Title: Optical semiconductor module
Inventor: SATO KAZUYOSHI
IPC: G02B6/42
Filed: 1989-05-31
Abstract: PURPOSE:To fix an optical fiber terminal member to a holding member without using an adhesive and to prevent a useable range of an optical semiconductor module from being influenced by a hardening temperature of the adhesive by welding the holding member and the optical fiber terminal member. CONSTITUTION:A focusing rod lens 5 is held by a holding member 6. Subsequently, an optical fiber terminal member 4 for holding an optical fiber housing 3 being a housing of an optical fiber 2 is put into the holding member 6, and screwed by a screw coupling part 8 so that there is no clearance between both of them. Next, joining parts 9A, 9B of the holding member 6 and the optical fiber terminal member 4 are brought to spot welding by a high output laser, etc. Thereafter, a light emission diode element 1 is adjusted to an optimum position in which an emitted light is made incident on the optical fiber most efficiently. Also, joining parts 9C, 9D of a light emission diode element holding member 12 and the holding member 6 are brought to spot welding in the same way. In such a way, since no adhesive is used, it does not occur that a useable temperature range of a semiconductor module is limited by a hardening temperature of the adhesive.

Abstract: PURPOSE:To perform clear judgment by detecting the vapor of object fuel as an ionizing current. CONSTITUTION:A gas pickup pipe 50 is inserted into liquid 40 such as gasoline, kerosine gas oil and the like. Air is sent into the pipe 50 from a ventilating device 30, and vapor from the liquid 40 pipe 50 from a ventilating device 30, and vapor from the liquid 40 is recovered. The change in ionizing current in a sensor 10 due to the vapor is detected, and the respective fuels are identified. In the sensor 10, two electrodes are made to face an intermediate electrode 11. One electrode is made to be an open electrode 13 wherein the vapors of the gasoline and the kerosine or the gas oil can intrude. The other is made to be the tightly sealed electrode 14 wherein the vapor does not intrude. Both electrodes 13 and 14 are positioned in series for a power source 20. The change in ionizing current due to the vapor is measured as the voltage of the electrode 11. Thus the gasoline and the kerosine or the gas oil can be clearly discriminated.

Title: Surface treatment apparatus
Inventor: IGAWA EIJI
IPC: H01L21/302
Filed: 1985-06-25
Abstract: PURPOSE:To remove a damaged layer of an Si substrate and eliminate remaining reactive gas molecules and atoms from the surface of the Si substrate by etching the damaged layer at the low temperature about 400 deg.C and with good controllability. CONSTITUTION:A treatment gas is introduced into an evacuated vacuum apparatus while being evacuated. High power ultraviolet rays are applied to an Si substrate placed on a target and a damaged layer is etched. After the etching is completed, introduction of the treatment gas is discontinued and, while being evacuated to the high vacuum rate again, UV application only is performed to elevate the substrate temperature. In other words, halogen molecules and atoms adsorbed by the Si surface layer are dissociated under the elevated temperature and decreased pressure while the lights are being applied so as to make adsorbed atoms or molecules not to remain on the Si surface layer at all.

Abstract: PURPOSE:To make an automatic two-band channel selection with two switches by placing a storage means stored with a selected band in such a state that the 1st band is selected when a switch for selecting a specific station in the 1st band is operated. CONSTITUTION:The output (a) of a T-FF29 is inverted every time a switch 25 is pressed, so transistors (TR) 22 and 23 are turned on alternately to supply a current to an MW (medium wave range) reception part 16 and an UKW (ultra high frequency range) reception part 17 alternately, so that one of two bands is selected with this switch 25. The output (b) of a T-FF30 is inverted every time a switch 26 is pressed, and a processor 11 controls a local oscillation part 18 when the output (b) is 1. At this time, the T-FF29 also has a set input, so it enters a state wherein the UKW band is selected forcibly; and the UKW reception part 17 is in operation and the local oscillation frequency is varied until a detecting circuit 19 detects a pilot signal for automatic channel selection.

Title: Calling system for terminal unit
Inventor: NAKAZAWA MASANORI
IPC: H04Q9/00
Filed: 1979-10-30
Abstract: PURPOSE:To simplify the call without losing the reliability of collection of data, by securing such constitution in that each terminal transmits the data successively in response to the common call signal supplied from the center unit. CONSTITUTION:The central unit 1, when starting the collection of data, transmits the call signal to the line 2. The meter sensors 3A, 3B...3N comprise the call detecting circuit connected to the line 2, the timer circuit and the encoder which is connected to the meters 4A, 4B...4N and transmits the data to the line 2 respectively. For the timer circuits incorporated into the sensors 3A, 3B...3N, the set time of the timer differs with every sensor which is started by the call signal sent from the unit 1. The encoder is started after the set time of the timer, and thus the data are transmitted successively to the unit 1 from the sensors 3A, 3B...3N each.

Title: Conducting contact terminal
Inventor: HITOMI YASUYUKI
IPC: G01R1/073
Filed: 1994-05-17
Abstract: PURPOSE:To provide a conducting contact terminal which is prevented from being broken, and never shifted from the pattern of a liquid crystal cell. CONSTITUTION:A conducting contact terminal 1 has a plurality of contacts 2 arranged at equal intervals and nipped by a P glass 4 and holder 5 which are insulating members so that the top ends are protruded in a prescribed quantity, and a silicon rubber 6 which is an elastic body is adhered and fixed to the vicinity of the top end of the holder 5. The contact 2 is adhered and fixed to the silicon rubber 6 with the top end being slightly protruded from the silicon rubber 56. Since the contact is supported by the silicon rubber in this conducting contact terminal, a stress never collectively act on the position where the contact is arranged, and a damage such as breakage of the contact can be avoided. Since the contact top end protruded from the silicon rubber is slight, the contact is never shifted from the pattern of a liquid crystal cell when pressed onto the pattern.
