Title: Ink jet element driving circuit of ink jet printer
Inventor: NAKAJIMA TORU
IPC: B41J2/055
Filed: 1990-03-23
Abstract: PURPOSE:To make an ink jet element jet good printing quality ink by a method wherein a time function is established to a varying voltage with time generating part so that a time elapsing waveform of a voltage value becomes a waveform by which a meniscus before jetting ink comes to have a required mode. CONSTITUTION:A functional form of a time function and a memory mode in a RAM 30 are so established that a meniscus before jetting ink at an ink jet opening of an element 3 becomes a required mode in which a meniscus before jetting ink at an ink jet opening of the element 3 becomes a required mode without generating each cause of non straight advancing phenomena or the like of jet ink bringing deterioration of printing quality by impressing a voltage value V varying with time until a signal 2c reaches an L level on and after time when the signal 2c has varied from the L level to a H level. Consequently, an output circuit O to which a binary signal 6 of a H level is inputted, while the signal 2c is kept at H level, outputs drive voltage 7a, for instance, presenting a time elapsing waveform 33.

Title: Main storage write control device
Inventor: TOYOSHIMA ATSUSHI
IPC: G06F12/16
Filed: 1983-04-27
Abstract: PURPOSE:To always write correct information in a main storage device by changing to a partial write again when an erroneous data is detected in a part which is not changed by the partial write among a read-out data from a buffer memory. CONSTITUTION:When a code error is detected by an error detector 11 and an error detecting signal 15 is outputted, with regard to a byte by which logic ''0'' is set to a partial write byte designating register 5, the contents of a data register 8 set by an address of the contents of a buffer address register 13, an output of a partial byte convertor 10 is changed again as per the contents of the partial write byte designating register 5. A main storage device 1 executes a partial write operation for writing the contents of a corresponding byte of a merge register 4, to only a byte by which an output of the partial write byte convertor 10 of an address position designated by the contents of an address register 6 is logic ''1''.

Title: Tape tension adding unit
Inventor: TAKAMIYA TAKEHISA
IPC: B65H23/06
Filed: 1978-06-19
Abstract: PURPOSE: To enable to control the tape tension almost at a constant value, by changing the spring force activating the arm with the operation of the operating member.  
     CONSTITUTION: When the radius of tape winding is increased, the force Q exerted on the arm 2 with the tape tension t is reduced, and thus, even if the radius of tape winding is changed, the tape tension t is almost constant. When the operating member 11 is moved to the direction of arrow, the spring 9 is stretched via the lever 7 to increase the activating force. Also, in this case, the tension t can be maintained constant substantially independently of the change in the tape winding radius. Thus, the change in the valve of spring activating the arm allows the tape tension to desired value almost constant with a simple constitution.

Abstract: PURPOSE:To maintain a proper air-fuel ratio, improve operating characteristics and reduce noxious components in an exhaust gas, by arranging such that an auxiliary throttle valve may close while in cooling an engine, in such an engine having two inlet passages and adapted to inject fuel only to a main port. CONSTITUTION:In an engine having main and auxiliary inlet passages and adapted to inject a fuel only to a main port, an auxiliary throttle valve 14 is provided in the standby inlet passage 5 in such a manner that the auxiliary throttle valve 14 may be closed via an actuator by means of a control circuit 26 which outputs to a negative pressure switching valve 22 a control signal upon a cooling water temperature to be detected when it is lower than a preset level, and thereby allowing a total flow rate of supply air to pass through the main inlet passage. In this manner, it is made possible to prevent a lean air-fuel ratio in an initial stage of acceleration and a rich air-fuel ratio immediately after deceleration, while simultaneously reducing HC discharge with no need of increasing a fuel rate in an initial stage of acceleration.

IPC: B01D33/04
Filed: 1991-03-13
Abstract: PURPOSE:To surely stabilize the traveling without damaging filter cloth in a filter cloth traveling sludge dehydrator even if dehydrating filter cloth of relatively low tensile strength is used.

Title: Image forming device
Inventor: KASHIWABARA ATSUSHI
IPC: H04N1/21
Filed: 1989-03-29
Abstract: PURPOSE:To reduce a burden on a controller side and to reduce a cost by a method wherein pixel data is read from a memory means other than an object to be written by a writing means in synchronism with a reference clock generated in a clock signal generation means. CONSTITUTION:A multivalent image signal (data 1,...) is inputted to a demultiplexer 3 to be alternately written into a memory 1 and a memory 2 at every cycle of a controller clock signal CCLK. For example, odd-numbered data 1, 3, 5,... are written into the memory 1, and even-numbered data 2, 4, 6,... are written into the memory 2 under control. This writing operation is based on the controller clock signal CCLK. On the other hand, in synchronism with an image clock signal VCLK data is read from one of the memories 1, 2 which is free from the writing operation. The read data is inputted to a data selector 4 to become a signal VD. The signal VD is inputted to a pulse width modulation circuit 5 to become a laser drive signal LD in accordance with a density.
