Title: Module changeover type image compression and reproduction device
Inventor: UEDA HIROAKI
IPC: H04N19/625
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To provide the image compression and reproducing device in which a program optimum to a CPU and a digital signal processor(DSP) used at present is executed while having provision for a plurality of CPUs and DSPs regardless of a small program capacity. SOLUTION: An image compression means 4 receiving an image compresses three kinds of pictures which are an I picture being an in-frame code, a P picture being an inter-frame code in a forward direction only, and a B picture being an inter-frame code in two-way in forward and backward directions. In this case, a device control means 1 checks a CPU 2 used at present and program data 15 and discriminates whether or not a program employed for the image compression means 4 is a program optimum to the CPU used at present. When not optimum, the means 1 extracts a differential compression code representing a difference between a basic module and the CPU currently in use from the program data 15 and uses a code table 17 and a decoding means 16 to decode the differential code so as to combine an optimum module thereby generating an optimum program.  The image reproduction device conducts the similar processing to that of the image compressor.

Title: Method for raising seedling of apple fruit tree
Inventor: HARADA KIYOHARU
IPC: A01G1/06
Filed: 1989-10-02
Abstract: PURPOSE:To simply raise a seedling giving good fruits without generating a thickened portion at a grafting point and causing the breakage of the point by grafting a base tree, a fruit tree, a dwarf scion and a fruit tree in turn from the lower side. CONSTITUTION:A desired fruit tree 2 such as usually Fuji, Tsugaru or Orin apple, a dwarf scion 3 (intermediate tree) and a fruit tree 4, usually the same fruit tree as the fruit tree 2 in turn are grafted to a base tree 1. The sap of the tree stays at the grafting point between the dwarf scion 3 and the fruit tree 4 to produce a thickened portion, whereby the grafting point is weakened and readily broken. But the disposition of the fruit tree 2 also under the dwarf scion 3 does not cause the stay of the sap at each grafting point to prevent the generation of the thickened portion. The damage of the grafted tree caused by the breakage of the grafting point is prevented to give a good fruiting result.

Title: Carbon dioxide gas laser beam machining head
Inventor: EHATA KEIJI
IPC: B23K26/14
Filed: 1984-12-05
Abstract: PURPOSE:To strengthen a jet power and to prevent the adhesion of a melted matter on a lens by opening an assisting gas inlet port in the contact line direction close to the upper end, by providing a spiral line on the inner wall and by forming a gas spiral line stream in the conical nozzle connecting to a cylindrical part and condensing lens. CONSTITUTION:An assisting gas is passed in from the assist gas inlet port 4 opened in the contact line direction close to the upper end of a nozzle 3 and becomes a rotating stream in the nozzle 3. The assist gas becomes a spiral stream toward the lower part because of the upper part being partitioned by a lens 2 and a spiral line being provided on the inner wall of the nozzle. Due to the inner diameter of the conical nozzle 3 being reduced toward the outlet port the angular velocity of the rotation of the gas is gradually increased and the linear velocity is gradually increased as well. The gas jet velocity is therefore increased because of the rotation velocity having a bigger angular velocity being added to the increased linear velocity at the jet port. This is achieved almost without increasing the inner gas pressure nor gas flow quantity and the vapor of the melted matter invading from the nozzle 3 is completely stopped.

Title: Thrust washer
Inventor: KAWASAKI AKIYOSHI
IPC: F16C17/04
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To sufficiently supply lubricating oil to a sliding surface by improving the sliding surface of a thrust washer. SOLUTION: A plurality of recessed parts 3 are arranged in both the surfaces of the flat plate of a ring thrust washer 1. The recessed parts 3 are formed to residence parts for lubricating oil. The recessed parts 3 have an opening area of 50% for the surface of the flat plate of the thrust washer. A sliding operation state formed by joining the sliding surface (the surface of the flat plate) of the thrust washer to a mate member repeats the development of adhesion and a fine gap between them caused by axial vibration in terms of micro- observation. The development of the gap provides negative pressure to the gap. Thus, the lubricating oil resided in the recessed parts 3 is pulled out to the gap, supplying the lubricating oil to the sliding surface.

Title: Semiconductor switch
Inventor: MUKAI KANJI
IPC: H03K17/73
Filed: 1986-10-29
Abstract: PURPOSE:To decrease the leakage current at application of a forward voltage by using a PNPN semiconductor element so as to form the titled semiconductor switch and forming a mis-firing preventing circuit thereby improving the mis-firing preventing capability. CONSTITUTION:The semiconductor switch consists of the PNPN semiconductor element 1 and a cathode of a diode 8 and an emitter of a PNP transistor (TR) 2 are connected to its anode 5. The collector of the TR 2 is connected to a gate of an NPN TR3 via a diode 9. A forward voltage having a steep leading is applied between the anode 5 and the cathode 6 of the semiconductor element 1, then a transient current flows from the anode 5 to the TR 2 directly to turn on the NPN TR 3 via the diode 9. Then the P gate 7 and the cathode 6 of the semiconductor element 1 are short-circuited. Moreover, the leakage current of the TR 2 does not flow through the N-channel gate even at application of a constant voltage nor is amplified by the PNP junction of the semiconductor element 1. Thus, the mis-firing preventing capability of the semiconductor element 1 is improved.

Filed: 1986-10-30
Abstract: PURPOSE:To optimize an air-fuel ratio at engine start by opening an adjusting valve on an intake secondary passage until a predetermined time during the detection of a start operation at the time of high temperature starting, opening the valve until complete fuel combustion in a second predetermined time and closing the valve until complete fuel combustion after the second predetermined time.

Title: Reading method of information out of storage applying nonlinear oscillation
Inventor: AIDA TADAHITO
IPC: G02F1/35
Filed: 1990-09-27
Abstract: PURPOSE:To accurately and stably read out the information by reading out the information stored in a delayed feedback oscillator as a digital signal synchronous with an external reference clock signal. CONSTITUTION:The phase of oscillation is fixed to the phase of an external signal when the delayed feedback gain of a delayed feedback oscillator 2 is modulated by an external signal having a frequency approximate to an integer ratio of a free-running oscillation frequency. Therefore the phase of oscillation is fixed to the phase of a system clock signal S4 and the constant phase relation is always kept with the signal S4 when the frequency of the signal S4 is selected at a level approximate to an integer ratio of a free-running oscillation frequency of the oscillator 2. Then the stored information is read out as a digital signal synchronous with the signal S4. In such a way, the information can be read out with high accuracy and high stability.
