Title: Engine starting device
Inventor: TOZAWA SATORU
IPC: F02N11/08
Filed: 1994-04-28
Abstract: PURPOSE:To provide an engine starting device wherein an engine is started by discharging, to a starter, the charge of a condenser having large capacity. CONSTITUTION:Resistances 5, 6 for balancing voltage to be connected in parallel to each condenser 7, 8 are connected to each other through relaies 12, 13. A pressure rising circuit 3 is operated from the switch 1-2 of a key switch part 1 during the starting period of an engine so that the condensers 7, 8 are charged, however at this time, voltage is balanced by energizing the relaies 12, 13 by voltage from a battery 2 through a switch 1-2 so that the resistances 5, 6 are connected in parallel. Charge from a generator part 9 to the condensers 7, 8 is performed when the engine is started and the generator part 9 starts to generate electricity, however at this time, the voltage is balanced by energizing the relaies 12, 13 by the voltage from the L terminal of the generator part 9. The relays 12, 13 are OFF when the charge is performed from neither the battery 2 nor the generator part 9 so that the condensers 7, 8 do not discharge their power through the resistances 5, 6.

Title: Contact bending rolling mill
Inventor: MIYASAKA KIYOTO
IPC: B21B45/06
Filed: 1984-06-05
Abstract: PURPOSE:To permit the use of a high-speed side work roll having a small diameter as it is even if the width of a rolling material increases in a descaling mill having two work rolls which rotate at different speeds by resting a backup roll for supporting the high-speed side work roll in a specific position. CONSTITUTION:The rolling material S is wound on the upper work roll 1 rotating at a highspeed and is subjected to descaling rolling between said roll and the lower work roll 3 rotating at a low speed. The rolling load increases when the width of the material S increases and therefore the capacity of a bearing 2 to support the roll 1 needs to be increased. The diameter of the bearing 2 increases inevitably and the diameter of the roll 1 increases correspondingly. The backup roll 5 for the upper work roll is rested after the position thereof is shifted by an angle theta from the line connecting the centers of both work rolls 1, 3, then the force component W1 of the rolling load F is supported by the bearing 2 and therefore the use of the bearing 2 and the roll 1 having the small diameter as they are is made possible.

Title: Construction method for agitated mixed reinforcing body
Inventor: TATEYAMA MASARU
IPC: E02D3/08
Filed: 1993-04-20
Abstract: PURPOSE:To make a rod function as a load resistant body by leaving and fixing the rod in an agitated mixed reinforcing body formed by agitating and mixing excavated soil and a solidifying body in the ground while excavating the ground. CONSTITUTION:A solidifying material is supplied through a shaft passage together with excavated soil by an agitating vane 13 of an excavating agitating hollow rod 1, and an agitated mixed reinforcing body 2 is constructed. When it reaches a prescribed depth, the rod 1 is separated from a boring machine 3, and is left in the reinforcing body 2. After the reinforcing body 2 is hardened, a rotary shaft 11 of the reinforcing body 2 projecting to the ground surface side is fixed to a concrete wall body 5 or the like. In this case, an excavating vane 12 and the agitating vane 13 of the excavating agitating hollow rod 11 function as a load resistant body to check slipping-out of the rod 1, and exhibit extremely large pullout resistance force. Thereby, since the possibility that agitated mixed soil before it is hardened slips out of a hole together with the excavating agitating hollow rod is eliminated, it is constructed safely while avoiding looseness of the peripheral ground or ground subsidence.

Title: Electronically controlled fuel injection process and equipment in internal combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/06
Filed: 1981-07-23
Abstract: PURPOSE:To prevent the engine from its unstable revolution and fuel wastage in such a way that when damping of incremental values is done after starting correctly in response to the warming up condition in the engine, the damping is constituted to be damped every synchronous injection of fuel. CONSTITUTION:When injection time of an injector 36 is controlled by means of an electronic control circuit 38 which takes output signals in from an air-flow meter 12, a cooling water temperature sensor 16, and other detectors, incremental compensation is done as mentioned hereinafter after starting. In other words, before everything, discrimination is done for the advisability in the condition after starting through the fact that whether or not the number of revolution in the engine exceeds the determined number of revolution (for example, 500 r.p.m.). Then, when discriminating the condition after starting, the incremental values are found after starting from the relationship between the then cooling water temperature and the incremental compensation factor in its initial value. Further, discrimination is done to the fact that whether or not injection flags in response to the synchronous injection are set to 1, and at the time of the synchronous injection, while the incremental compensation factor after the stated starting is damped as much as about 0.2% every time, damping of the incremental values are gradully promoted.

Title: Liquid crystal optical device
Inventor: NAKAMURA HARUO
IPC: G02F1/139
Filed: 1981-07-24
Abstract: PURPOSE:To improve high-speed response characteristics, by executing a treatment so that the orientation directions of liquid crystal molecules on the surface of 2 substrates become parallel with each other, and also placing the polarization plane of a polarization plate at 45 deg. with respect to said orientation directions, as to a liquid crystal panel using an optically activated nemtic liquid crystal which generates dielectric transition by low frequency. CONSTITUTION:An optically activated nematic liquid crystal composition whose torsion pitch is about 4mum is used, and the surfaces of the upper and lower substrates are orientation-treated in parallel with each other. In this case, the liquid crystal takes a 360 degree torsion structure to 3-5mum thickness of a liquid crystal layer. Both upper and lower outside polarization plates are placed at positions where the polarization direction is + or -45 degrees with respect to the orientation direction. As a result of measurement of a response by applying a driving signal to said plates, a delya of start of transmission has annihilated entirely, as compared with a conventional case, and a quick response has been shown. Also, in case when the planes of polarization of 2 polarization plates crossing at right angles to each other have been placed at 45 degrees with respect to the orientation direction of the substrate, the best response characteristic 70 has been obtained.

Title: Feeding device for gold wire for bonding
Inventor: KOIZUMI TAMOTSU
IPC: H01L21/60
Filed: 1990-05-02
Abstract: PURPOSE:To contrive the improvement of the corrosion resistance, wear resis tance and conductivity of contacts by a method wherein the contacts are formed of a noble metal, such as an Ag-Pd alloy. CONSTITUTION:An Au wire A unrolled from a spool S goes through contacts 1 to 3 made of an Ag<40>-Pd<60> alloy, is led to a capillary C, the air is jetted on the Au wire A between these contacts 2 and 3 and the Au wire A is made to loose. While the Au wire A is separated from the contact 2, a feed motor M is rotated, an Au wire A is unrolled from the spool S and when a looseness of the Au wire A is increased and the Au wire A comes into contact with the contact 2, the rotation of the motor M is made to stop and the unrolling of the Au wire A is stopped. In this case, as the contacts are formed of a noble metal, such as an Ag-Pd alloy or the like, an oxidation is not generated on the surface of the contacts even if a fine rubbing operation is repeated to the contacts made of a noble metal by the Au wire. Thereby, the improvement of the corrosion resistance, wear resistance and conductivity of the contacts is contrived.
