Title: Radio receiver
Inventor: MIYAZAKI YOSHIAKI
IPC: H04B1/26
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To display the name of a selected station immediately after channel selection by comparing a detected distribution of broadcast frequencies with a stored distribution of broadcast frequencies so as to specify the area to which a radio wave is tuned at present and to specify the name of the broadcast station. SOLUTION: In the case that e.g. frequency 80.0 MHz of an FM broadcast program is received at present, a control section repeats a direct operation of checking a search object frequency higher than the received frequency until a broadcast frequency is detected and results in receiving a frequency 81.3 MHz, and then stores the received frequency in a memory. Then the control section repeats a direct operation of checking a search object frequency lower than the received frequency until a broadcast frequency is detected and results in receiving a frequency 79.5 MHz, and then stores the received frequency in the memory. Thus, a combination of the three frequencies; the received frequency 80.0 MHz and the frequencies as results of SD checking 81.3 MHz, 79.5 MHz, and a frequency list of broadcast stations having been stored in advance in the memory are compared.

IPC: H02K3/34
Filed: 1986-08-01
Abstract: PURPOSE:To prevent the intrusion of a coil between a pole nose section in a core and insulating paper by forming an insulating-paper holding section at the pole nose section in the core. CONSTITUTION:Insulating paper 4 is inserted into a slot 3 for a core 1, and spool end plates 10 are disposed to both end surfaces of the core 1. The insulating paper 4 intrudes to a yoke central section 13 for the core 1 and a hook- shaped insulating-paper holding section 14 shaped to a pole nose section 8 at that time, and the insulating paper 4 is fixed. Winding-start wires 5a, 5b are fastened previously, and a coil 2 is wound on a spool section 11 only by the fixed number of turns. Since the insulating paper 4 on the bottom 9 of a slot is received by a pad section 12 in this case, the insulating paper 4 is not deformed even by tension on winding. Winding-end wires 6a, 6b are wound on an approximately T-shaped winding section 15, thus forming a field system assembly.

Title: Device for removing water drop
Inventor: OKADA SHOJI
IPC: B60R1/06
Filed: 1988-07-21
Abstract: PURPOSE:To efficiently remove water drops deposited on the whole mirror by electrifying a piezeoelectric oscillator installed on the backside of the mirror and generating both longitudinal and lateral waves on the mirror. CONSTITUTION:A piezoelectric oscillator 20 in which electrodes are formed in a body with both sides of an electrostrictive element is installed on the backside 11a of a board type mirror 11. As a resonance frequency of a lateral effect mode is applied to the piezoelectric oscillator 20, the mirror 11 is repeatedly bent generating uniform lateral waves with a large amplitude on the whole mirror 11 to remove water drops deposited on a reflecting face 11b. As a resonance frequency of a longitudinal effect mode is applied, longitudinal waves with a large amplitude are generated on the fixed portion of the piezoelectric oscillator to remove water drops on the fixed portion of the piezoelectric oscillator which failed to be removed by the lateral effect mode. Thus, by generating both longitudinal and lateral waves, water drops deposited on a every portion of the reflecting face can be efficiently removed.

Abstract: PURPOSE:To perform epitaxial growth without any crystal defect by providing an amorphous insulating object including F on the surface of the insulating object where a semiconductor film is in contact with before performing an epitaxial semiconductor thin film or rounding one part of a corner of the insulating object including F. CONSTITUTION:An SiO2 layer 2 is formed by providing a two-layer mask of an SiO2 18 and an Si3N4 19 to a single crystal Si 1 and then oxidizing it. F ions are implanted at an appropriate energy to form an amorphous insulating object (SiO2:F) 20. The mask is removed, an SiO2 layer is etched, and a substrate opening 3 which becomes a core crystal is exposed. Then, using SiH2Cl2+HCl+ H2, a single-crystal Si thin film is subject to gaseous phase growth from the opening 3 at a specified pressure and temperature. In this case, if HCl concentration is set appropriately, accumulation of poly Si on the amorphous insulating object 20 including F is prevented. If the temperature of epitaxial growth is selected appropriately, F separation from the insulating object layer 20 is restricted and a single-crystal epitaxial film without any crystal defect can be obtained, thus forming a semiconductor device with improved characteristics.

Title: Automatic pouring device
Inventor: SAKAGUCHI YOSHIHARU
IPC: B22D39/06
Filed: 1983-09-29
Abstract: PURPOSE:To enable optimum pouring with a simple device without requiring a large-scale device with a device provided with a means for driving the stopper of a nozzle in the bottom at the top end of a spout-shaped tap hole of which the molten metal surface is controlled by controlling steplessly the stopper drive. CONSTITUTION:When the input current value of a DC power source 31 is adequately varied and is passed to a pneumatically operated controller 32, the current is transduced to an air pressure by as much as the current value in the controller 32. The piston rod 8a of an air cylinder 8 is vertically moved by such air pressure. The displacement of the vertical movement is transmitted via a feedback lever 33 to the controller 32 and the rod 8a is stopped in the position balanced with the power generated by the input current. The vertical stroke of the cylinder hence the vertical driving stroke of the stopper 7 of a nozzle 6 in the bottom at the top end of a spout-shaped tap hole coupled directly to the rod 8a are thus steplessly controlled. As a result, the molten metal is poured with good accuracy in an optimum pouring pattern into various casting molds having intricate shapes and having high or low pouring rates.
