Title: Manufacture of semiconductor device
Inventor: KAWAMATA TOSHIO
IPC: H01L21/306
Filed: 1979-03-30
Abstract: PURPOSE:To improve reliability and yield by a method wherein in the photoresist process the second etching pattern is provided to be larger than the first one, and in the electrode forming process the reverse relation is accepted. CONSTITUTION:By the first chemical etching process performed on an oxide film 2 on the surface of a semiconductor substrate 1, the part of which the dimension is the etching pattern dimension W1 is removed. Next, by the second chemical etching process, the part of which dimension is larger etching pattern dimension W2 than W1 is removed. The second process removes resist films and the residual the oxide film 2a. Next, the first chamical ethcing process for building a electrode etc. is performed to perforate the oxide film 2 so as to form the opening of which the dimension is the etching pattern dimension L1. Next, after the oxide film 2 is formed, the opening of which the dimension is the smaller etching pattern dimension L2 than L1 is formed by the second chemical etching process. By these processes, harmful effects due to side etching are eliminated.

Title: Preventing device for water-surface freezing
Inventor: SHIMA YUKIHIRO
IPC: G01F23/40
Filed: 1980-03-24
Abstract: PURPOSE:To obtain a water-surface freezing prevention device for a water gauge which does not require heating energy, by equipping the one-end condensation part of a heat transmitting tube to a float, and by arranging the other-end evaporation part at an underwater lower layer part. CONSTITUTION:On water surface 3 of well 2, float 1 is floated and the length of cord 6 is measured by water level measurement part 4 provided on lid 5 of well 2 to measure the position of float 1. One-end condensation part 7a of heat pipe 7, fixed to the reverse surface of this float 1 in contact, is arranged at underwater upper layer part 8, and the other-end evaporation part 7b is arranged in underwater lower layer 9. Since a working fluid such as ammonia and ''Flon   '' is sealed in the heat pipe, it absorbs evaporating heat H from underwater lower layer part 9 as the temperature of one-end condensation part 7a falls below that of the other-end evaporation part 7b and evaporation heat H is emitted to underwater upper layer part 8 at condensation part 7a, so that even if well 2 is held at the freezing temperature, the water surface can be prevented from freezing.

Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent a wrong dialing caused in an artificial process such as 'taking a memo' by displaying visually a telephone number sent by digital data and storing the data to a storage means. SOLUTION: While a telephone number is displayed on a display section 11, when a 'memory' key 12 is depressed to store a telephone number being displayed to a memory. The stored telephone number is read and displayed by depressing a 'call' key 13. In this state, when a 'start' key 14 is depressed, the telephone number being displayed is dialed. A radio base station 2 connects a radio telephone set 1 and an operator side device 3. In the case of guiding a telephone number for the user, the operator obtains an object telephone number from a database 32 through the operation, of an operator operation section 31. The operator side equipment 3 sends the telephone number required for guide to a radio telephone set 1 via a radio station 2 in terms of a voice signal and digital data.

Title: Bored parts feeder
Inventor: AOYAMA YOSHITAKA
IPC: B65G47/92
Filed: 1988-02-19
Abstract: PURPOSE:To hold a part reliably, in a short and bored parts feeder, by constructing the parts feeder with a supply rod and inner and outer shafts such that a part is carried while being attracted to the inner shaft and separated by means of the outer shaft when the inner shaft retreats. CONSTITUTION:A supply rod 10 is advanced by means of a cylinder 22 and a part 14 placed on an openable cover 35 is attracted to a magnet. When the supply rod 10 is advanced further under this state, the part 14 pushes open the cover 35 and advances to a predetermined position. At this time, the pushing section 18 of the outer shaft 11 advances together while contacting with the upper face of the part 14. Then a cylinder 31 is contracted to return a regulating pin 38 through a stopper chip 33. Consequently, only the inner shaft 12 retreats and the pushing section 18 of the outer shaft 11 pushes the part 14 and separates the part 14 from the magnet. By such arrangement, the part can be held reliably.

Title: Optical pickup driving device
Inventor: OONUKI HIDEO
IPC: G11B7/09
Filed: 1980-03-28
Abstract: PURPOSE:To enable the device with high reliability, by making the pickup main body toward three coordinate axes movable independently. CONSTITUTION:When the permanent magnet 7 is magnetized, magnetic lines go toward the arrow C at the part located with the voice coil 4, and the magnetic lines go toward the arrow B at the part located with the coil 12. Thus, when electric current flows to the voice coil 4, the force toward z is caused between the optical pickup main body 2 and the magnetic circuit 13. The optical pickup main body 2 is lighter than the weight of the magnetic circuit 13 and connected to the magnetic circuit 13 via the support 5 rigid toward x and y and soft toward z. Further, the circuit 13 is connected to the frame 11 via the support 10 soft toward x and y rigid toward z. Thus, most of force toward z caused between the optical pickup main  body 2 and the magnetic circuit 13 is used to displace the optical pickup main body 2 toward z and the magnetic circuit 13 is not almost moved.

Title: Shuttle mechanism of printer
Inventor: WATANABE TOSHIHIKO
IPC: B41J2/245
Filed: 1984-02-29
Abstract: PURPOSE:To arrange so that unprinted lines may be processed effectively by providng a passage sensor means at the right end or left end of a printing zone in a shuttle base and varying a direction changeover timing of the shuttle base in accordance with the number of unprinted lines in printing data. CONSTITUTION:Positions a, b represent the right and left ends of a printing width under the control of a printing device 4. That is, the positions fall on the right and left ends 15, 16 of a shuttle base 5. If the passage of the shuttle base 5 through the position (a) or (b) is detected by an optical sensor 8, an instruction for direction changeover is issued to a motor 6 from a control unit 10, resulting in the changeover of the shuttle 6. If the following line is not printed, the timing for the instruction for direction changeover is sequentially delayed to C, E and G according to the number of unprinted lines. Consequently, if each speed such as A-B, C-D, E-F and G-H, i.e. the time required at such speed is the same, time required for direction changeover can be sequentially changed by varying an instruction point for direction changeover to C, E and G.

Title: Semiconductor optical element, light-emitting diode and manufacture thereof
Inventor: UNNO TSUNEHIRO
IPC: H01L21/208
Filed: 1992-02-26
Abstract: PURPOSE:To prevent the lowering of brightness, the dispersion of brightness and a thyristor phenomenon by using a dopant difficult to diffuse even when a P-N interface is grown at a high temperature. CONSTITUTION:Mg is employed as the P-type dopant of a P-type epitaxial layer constituting an AlGaAs group red light-emitting diode having double hetero-structure. A changeover temperature at the time of P-N interface growth from a P-type AlGaAs active layer to an N-type AlGaAs window layer by liquid-phase epitaxial growth is elevated to 840-950 deg.C. In luminous brightness characteristics, difference is hardly formed in Zn doping and Mg doping when a P-N changeover temperature is lower than 840 deg.C, but Mg doping is larger than Zn doping when the changeover temperature exceeds 840 deg.C. When the temperature is elavated, the dispersion of luminous brightness in a surface is increased, but the effect of the temperature is not so larger as Zn doping at the time of Mg.
