Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To accurately perform antenna direction adjustment according to the change of a musical interval of an audio sound generated from a sound emitting part, even under any temperature condition. SOLUTION: A voltage value measured in a temperature measuring part 15 and a voltage value that corresponds to a receive input level outputted from an amplifying part 9 through a detecting part 8 are converted into digital data by A/D converting parts 16 and 14 respectively and inputted to a ROM 17. The ROM 17 calculates an accurate receiving level, based on the digital data and further calculates a digitally represented voltage value by considering even a temperature characteristic of a low frequency oscillating part 10 which is known in advance. The digitally represented voltage value is converted into an analog voltage in a D/A converting part 20, and the part 10 outputs a frequency corresponding to the analog voltage to a sound emitting part 13.  The part 13 generates an audio sound of a musical interval, in accordance with a frequency that is not changed by the temperature from the part 10.

Title: Engine-driven generator
Inventor: SHIMIZU MOTOHISA
IPC: H02P9/04
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To enable an engine-driven generator to always respond to load fluctuations with surplus power. SOLUTION: The output current of a generator 1 driven by means of an engine 2 is rectified by a converter 3 composed of a thyristor bridge and an inverter 4 connects the direct current outputted from the converter 3 to a load 5 after converting the direct current into an alternating current having the commercial frequency. A thyristor drive circuit 9 controls the conduction of a thyristor, so as to maintain the input-side voltage of the inverter 4 at a fixed value. A fuel quantity control section 10 detects the conducting angle of the thyristor and controls the number of revolutions of the engine 2 so as to make the conducting angle maintain at a target conducting angle.  When the target conducting angle is set in a prearranged range lower than the maximum conducting angle, a stable voltage can be obtained from the generator, and the generator can respond quickly to load fluctuations, because the generator is always in such a state that the generator has surplus power.

Title: Key pad and manufacture thereof
Inventor: HISADA TAIZO
IPC: H01H13/14
Filed: 1993-04-30
Abstract: PURPOSE:To permit direct adhesion of a resin layer without using any adhesive by forming a character-printed layer which contains silicone rubber on the upper side of the key top of a key pad main body made of silicone rubber, and drying and hardening a layer of liquid transparent resin. CONSTITUTION:As a key pad main body 1 made from silicone rubber and comprising a character-printed layer 2 formed on the upper side of a key top 1b is conveyed using a belt conveyor or the like, the surface layer on the upper side of the main body is subjected to a corona discharge treatment. Next, a transparent resin such as a liquid epoxy resin is either dropped onto the layer 2 or screen-printed on the layer 2 and then dried and hardened. Because of the corona discharge, molecular bonds on the upper side of the key top 1b are destroyed and free radicals in the molecular chains rapidly react and bond with the transparent resin to form a layer 3 of transparent resin over the layer 2. Thus silicone rubber and resin, which were considered to be hard to adhere to each other, can be made to adhere directly to each other and the need for adhesives or primer coating is eliminated, whereby the operations required can be prevented from becoming complex.

Title: Cathode sputtering apparatus for detecting target drill hole
Inventor: BOTSUGUDAN ZEGA
IPC: H01L21/285
Filed: 1981-08-08
Abstract: The sputtering cathode (10) forming part of the apparatus of the invention essentially comprises a target (20) made of a material to be sputtered, arranged in front of an intermediate support (15) so as to define a first gas tight chamber (30) of narrow thickness therebetween, intended to be provided with an atmosphere of a gas (37) presenting a high thermal conductivity (under a pressure substantially higher than that prevailing inside the vacuum chamber of the apparatus). The intermediate support (15) in turn forms part of the wall of a second tight chamber adjoining said first tight chamber, which is intended to be circulated with a liquid coolant therewithin. The above arrangement enables the sputtering target (20) to be consumed up to its piercing without causing any damage for the apparatus and/or the substrates being coated, since this piercing will result in a simple gas irruption inside the vacuum chamber (3), which may be at once detected for immediately controlling the automatic shut-off of the sputtering operation. The above arrangement further enables sufficient target cooling throughout the sputtering.

IPC: F23D11/44
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To enable starting of a vaporizer, lowering of a running cost for temperature adjustment and starting of the vaporizer in a short time by providing a burner for receiving heat which is disposed independently of a main burner for heating the heat receiving part of the vaporizer. SOLUTION: A burner head 30 is divided into an area (an auxiliary burner head 60) adjacent to fins 46 and 56 of two vaporizers 40 and 50 and other areas (a main burner head 62). The degree of combustion can be adjusted at the main burner head 62 by properly adjusting the degree of combustion at an auxiliary burner head 60. In this manner, the shortage of heat at a main vaporizer 40 is compensated for by increasing the degree of combustion at the auxiliary burner head 60. This enables lowering of a running cost as compared with the case of compensating for the shortage of heat with a heater while shortening the time up to the start of combustion at the main burner head 62.

Filed: 1979-09-28
Abstract: PURPOSE:To improve reliability and reduce cost by a construction wherein a P-N jucntion and another one as a protective ring are formed with high reproducibility through a single process of continuous epitaxial growth and that of diffusion. CONSTITUTION:A circular hill 11' is formed by etching away the surface (100) of an N<+> type InP layer 11, and the hill is covered with an N type In0.79Ga0.21 As0.47P0.53 layer 12 and an N type InP layer 13 epitaxially. The layer 13 is further covered with an SiO2 film, while a Cd diffusion layer is provided in a region 13' above the hill 11' to form a P-N junction 16. An SiO2 layer 14' is again added, and a circular opening is made in the layer, then a P type ohmic electrode 17 is formed in a ring shape. Simultaneously, an N type ohmic electrode 18 is formed on the base of the substrate 11. Since the P-N junction is located near the substrate, a reverse bias, when it is applied, uniformly yields with the P-N junction above the substrate 11 without the influence of a peripheral junction. Such a construction as this makes it possible to improve the reliability of a light detector and reduce cost due to simple processing.
