Patent JP-H0821550-A (JP)
Title: Flow control valve
Inventor: ISHII TETSUYA
IPC: B62D5/07
Filed: 1994-07-06
Abstract: PURPOSE:To provide a flow control valve having a high pressure chamber and back pressure chamber partitioned by a spool valve in which application of a surging pressure on a pump is certainly prevented by forming a communication path to put the back pressure chamber in communication with a drain port and by furnishing a surge valve which opens only at the cold start of the pump in the communication path. CONSTITUTION:When a pump 8 is to be started at a low temp., the pressure in a high pressure chamber 4 rises because a working liquid has a high viscosity at a low temp. and is difficult to pass through an orifice 11. Therefore, the valve element 17 of a surge valve 23 is separated by a spring 20 from the valve seat 16 and pressed to the other end of a valve accommodating chamber 14. Thereby a back pressure chamber 5 is in communication to a drain port 7 via a communication path 22, and the pressure in high pressure chamber 7 is released to the drain port 7. The surge valve 23 is closed other than when the pump 8 is in low temp. starting, and after its being opened, and the differential pressure about the orifice 11 acts on a spool valve 3 to cause its moving in compliance with the size of the differential pressure, and thus the rate of supply flow of the working liquid to a power steering device, etc., is controlled properly.

Title: Magnetic recording medium
Inventor: ISHIKAWA AKIRA
IPC: G11B5/73
Filed: 1993-07-16
Abstract: PURPOSE:To improve both the durability and the recording/reproducing characteristics of a magnetic recording medium by a method wherein an intermediate layer made of fine magnetite powder having a low coercive force is formed on a substrate and a magnetic layer whose thickness is not larger than a specified value is formed on the intermediate layer. CONSTITUTION:A magnetic recording medium is composed of a substrate, an intermediate layer which is formed on a substrate and is made of magnetite powder which has an average particle diameter not larger than 0.2mum and a coercive force not larger than 150Oe and a binder and a magnetic layer which is formed on the intermediate layer and has a thickness not larger than 1mum. The magnetic layer is made of one of needle-shaped metal powder, needle-shaped cobalt-coated iron oxide powder and hexagomal ferromagnetic powder and binder. If the average particle diameter of the magnetite powder of the intermediate layer exceeds 0.2mum, the surface performance of the magnetic layer formed on the intermediate layer is deteriorated. If the coercive force of the magnetite powder exceeds 150Oe, the recording/ reproduction characteristics of the magnetic layer is hindered and, especially radio frequency characteristics are degraded.

Title: Image reader
Inventor: HORIE MIKIO
IPC: G02B7/36
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To make an entire reader small by utilizing an image forming system for image pickup as it is so as to detect the distribution of contrast and controlling an auxiliary light so as to focus the image forming lens. SOLUTION: CPU 300 is operated as follows: at first, the storage signal of an image sensor 16 is read for a default prescribed storage time, and data equivalent to a prescribed bit around a center picture element in the main scanning direction are received as a discrimination object. Succeedingly, a maximum luminance Bmax and a minimum luminance Bmin are detected from the luminance of a discrimination object to obtain the difference of the both and the result is written in a 1st luminance difference variable Bsub1 . Then the contents of the Bsub1 are transferred in a 2nd luminance difference variable Bsub2 to reverse a lens drive motor 60 thereby decrementing a lens pulse counter Paf . The operation is repeated in the case of Paf <0 and Bsub21 <Bsub1 . When the relation of the Bsub21 >Bsub1 is discriminated, the focusing is discriminated at the position of the image forming lens.  When the focusing cannot be detected in a moving range of the lens, an auxiliary light is lighted to drive a motor 60 forward and the similar discrimination to above is conducted.

Title: Semiconductor integrated circuit device
Inventor: INOUE MICHIHIRO
IPC: H01L21/822
Filed: 1980-12-16
Abstract: PURPOSE:To effectively prevent the latch-up in a bipolar IC by providing a resistance region between a region becoming an emitter of a parasitic transistor and a power source and always holding the emitter potential of the transistor at a voltage lower than the power potential. CONSTITUTION:In a bipolar IC shown, parasitic transistors Qn, Qp form a parasitic capacitance, causing a latch-up. Accordingly, a p type region 8 connected directly to Vcc is connected via an n<+> diffusion region 15 formed simultaneously upon diffusion of an emitter. That is, an n type resistor Rs 27 is connected in series between the region 8 becoming the emitter of the parasitic transistor Qp 23 and the Vcc, thereby always holding the potential of the region 8 lower than the potential of the Vcc. Thus, even if a latch-up occurs, causing the Qp 23 to become conductive, the voltage is dropped by the Rs 27, thereby eliminating the forward between the emitter and base of the Qp 23. Accordingly, the latch-up is not actually produced.

IPC: C12Q1/06
Filed: 1988-07-18
Abstract: PURPOSE:To count only bacteria in distinction from foreign matter by making the diameter of a laser beam spot larger than that of a colony and judging the magnitude of the voltage obtained by the selective detection of the fluorescence emitted from the colony. CONSTITUTION:The laser beam from a laser beam source 1 is converged to a spot by a converging lens 3. As the lens 3, one making the diameter of the spot larger than the average diameter (several ten mum) of a colony, that is, bringing said diameter to about 100mum is used. The stained colony and foreign matter on a membrane filter 4 are scanned by laser beam to emit fluorescence which is, in turn, inputted to a photomultiplier tube 9. The light detection voltage of the photomultiplier tube 9 is inputted to a peak value detection circuit 12 to detect a peak value. In a judge part 13, it is judged whether said peak value is within a range from a preset upper limit Vmu (the peak value of the light detection voltage of the max. colony) to a preset lower limit Vd (the peak value to the min. colony) and, when the peak value is within said range, the light detection voltage is judged to be one due to a colony to count the colony and the count signal is outputted.
