Title: Fiber reinforced metallic piston and manufacturing method thereof
Inventor: DOUNOMOTO TADASHI
IPC: C22C47/12
Filed: 1983-10-03
Abstract: PURPOSE:To secure such a piston as being lightweight and inexpensive as well as excellent in durability, by installing a cylindrical intermediate layer, composed of a metal, around a core part comprising light metals being compositely reinforced by a reinforced fiber as well as installing a hard metallic outer layer around the core part in addition. CONSTITUTION:A fiber molding body composed of a reinforced fiber 3 being made up into spiral form at a pitch angle theta+ or -65-+ or -70 deg. around an axis is formed, while this molding body is set up inside a cylindrical metallic intermediate layer 6 and, after being preheated and put in a mold, molten light metal is temmed in this mold. Then, a part composed substantially of light metals alone is removed from a solidified body obtained by solidifying the molten metal upon pressurization and then the circumference of the intermediate layer 6 is covered with a hard metal, thus an outer layer 7 is formed. Since rigidity and the rate of expansion are accorded with each other with a core part 1 and the intermediate layer 6, no peeling between them happens and, what is more, it comes to being so strong against the stress. Moreover, also in its manufacturing method, it is inexpensive and excellent in efficiency as well as in cohesion between the light metal, the reinforced fiber 3 and the intermediate layer 6.

Title: Composite molding method
Inventor: UENO HIDEKI
IPC: C08L83/04
Filed: 1994-08-05
Abstract: PURPOSE:To obtain a composite efficiently without using a mold rotating device by inserting, in between female and male molds, an other mold piece which forms a cavity for second injection of a liquid silicone rubber composition with a molded body. CONSTITUTION:A male mold 21 and a female mold 23 are assembled and attached to a two-color injection molding machine and clamped. A melted thermoplastic resin is injected into a formed cavity 31 from a first injection section 11, so that a thermoplastic resin molded body 41 is obtained. Next, another mold piece 22 is inserted so as to form a second injection cavity 42 in between a recess 24 of the mold piece 22 and the molded body 41 and a liquid silicone rubber composition is injected into the cavity 42 from a second injection section 12. The injected liquid silicone rubber is cured. The curing temperature is set to 60-250 deg.C and below a heat distortion temperature of the thermoplastic resin. Thus, a composite consisting of the thermoplastic resin and the silicone rubber having excellent dimensional precision can be obtained efficiently.

Title: Magnetic recording and reproducing device
Inventor: FUKUMURA YASUKAZU
IPC: G11B15/43
Filed: 1988-07-25
Abstract: PURPOSE:To enable the stable tape tension control in simple constitution without needing a large current by utilizing a discharge voltage of a capacitor for an on-off control of a solenoid. CONSTITUTION:The solenoid 26 of a self-hold type is turned on when a pulse signal is given to terminals 27 and 29, and is turned off when the pulse signal is given to terminals 28 and 29. By turning a power source 21 on, a charge and discharge circuit 24 is charged by the power source 21. Afterward, in a charge and discharge changeover circuit 25, a transistor (Tr) 30 is turned on when a control for the solenoid is given from a terminal 19 to a base of the Tr 30, and Trs 33 and 34 are turned on by a voltage from a power source 22. In addition, Trs 35 and 23 are turned off. Consequently, the circuit 24 is discharged, and a prescribed electric potential is given in between the terminals 27 and 29 of the solenoid 26, so that the solenoid 26 is turned on. Then, this on-state is maintained until a solenoid-off signal is given to a terminal 20. By this method, the stable tape tension control is feasible without needing a large current but with simple constitution.

Title: Intersymbol interference compensating circuit
Inventor: ASHIDA AKIRA
IPC: H04L25/40
Filed: 1980-12-27
Abstract: PURPOSE:To compensate an intersymbol interference by a digital circuit of the same type even if a transmission waveform and a transmission characteristic are different, by changing the number of discrimination and decision in accordance with a result of discrimination of the previous input data. CONSTITUTION:As for input data (a), a high frequency clock (b) and an NOT circuit 6 are brought to AND by an AND circuit 1. A counter 5 is set by a clock signal (c), and counts a high frequency clock of the circuit 1. A counting value deciding circuit 7 makes its output ''0'' in case when an output of a shift register 9 for storing data discriminated before is inputted, and a counting value of the counter 5 does not reach an optimum counting value that has been detected. Also, when said counting value has reached the optimum counting value, ''1'' is outputted, the circuit 1 is closed through the circuit 6, and after that, passing of the clock (b) is inhibited, and the constancy of an output of the counter 5 is held until the next signal (c) is inputted to the counter 5 and the counter 5 is reset. Also, an FF8 shapes a discriminating output of the circuit 7 by the signal (c) and obtains the discriminating output 10 of a binary NRZ code.

Title: Method for estimating ground resistance corresponding to burial depth of bar-shaped ground electrode
Inventor: WAKE TOSHIO
IPC: G01R27/20
Filed: 1994-07-15
Abstract: PURPOSE:To determine the burial depth of a bar-shaped ground electrode by calculating a potential difference/current ratio at each point using Wenner's our-electrode method while varying in steps the interval between electrodes, and obtaining an estimated resistance value through the multiplication of each value by a constant determined by the diameter of the bar-shaped ground electrode, and estimating this value to be the ground resistance of the ground electrode buried to a depth matching the electrode-to-electrode interval. CONSTITUTION:Four point electrodes C1, P1, P2, C2 are arranged on a straight line on the surface of the ground at intervals a, and a direct current l is passed between the electrodes C1, C2 to measure a potential difference V between the electrodes P1, P2. When the diameter and length of a bar-shaped ground electrode are D and L, respectively, the distance between the upper end of the ground electrode and the surface of the ground is t and the length of the ground electrode corresponding to a hemispherical electrode having a diameter of 1m is L1, then a=l+t so that the ground resistance R of the ground electrode is R = (1/1.41) (L1+t) (V/I)=C(V/I), the constant C determined by the diameter D. Therefore, the interval a is varied in steps to calculate V/I at each point, and the value of V/I is multiplied by the constant C to obtain an estimated resistance value, and this value can be estimated to be ground resistance when the ground electrode is buried to a depth matching the interval a.

Title: Spitted dimpling and spitted dumpling packaging body
Inventor: HAMADA KICHIJI
IPC: A23L7/10
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To obtain spitted dumpling readily edible even in women or children having small mouths and readily handling without making hands dirty. SOLUTION: Two dumplings 3 and 3 are pierced into a spit 2 so as to occupy nearly half of length of the spit. The length of the spit 2 is preferably 8cm and the each dumpling 3 has preferably a sphere with 2cm diameter. In this case, two dumplings 3 and 3 are pierced so as not to protrude the top of the spit. As a result, since grip part 2 having 4cm length is left, the dumpling can readily be handed by adult as well as child. When spitted dumpling having sauce is housed in a tray type case, the dumpling is preferably housed in a state inclined in vertical direction so as to turn the grip part 2a upward, because the grip part 2a is not made dirt even if the case is largely inclined.  Further, deviation of sauce is prevented even when the case is slightly inclined by partitioning the interior of the housing case into a part for housing the dumpling and a part for housing the grip of the spit.
