Title: Manufacture of natural stone-like concrete product
Inventor: ADACHI MICHIHIRO
IPC: E01C19/43
Filed: 1988-08-26
Abstract: PURPOSE:To manufacture natural stone-like concrete products by a method wherein a mold, having appropriate patterns on its surface, made of elastic material is laid on half-dried concrete surface and surface treatment is given with pressure applied by vibration given to the mold for a certain period of time and the mold is removed afterward. CONSTITUTION:Concrete 1 is placed on the surface of the ground to be treated for making such facilities as parks, tree-lined streets, promenades, parking areas, poolside areas and others. A mold 2, having appropriate patterns like natural stones, made of elastic material is laid over the concrete while it is still under half-dried condition, and the concrete is pressed with vibration given to the mold for a certain period of time. Thereby, surface treatment is applied to the concrete 1. With a lapse of a certain period of time after application of pressure, hardening of the concrete 1 starts and the mold 2 is removed afterward. With such procedures, natural stone-like concrete products can be simply and easily manufactured.

Title: Production of magnetic head
Inventor: KUMAKIRI MICHIO
IPC: G11B5/127
Filed: 1983-11-11
Abstract: PURPOSE:To obain stably a satisfactory head gap by facilitating easy positioning for the 1st and 2nd reinforcement plates as well as both core halves in a head assembly mode by butting a pair of core halves held between both reinforcement plates and furthermore avoiding revolutions of those core halves when they are butted together. CONSTITUTION:A frame body 5 contains the 1st and 2nd reinforcement plates 1 and 2 as well as core halves 3 and 4 which are held between the plates 1 and 2 with butting faces put opposite to each other. Then a contact is obtained between the outer face 52a of a rear side 52 and a cover plate 6, and a hollow part corresponding to projected part 56 of a side part 53 is pushed more inside with a holder plate 7. Thus the halves 3 and 4 separated from each other as shown by broken lines are moved within the surfaces of both plates 1 and 2 to be attached close to each other. Under such conditions, the resin serving as a binder is impregnated and hardened. Then a rounding process is carried out to protrude a tape touching face 8. Thus a magnetic head is obtained. In such a way, the yield is improved for the butting process of head cores.

Title: Combustion flame detector for burner
Inventor: NOMARU NORIKI
IPC: F23N5/24
Filed: 1988-08-26
Abstract: PURPOSE:To prevent a burner from being stopped during control due to the mixing-in of air by suspending a control based on a flame sensor, until a load current for a fuel pump detected by a current detector reaches or exceeds a predetermined value. CONSTITUTION:During a drying operation, an operating load current for a fuel pump 1 for supplying a fuel to a burner 5 is detected by a current detector 2, and is compared with a current set and stored in a combustion controller. A control based on the result of detection by a flame sensor 3 for sensing a combustion flame generated from the burner 5 is suspended until the detected current reaches or exceeds the set and stored current. When the detected current reaches or exceeds the set and stored current, the control based on the result of detection by the sensor 3 is started. For example, when the current detector 2 is detecting a current not less than the set and stored current but the combustion flame is not detected by the sensor 3, it is judged that misfire is caused by a trouble at a part other than the fuel pump 1, and the burner 5 is automatically stopped under control by the combustion controller.

Title: Optical head device
Inventor: TAKAHASHI NAOMASA
IPC: G11B7/085
Filed: 1992-08-10
Abstract: PURPOSE:To provide an optical head device capable of high-speed access. CONSTITUTION:A head unit 4 is so supported that it can be moved in the diametral direction of an optical disk by four guide rails 30a to 30d arranged around the centroid position of the head unit 4. Since guide rails 30a to 30d are arranged at intervals narrower than the width of the head unit 4, secondary resonance probably brought about at the time of moving the head unit 4 at a high speed is practically suppressed. Consequently, the optical head device capable of high-speed access is obtained.

Title: High frequency amplifier circuit
Inventor: MIWA MAMORU
IPC: H03F3/193
Filed: 1994-09-08
Abstract: PURPOSE: To prevent an oscillation and to obtain a stable high frequency amplifier circuit by connecting an inductor between the source of each FET forming a semiconductor amplifier element and ground and connecting the inter-source of an FET via a resistance. CONSTITUTION: The high frequency signal via an input side matching circuit 11 is amplified by FETT1 and Tn connected in parallel. A ground connection is performed for each of the sources S1 to Sn of the FETT1 to Tn via inductors L1 to Ln , the input impedance of the FETT1 to Tn becomes low and the constitution of the circuit 11 is facilitated. Resistances R1 to Rn-1 are connected between the terminals of the sources S1 to Sn . When the oscillation by the feedback via the drain gates of an FET is generated, a difference is generated in the high frequency voltage in the sources, current flows in the resistances R1 to Rn and the oscillation is suppressed. When a circuit operates as a high frequency amplifier circuit, the source high frequency voltage of the FET is equal, current does not flow to the resistances R1 to Rn and loss, etc., is not generated.  Thus, the circuit becomes the stable high frequency amplifier circuit, preventing the oscillation.
