Title: Core bit
Inventor: OGATA SEIYA
IPC: E21B10/02
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To inhibit the partial wear of diamond tips besides the maintenance of the smooth flow of cooling water in a core bit, in which a plurality of the diamond tips are installed at the front end of a pipy base metal. SOLUTION: The difference of chip ratios on the outer circumferential side and inner circumferential side of a base-metal front end can be reduced besides the maintenance of the smooth flow of cooling water by combining fan-shaped diamond tips 12b, in which the length of circular arcs on the inner circumferential sides is made shorter than that on the outer circumferential sides, and rectangular diamond tips 12a, in which the length of circular arcs on the inner circumferential sides is made the same as that on the outer circumferential sides, in the shape of a drilling working surface. Accordingly, the partial wear of the diamond tips is inhibited, cutting quality is maintained for a prolonged period, and the lifetime of the core bit can be lengthened.

Title: Photosensitive material
Inventor: TAKAHASHI RYUICHI
IPC: G03F7/028
Filed: 1987-04-10
Abstract: PURPOSE:To obtain a picture image capable of providing a distinct picture image for a long time by incorporating a heat-fusible compd. having 30-250 deg.C m.p. and having a polar group into inside and outside of microcapsules, respectively, constituting a photosensitive layer. CONSTITUTION:A heat-fusible compd. having a polar group and 30-250 deg.C m.p. is incorporated into the inside and outside of microcapsules, respectively, constituting a photosensitive layer. Thus, a basic material diffuses sufficiently into the inside of the microcapsules in the stage of development, so a polymn. reaction in a part where a latent image of silver halide is formed proceeds smoothly. Moreover, since the heat-fusible compd. causes scarcely reaction at room temp., there is no fear for impairing superior preservation stability of a photosensitive material constituted by distribution the basic material to the outside of microcapsules. By this constitution, a distinct picture image is obtd. even after preserving for a long time or under severe conditions.

Title: Injection nozzle
Inventor: SAKURAI NORIYUKI
IPC: F02M61/10
Filed: 1986-04-18
Abstract: PURPOSE:To prevent the delay of ignition due to the excessive injection by forming a fuel passage into a needle valve installed in free elevation into a nozzle body and introducing the fuel oil corresponding to the lift of the needle valve into an injection port from a fuel chamber, thus permitting the injection of the fuel corresponding to the operation state of an engine. CONSTITUTION:Fuel oil is supplied into a fuel chamber 3 through the fuel feeding passage 7 in a nozzle body 1, and a portion of the fuel oil is sent into an injection port 6 through the first fuel passage 12 according to the supplied fuel oil pressure. At the same time, the fuel oil pressure is allowed to act into the first throttle part 10, and a needle valve 2 is lifted to the opening direction. Therefore, the fuel oil sent in the first fuel passage 12 is jetted from the injection port 6. At the same time, an opened hole 13 is allowed to communicate to the fuel chamber 3 according to the lift of the needle valve 2, and fuel oil is introduced into a valve seat 5 from the fuel chamber 3. Therefore, the total quantity of the fuel oil which passes through the first and the second fuel passage 12 and 15 is jetted from the injection port 6. Therefore, even if the fuel oil pressure sharply rises, the sharp lift of the needle valve 2 is suppressed.

IPC: F02D45/00
Filed: 1979-07-13
Abstract: PURPOSE: To control vectors to be controlled such as air-fuel ratio, ignition timing and rate of recirculation of exhaust gas correctly, by storing a state function modelling the dynamic characteristics of respective sensors into a computor, and making an effective use of the state function.  
     CONSTITUTION: Dynamic characteristics of various engine controlling means and engine itself are stored in a computor 10, and relationship between control inputs and control outputs is detected by a computor model. For instance, a state function dynamically indicating the relationship between fuel supplied from carburetor and the amount of fuel in engine 9 and the signal of an exygen sensor is prepared and stored in computor 10. Here, if the model of this state function is in conformity with the engine condition, it is judged that the air-fuel ratio is controlled correctly. However, if the rate of fuel supply is changed due to deterioration of a controlling means, for instance, acceleration pump of carburetor, the extent of this deterioration is detected from the model of state function and proper correction is applied to the mechanism of acceleration pump.

Abstract: PROBLEM TO BE SOLVED: To drastically reduce waiting time for customers and to shorten the processing time of one transaction by identifying receiving money to determine a received amount and also immediately receiving money to be temporarily retained as change money at the time of ascertaining the received amount. SOLUTION: A controlling part 112 first decides a required receiving amount based on an amount such as a sales amount and a transfer amount which are inputted by an operating part 110 and sends a money receiving command to money receiving and paying devices 1 and 2. When an operator performs money receiving approval instruction, the part 112 compares the required receiving amount with a received amount and compares the denomination of received money with the denomination of paying money to pay as change when there is change. When the denomination of paying money is lower, the paying command of the change and the storage command of temporarily retaining money are simultaneously sent to the devices 1 and 2.  The devices 1 and 2 parallelly perform paying processing which throws necessary change to money paying parts 25 and 10 and storage processing which stores money retained in collectively and temporarily retaining parts 36 and 102 in different denomination storing parts 37 to 39 and 103.

Title: Method and device for preventing oscillation of forge-welded steel pipe skelp
Inventor: KIKUCHI SHIYOUICHI
IPC: B23K20/00
Filed: 1984-05-07
Abstract: PURPOSE:To prevent the uneven heating of skelp edges by adjusting the angle of guide rolls provided in the outlet of a heating furnace in the stage of producing a forge-welded steel pipe by heating locally the edge parts after heating the skelp of a blank material and forming the material to a tubular shape then subjecting the skelp edges to continuous press welding. CONSTITUTION:The skelp 8 of the blank material is heated in the heating furnace 11 and is guided by a set of guide rolls 2, 2 which are provided in the outlet of the heating furnace and cross each other. The scale of the skelp edges is removed by the air blown out of edge blows 12 and the skelp is preheated and is then formed into a tubular shape by forming rolls 13. Only the edge parts of the skelp are again locally heated by the oxygen blown out of a welding horn 14 and are press-welded by forge-welding rolls 15, by which the pipe is manufactured. The angle of the rolls 2 is adjusted in this case to prevent the uneven heating owing to the welding hole of the skelp edges to be forge-welded. The forge-welded steel pipe having excellent quality is thus produced.

Title: Ultrasonic level meter with switch output
Inventor: TANAKA TOYOHIKO
IPC: G01S15/04
Filed: 1979-07-14
Abstract: PURPOSE:To prevent the damage, erroneous indication and malfunction of a meter by providing upper-limit and lower-limit gate circuits that permit a received pulse to pass through them in accordance with the upper-limit and lower-limit levels of a reservoir level and then by performing switching by outputs of those gate circuits. CONSTITUTION:A reference pulse from reference-pulse generating circuit 1 is sent as an ultrasonic wave pulse to a tank bottom part by way of transmitter 6 and its reflected wave is detected through receiver 7, so that so far as the received pulse is normally obtained, a meter displays the normal level of the contents of the tank. The reference pulse, on the other hand, is input to the 1st and 2nd monostable multivibrators 13 and 14, which outputs upper-limit and lower-limit gate pulses respectively. Since R-S flip-flop 2 is supplied with the trailing edge of the lower- limit gate pulse in every period of the reference pulse, flip-flop 2 is reset at fixed timing without fail even when the reflected wave is interrupted, so that an excessive input to the meter can be prevented.
