Abstract: PURPOSE:To obtain a surface incidence type element having small capacitance characteristics, by stacking in order a first semiconductor layer with a band gap E1 and a second semiconductor layer with a band gap E2 (E2>E1) which have the same conductivity type, in a specified region of a semiinsulative semiconductor substrate, and forming the specified region of the substrate in such a manner as to exhibit the inverse conductivity type. CONSTITUTION:In a specified region 7 of a semiinsulative InP substrate 1, Be<+> is ion-implanted, and an n<->-InGaAs light absorbing layer 3 and an n-InP window layer 5 are continuously formed by vapor growth method. During this period, Be<+> ion is thermally diffused also in the n<->-InGaAs layer 3, a p<+>-InGaAs region 4 is formed, and a p-n junction is positioned in the InGaAs. By etching, a part of the light absorbing layer 3 and the window layer 5 is eliminated, and a part of the surface of the InP substrate 1 containing the p<+> region 2 is exposed. The upper region of the p<+>-InGaAs region 4 left by the above etching is turned into the light receiving region of the element. On the InP substrate 1 whose surface is exposed, a p-side electrode 6 is formed so as to bridge the p<+>-InP region 2, and an n-side electrode 8 is formed in a region which is not positioned on the light receiving region of the surface of the n-InP window layer.

Title: Formation of terminal part of indirectly heated cathode
Inventor: ITO SHIGEO
IPC: H01J9/08
Filed: 1990-03-22
Abstract: PURPOSE:To form a terminal part of an indirectly heated cathode easily by holding an end part of an indirectly heated cathode, applying a tension, cutting a heater part, loosening a metal wire, separating it, and pressing one part to break an insulation layer and expose a heater line. CONSTITUTION:An inner end part and an outer end part at one end part of an indirectly heated cathode A are held by a first chuck 11, a third chuck 13, and a fourth chuck 14 respectively, and a tension is applied, then a heater line 1 is cut first. A metal wire 3a of a cathode base body 3 is longer than the heater line 1, so it is not cut but wound and loosened, and in loosening the metal wire 3a, electron emitting material 4 is peeled. By drawing the metal wire 3a or rotating the metal wire 3a, the metal wire 3a can be separated from a heater part, and by holding the exposed heater part, an insulation layer 2 can be broken to expose the heater line 1, so a terminal part of the indirectly heated cathode A can be formed. Thus, the heater line can easily be exposed to be formed into a terminal part directly.

Title: Transistor circuit
Inventor: MURAYAMA AKIHIRO
IPC: H03K3/2897
Filed: 1986-03-31
Abstract: PURPOSE:To set the hysteresis voltage over a wide range and to decrease the temperature dependancy by connecting a resistor between emitter of both transistors (TR) and decreasing the current of the emitter current source of the TR turned off. CONSTITUTION:When an input voltage Vi is large enough to cut off a TR Q2, an output current I2 of a current mirror circuit 15 is expressed as I2=IR=nIR =0 and the output current IL of the current mirror circuit 14 is expressed as IL=I1. A TR Q4 gives a current nLIL to a resistor R2 and a TR Q12 is cut off. Thus, no current flows to a resistor RE. When the input voltage Vi is decreased, an output current I2 starts flowing to the TR Q2 through the resistor RE, but the TR Q9 is saturated while I2<I1, and the output current IR flows when I2<I1, then the current nRIR flows to the resistor Rl to decrease a current Iref1 thereby inverting the state.

Title: Rotary encoder
Inventor: KURODA MASASHI
IPC: G01D5/36
Filed: 1991-01-18
Abstract: PURPOSE:To reduce the thickness of a rotary encoder in the direction of its rotating shaft so as to reduce the size and thickness of the encoder by putting a cylinder provided with slits formed at regular intervals in its cylindrical section on the outer periphery of the cylinder between a bottom plate and wiring board and arranging light emitting elements, fixed slit plates, and photodetectors in the radial direction from the rotating shaft of the encoder on the wiring board. CONSTITUTION:Numerous slits 12A are formed in a cylindrical section on the outer periphery of a rotary slit cylinder 12 so that the piercing direction of a hole can be directed to the center of the cylinder 12. When a wiring board 16 fitted with light emitting elements 13A and 13B, fixed slit plates 14A and 14B, and photodetectors 15A and 15B arranged in two lines in the radial direction from a rotating shaft 11 is put on a bottom plate 17 as a lid after the cylinder 12 is put in a recessed section formed on the plate 17, the slits 12A are positioned so that they can intercept the optical paths from the elements 13A and 13B to the elements 15A and 15B. Since the slit plates 14A and 14B are positioned so that the light can intermittently pass through the plates 14A and 14B with a 90-degree phase difference against the slits 12A, the light passed trough the slit plates 14A and 14B is received by means of the elements 15A and 15B as two intermittent rays of light having a 90-degree phase difference and used for detecting the rotating direction. Since the three kinds of elements are arranged in the radial direction from the rotating shaft, the thickness of this encoder can be reduced in the direction of the rotating shaft.

IPC: F01D5/18
Filed: 1980-06-04
Abstract: PURPOSE: To efficiently cool the moving vane of a turbine which is provided with a coolant passage under the surface, by separating a liquid coolant from vapor produced in the passage and by causing the vapor to go out through small holes opened in the surface of the vane.  
     CONSTITUTION: To cool the moving vane of a turbine, a coolant 11 flows from a reservoir 12 at the mounted bottom of the vane and overflows a weir 13 and enters into a main coolant passage 2. The coolant flows due to a thermosiphon effect as shown by an arrow 14 and moves from a coolant passage 3 at the tip of the vane to another coolant passage 4 under the surface of the vane. The coolant 11 enters into a reservoir 5 after cooling the vane. The coolant 11 then flows into the main passage 2 again through a goove 6 and repeats the above-mentioned process of flow. In the process, vapor produced in the cooling coolant passage 4 is separated from the liquid coolant in the reservoir 5 and then flows into a vapor passage 7 through a weir 8 and enters into a main high-temperature gas flow through numerous small holes 9 in the surface of the vane to keep the heat of high-temperature gas from coming into the moving vane.

Abstract: PROBLEM TO BE SOLVED: To reduce the area for arranging conductors by setting the length of a transmission line substantially equal to a quarter of wavelength on the transmission line at an operating frequency and setting the cross-sectional area of the transmission line in correspondence with the current distribution thereby preventing damage of the conductors due to eddy current. SOLUTION: Length of the line conductors 41 in a transmission line is set substantially equal to a quarter of wavelength on the transmission line at the frequency of an AC voltage being applied to these conductors. Cross-sectional area of the line conductor 41 is set in correspondence with the current distribution thereof. Since the current distribution decreases gradually from the input side end 41b toward the output side end 41a, cross-sectional area of the line conductor 41 is decreased gradually from the input side end 41b toward the output side end 41a. According to the arrangement, the conductors are protected against damage due to eddy current while reducing the area for arranging conductors and the size is reduced while sustaining high boost ratio and high conversion efficiency.
