging liquid, a gate valve 7a at the liquid suction port 1a is closed while a gate valve 7b at the liquid delivery port 1b is opened to lead the open end of liquid discharge port (not shown) coupled with said port 1b to predetermined discharge place, then the pump discharge port 2b and liquid storage tank 1 are communicated through operation of four- way valve 6 and the vacuum pump 2 is driven under the state where the pump suction port 2a is communicated to the atmosphere thus to deliver liquid in the storage tank 1 through liquid delivery port 1b. With such arrangement, entaglement of solid material or choking of pump can be prevented even when used for suction/discharge of mud.

Title: Forced combustion device
Inventor: ITO SHUJI
IPC: F23L1/00
Filed: 1988-02-29
Abstract: PURPOSE:To increase the quantity of air taken-in through an intake duct, by providing auxiliary intake ports small in aperture area in the vicinity of the downstream end of the intake duct. CONSTITUTION:A forced combustion device comprises an intake duct 2 bent into an L shape in the vicinity of a part thered of for connection to a fan 1, and the bent part is provided with small holes 6, 6, to be auxiliary intake ports, at positions opposed to a suction port 10 of the fan 1. Combustion air is taken in through an intake port and through the auxiliary intake ports 6. Since the distance from the auxiliary intake ports to the suction port 10 of the fan 1 is short and a pressure loss generated while air taken in through the auxiliary intake ports reaches the suction port 10 of the fan 1 is small, air in substantially the same quantity as that in a conventional device is taken in through the intake port. A predetermined quantity of air is taken in also through the auxiliary intake ports, so that the quantity of air is increased by the quantity taken in through the auxiliary intake ports. Thus, deficiency in the quantity of air fed into a combustion chamber at the time of forced combustion can be obviated.

Abstract: PROBLEM TO BE SOLVED: To perform contour emphasis for suppressing overshooting and preventing the degradation of image quality. SOLUTION: In a secondary differential signal generation part 1, secondary differential signals s5 for time sequentially inputted successive three pixels are generated. Then, an overshooting suppression part 2 discriminates whether or not it is the case that the position of the pixel under consideration exceeds a threshold lim, and in the case of discriminating that it exceeds the threshold lim as the discriminated result, outputs zero to an adder 20 as the secondary differential signal for the two pixels in front and at the back with the pixel under consideration at the center, that is for the total of five pixels. The adder 20 adds the signals of the pixel under consideration and the signals from the overshooting suppression part 2 and outputs them as contour emphasis signals.

Title: Exciting current controller of generator for vehicle
Inventor: MARUYAMA TOSHINORI
IPC: H02J7/16
Filed: 1993-03-09
Abstract: PURPOSE:To provide an exciting current controller of a generator for a vehicle which has a simple circuit configuration and needs no large capacitor but which can contol the stoppage of generation after an engine starts. CONSTITUTION:A switching means 11 allows exciting current of a generator 2 to flow intermittently. A counter (a generation start delaying means) 18 sends a generation stopping signal to the switching means 11 for a specified period of time after an engine starts up, making the generation voltage at a specified level, for example, the voltage at which a battery can be charged, or lower for a specified period of time after the engine starts up. A gradual exciting circuit (means for gradually increasing exciting current) 15 gradually increases a duty ratio of the switching means 11 by sending a duty control signal which changes gradually to the switching means 11 after a generation stoppage period is over. Since a counter 18 counts the number that the duty control signal changes from a first set value to a second set value, a capacitor or a large-scale counter is not necessary.

Filed: 1985-03-11
Abstract: PURPOSE:To attain clamp processing with high accuracy without any malfunction by combining a delay type clamp pulse generating system with excellent phase tracking and a PLL type clamp pulse generating system with excellent noise suppressing performance to obtain a clamp pulse. CONSTITUTION:A delay circuit 3 generating the 1st clamp pulse C corresponding to a pedestal part in response to a synchronizing signal of an input video signal and a PLL circuit 7 generating the 2nd clamp pulse B corresponding to the pedestal portion synchronously with a synchronizing signal are provided and the 1st and 2nd clamp pulses C, B are given to an AND gate 8, and its output is used as a clamp pulse. Since a pulse noise is included in the 1st clamp pulse but the pulse noise is limited in the 2nd clamp pulse, no noise appear in the AND output. When the phase of the synchronizing signal is fluctuated, the 2nd pulse does not follow up it immediately, but the 1st clamp pulse traces it and while there is a phase difference between the both, no AND output exists and no clamp operation is attained in a portion other than the pedestal.

Abstract: PURPOSE: To make possible equal-speed scanning with a simple constitution by aligning the center of the radiation luminous flux or read luminous flux to the plane inclusive the rotating axis of a rotary polyhedral body.  
     CONSTITUTION: Rays out from a light source 1 are made to a converging luminous flux through a lens 12 and lens 13 and enter a rotary polyhedral mirror 15. The center of said luninous flux is aligned approximately to the plane inclusive the rotating axis of the rotary polyhedral body. The luminous flux reflected by the rotary polyhedral body 15 focuses at the point 18 on a scanning surface 17. As the rotary polyhedral body 15 is rotated at an equal speed, the condensing point 18 moves nearly at an equal speed on the scanning surface 7, by which approximately equal speed scanning is realized. It is also possible to realize two-dimensional scanning by placing a recording medium or original on the scanning surface 17 and moving the same parallel in the direction of an arrow 19.
