Abstract: PROBLEM TO BE SOLVED: To simplify the adjustment of the coupling of a laser beam to an optical fiber by connecting a easing housed as light source to the optical fiber for guiding the laser beam through a spherical coupling adjustment means. SOLUTION: The linked state of a laser resonator part 34 and a laser beam incident end 22a affects the incidence efficiency of a laser beam to a laser beam incident end 22a from the laser resonator part 34.

Title: Receiver
Inventor: KAKIHARA EISHIN
IPC: H03J7/28
Filed: 1981-11-07
Abstract: PURPOSE:To prevent an automatic sweep from stopping owing to a noise, etc., by providing a PLL synthesizer channel selecting circuit, FM stereophonic demodulator, threshold value switching circuit, and D-FF, and performing stereophonic reproduction even if the level of a received signal is relatively low. CONSTITUTION:A D-FF9 is added and only when a station searching signal is generated during channel selection, the reproduction mode of a stereophonic demodulator 5 is set to auto mode. Consequently, when the level of the station searching signal is low during preset channel selection, the reproduction mode is set to monaural mode, so that no change of the reproduction mode is caused between stereophonic reproduction and monaural reproduction. In addition, it is unnecessary to provide hysteresis characteristics to a circuit for generating the station searching signal. Further, a PLL controller 7 generates a sweep channel selection signal during sweep channel selection and according to the presence of said signal, threshold values of the station searching signal are changed between high and low to perform stereophonic reproduction even the level of the received signal is relatively low while preventing the stopping of an automatic sweep due to a noise and a disturbance signal.

Title: Hot-water heating system
Inventor: TAKAHASHI TOSHIHIKO
IPC: F24D3/00
Filed: 1993-07-20
Abstract: PURPOSE:To attain a saving of fuel and comfortable cooling and heating by a method wherein a hot-water boiler is controlled so that the temperature of hot-water flowing into a cistern falls by a specified value until restarting-up of a fan after it is once stopped. CONSTITUTION:An indoor-side controller 7 restarts a fan 4 when hot-water temperatures detected by a hot-water temperature sensor 6 reach a specified value, and sends hot-air into a room. When the temperature inside the room detected by a temperature sensor 5 exceeds a set point, the fan 4 is stopped, and when the temperature inside the room drops to a specified value or lower, the fan 4 is restarted. The information on stoppage and restart-up of the fan 4 is transmitted to an outdoor-side controller 12. The outdoor-side controller 12 controls a hot-water boiler 8 so that hot-water is kept at 85 deg.C, for example, while the fan 4 is in operation and at 65 deg.C while the fan 4 is in stoppage state. Thereby, fuel can be saved and the comfort can be improved as the temperature of supply air gently rises when the fan 4 is restarted.

Title: Guide roller, mold for injection molding for molding the guide roller and injection molding method
Inventor: TAKEDA YOSHINOBU
IPC: G11B15/60
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain a guide roller formed with prescribed surface roughness on the outer peripheral surface of molded goods without using mechanical polishing. SOLUTION: A molten resin 13 is injected and packed into the cavity A of molds clamped under a low pressure via a sprue 3, a runner 4 and a gate 5. The molten resin in the cavity A flows backward to the gate 5 side as shown by an arrow and the outer peripheral surface of the molded goods 1 and the gate 5 are disconnected when a cavity sleeve 8 is lowered by high pressure until the sleeve passes the gate 5. The surface roughness of the surface 11 for forming the outer periphery of the molded goods of a moving side mold plate 7 is set at 0.2-S and is transferred to the outer peripheral surface of the molded goods 1. Since there is no trace of the gate on the outer peripheral surface, the use of the molded goods 1 by mounting the molded goods as they are on a projector, etc., is possible.  Since the high-pressure mold clamping is executed after the low-pressure mold clamping, the variation in the weight and density of the molded goods 1 is prevented.

Abstract: PROBLEM TO BE SOLVED: To keep a buckle mounting part, a floor or the like invisible and improve workability for fastening a belt buckle by setting the breadth of an open part for passing the belt buckle at a value smaller than the minimum breadth thereof, and forming an externally extended cut groove on the end of the open part. SOLUTION: An open part 10 is formed so as to extend along the lengthwise direction of a seat cushion 12 and the breadth W of the open part 10 is set at a value smaller than the minimum breadth W1 of a seat buckle 5. Also, cut grooves 15 externally extending beyond the open part 10 is formed on the ends 10a and 10b thereof along an open part extension direction and across an area from the upper part to the lower areas of the open part 10. When the belt buckle 5 is passed through the open part 10 from a position below the seat cushion 12, therefore, the open part 10 comes to have both sides 13a and 13b of a hard sponge 13 expanded toward the lateral breadthwise direction of the seat cushion 12 from the cut grooves 15.  In this case, as gathers 16 are formed on a skin material 14 within the open part 10, the skin material 14 also expands together, thereby smoothly expanding the open part 10.

Title: Ink jet recording head
Inventor: KODA HIROKAZU
IPC: B41J2/055
Filed: 1992-07-07
Abstract: PURPOSE:To make an ink jet recording head function effectively without inserting a tip of a piezoelectric element into an insertion opening leading to an ink pressure chamber of a nozzle by a method wherein an elastic material seal is made to abut against the insertion opening of the piezoelectric element leading to the ink pressure chamber, and an end part of the piezoelectric element is so constructed as to be covered by the seal material. CONSTITUTION:A nozzle 1 is composed of a nozzle orifice 2, an ink pressure chamber 3, an ink path part 4, a filter 5, and an insertion opening of a piezoelectric element 6 leading to the ink pressure chamber 3. An end part of the piezoelectric element is so constructed as to be covered by a seal material 7 by making the elastic seal material 7 abut against an inlet of the insertion opening of the piezoelectric element leading to the pressure chamber 3. A lower part of each piezoelectric element 6 is fixed to a base plate 8 with a fixing plate 9 herein, and each piezoelectric element is mutually connected to the fixing plate 9. Further, ink (a) is fed to a rear ink path part 4 to fill the pressure chamber 3, a front ink path part 4, and the nozzle orifice 2 via the filter 5. Therefore, though a dispersion in the insertion opening size of the piezoelectric element is large, transmission of displacement will not be hindered.
