Patent JP-S63286878-A (JP)
Title: Image forming device
Inventor: SAITO MASANOBU
IPC: G03G15/16
Filed: 1987-05-19
Abstract: PURPOSE:To effectively prevent lowering in transferring rate caused by contamination, by applying a bias voltage of polarity opposite to that of toner a transfer member at the time of transfer and another bias voltage of polarity equal to that of the toner at the time of non-transfer. CONSTITUTION:By applying a bias voltage Va of polarity opposite (plus in this case) to the toner to a transfer charger 6 during the period of tA-tB after a photosensitive body 1 is driven, the surface potential of a transfer roller 2 is maintained at Vc and the toner image on the surface of the photosensitive body 1 is transferred to a transfer material. Then, during the period of tB-tC after the transfer material passes the transferring section, another bias voltage Vb of polarity equal to that of the toner is applied to the charger 6 and the surface of the transfer roller 2 is electrostatically charged with surface potential Vd. As a result, not only the transfer of the toner existing on the surface of the photosensitive body to the transfer roller 2, but also that traction of the floating toner to the roller 2 can be prevented effectively. Therefore, the contamination of the succeeding transfer materials and the lowering in image quality can be avoided.

Title: High grade treatment of organic waste water
Inventor: HORIUCHI ASAO
IPC: C02F1/52
Filed: 1978-09-29
Abstract: PURPOSE: To provide an effective and compact waste water treatement with an reduced amount of chemical consumption, in the system wherein organic waste water is added with a coagulant of ferric salt to allow suspended materials to be flocked for separation, then treated with active carbon for adsorption.  
     CONSTITUTION: Organic waste water such as sewage oozing out from reclaimed land using waste is added with coagulant of ferric salt such as ferric sulfate and ferric chloride in an amount of 10W1000ppm, converted as iron atom and made to pH 3W5.5. The process allows suspended matter, organic materials, and coloring components to be coagulated as flocks of ferric hydroxide. Thereafter, the treated waste water is neutralized with alkali such as slaked lime and separated by processing with auxiliary coagulant and pressurized floating. Then, the treated water is filtered and adsorbed by active carbon. The process thus provides a high-degree treatment of organic materials in the waste water while minimizing chemical consumption.

Title: Forward/reverse rotation detector for rotating shaft
Inventor: ANAMI YOSHINORI
IPC: G01P13/04
Filed: 1982-07-08
Abstract: PURPOSE:To enable the detection of the forward and reverse rotation of a rotating shaft at a high accuracy by providing a groove and a pick up of a detector section with a computation driving circuit for computing outputs thereof. CONSTITUTION:When a rotating shaft rotates forward, the H level at the output terminal Q of an FF38 is so short in the range that the H level state occurs four times only when at 12 deg. per one turn thereof. As a result, a counter 42 counts by 2 and when reset with the selection of a switch 44, keeping a setting signal from being inputted into an FF46, the base of a transistor Tr54 is left at the L level and hence a relay 52 fails to be excited. When the rotating shaft rotates reversely, the range of the H level at the terminal Q of the FF38 elongs and the H level state occurs four times only when at 78 deg. per one turn thereof. A counter 42 counts 12-13 and a setting signal is inputted into the FF46 to turn the terminal Q to the H level. Thus, the base of the Tr54 goes to the H level to excite the relay, thereby closing a contact 50.

Title: Throttle valve control device for internal combustion engine
Inventor: IBARAKI TOSHIKAZU
IPC: F02B1/04
Filed: 1993-05-21
Abstract: PURPOSE:To prevent occurrence of overrunning without bringing about abrupt deceleration shock and engine stall when abnormality occurs in a throttle controlling system. CONSTITUTION:A sub-throttle valve 8 and a main throttle valve 9 are arranged on in intake passage 9, and an output of an engine 1 is controlled by cooperatively driving them. The sub-throttle valve 8 is opened and closed by driving a step motor 11 according to an operation rate of an accelerator pedal 10. When abnormality occurs at the sub-throttle controlling system, a reference engine speed at abnormality near the engine speed detected at the time of occurrence of abnormality is computed, in place of the sub-throttle valve 8, as fail-safe treatment. Injectors 5A to 5D are intermittently driven such that the engine speed at the time of abnormality approaches the reference engine speed at abnormality. It is thus possible to prevent the engine speed from repeating hunting and abruptly changing, and prevent the engine speed from excessively lowering at abnormality.

Title: Semiconductor memory
Inventor: NEGISHI SATORU
IPC: G06F12/16
Filed: 1983-07-04
Abstract: PURPOSE:To simplify the structures of both hardware and software and to improve the general-purpose properties of a semiconductor memory, by using a threshold value setting circuit and a power supply voltage monitor circuit and actuating a read/write control circuit in response to the fall and rise of the power supply voltage. CONSTITUTION:The power supply voltage VCC of a system to which a memory is applied is fed to a power supply voltage monitor circuit 5. The circuit 5 detects the 1st threshold voltage for detection of break of power supply and the 2nd threshold voltage for detection of make of power supply which are applied from a threshold value setting circuit 6. In other words, the voltage VCC is detected when it falls less than the 1st threshold voltage and rises more than the 2nd threshold voltage respectively. Thus a read/write control circuit 4 is controlled. Then the circuit 4 reads out the contents of a buffer memory 3 when the break of the power supply is detected and writes them to a nonvolatile memory 2. Then the circuit 4 reads out the contents of the memory 2 when the make of the power supply is detected and writes them to the memory 3. In such a way, the threshold value is set to control the circuit 4. This can simplify the structures of both the hardware and software and improve the general-purpose properties of a semiconductor memory.

Filed: 1993-05-24
Abstract: PURPOSE:To realize a stable operation even in the transient state of a rising of a power supply without impairing the performance of a low noise amplifier such as a satellite reception converter. CONSTITUTION:The operation of low frequency oscillators (11-17) generating a negative power supply in the transient state of rising of a power supply for a satellite reception converter is started after a positive power supply 25 rises by 80%. Thus, the drain-source voltage of an FET 24 employed for the low noise amplifier is suppressed in the transient state of the rising of the converter power supply so as not to cause a state of negative resistance in the converter input thereby preventing instability of the operation of the low noise amplifier for a predetermined period after application of the power supply.

Title: Semiconductor device
Inventor: MIYATAKE HIDEJI
IPC: H01L27/118
Filed: 1990-05-10
Abstract: PURPOSE:To obtain a semiconductor device which enables a switch circuit to be switched without revising a mask by switching the switch circuit according to whether it is in test mode or not. CONSTITUTION:A switch circuit of a master slice is turned on or off depending on test mode or not. For example, since a signal TE is at low level and a signal - TE is at high level when the test mode is not selected in a shown delay circuit, transistors 11 and 13 are off and transistors 12 and 14 are on, thus realizing a four-stage delay circuit consisting of inverters 1-4. On the other hand, since the signal TE becomes a high level and the signal - TE becomes a low level in the test mode, the transistors 11 and 13 are on and the transistors 12 and 14 are off, thus achieving a two-stage delay circuit consisting of inverters 1 and 2. Thus, speed control of the delay circuit can be switched depending on whether the test mode is selected or not as in the above.
