Title: Transistor amplifier circuit
Inventor: HAMAGUCHI KOZO
IPC: H03F3/34
Filed: 1988-03-18
Abstract: PURPOSE:To respectively independently set the direct current operating point and the voltage gain of an output signal by connecting constant current circuits having the same current value respectively to the emitter and the collector of a transistor having the collector connected to an output terminal. CONSTITUTION:The conductive path of the transistor(Tr) 6 is disposed in parallel to a conductive path between the base and the emitter of Tr 5 and a direct current voltage source 9 is connected to the common base of both the Trs. Thereby, the collector current of the Tr 6 goes to the reference current of the constant current circuit constituted of the Trs 10, 11 and resistances 12, 13. Consequently, the current of I0 is passed to the collector of the Tr, and the current of I0 is passed as the collector current of the Tr 11. When the voltage gain of a Tr amplifying circuit and the direct current level of an output terminal are set, the collector current and the resistance 16 of the Tr 2 are determined, thereby, the voltage gain G2 is initially decided to a desired value. Then, when the voltage and the resistance 15 of a direct current level setting terminal 18 having no relation to the G2 and the voltage of a reference voltage terminal 20 are set, the direct current level of the output terminal 19 is decided.

Abstract: PURPOSE:To simplify both control of an etching and the process of manufacture of the titled semiconductor device by a method wherein the difference in refractive index in horizontal direction is provided on a P-N junction face, and a high density impurity diffusion layer is provided around an active layer. CONSTITUTION:The specified region on a double-hetero epitaxial substrate is removed, and a concavity 16 is provided on the confinement region forming part of a clad layer 14. Then, a part of a CVDSiO film 15 is newly removed, a window 17 of stripe pattern is provided, and a high density Zn diffusion is performed. Said diffusion is to be performed in such a manner that the Zn diffusion depth from the window 17 will be limited within the active layer 13 or a little shallower so that the Zn diffused from a concavity 16 will be entered into an N type clad layer 12. As a result, the refractive index of the high density Zn diffusion layer on a P<+> region 18a is reduced, the region located below the window 17 is surrounded by a low-refractive-index layer, and there exists a refractive difference in the horizontal direction of the P-N junction surface too, thereby enabling to stabilize the lateral mode of the laser oscillation. Also, the injected current mainly runs directly below a P<+> region 18b, and turned to the laser having a threshold current value. Then, an SiO2 film 19 is formed by removing an SiO2 film 15, the SiO2 film on a P<+> region 18b is removed, and an electrode is vapor-deposited. An Au/Zn alloy layer 20 is formed on the Zn diffusion layer 18b, and an Au/Sn alloy layer 21 is formed on the back side of the substrate 11.

Filed: 1993-03-24
Abstract: PURPOSE:To shorten an instruction length in a central processing unit by providing a storage device setting a register executing an operation and an instruction set executing an operation for the register which is set. CONSTITUTION:The central arithmetic processing device is provided with the storage device setting the register executing the operation shown in a diagram (a), and the instruction set executing the operation for the set register, which is shown in a diagram (b). An OP1 and OP2 setting instruction sets the register which executes the instruction and executes the operation before the instruction shown in the diagram (b) is executed. The arbitrary registers are set for respective OP setting numbers. Since the byte width of the instruction can be reduced, the number of the instructions which are once read into the central arithmetic processing device is increased. Thus, processing speed can be improved. Since the byte width of the instruction is not directly increased by the number of the registers, the number of the registers in the central processing unit can be increased. Since the much more instructions can be executed by the cache memory of a decided size, the hit ratio of the cache memory improves.

IPC: H01G9/20
Filed: 1987-03-18
Abstract: PURPOSE:To get higher photoelectric efficiency and a longer lifetime of the battery in the caption by coating a light receiving surface with a carbon membrane including an electrically conductive diamond membrane. CONSTITUTION:A carbon membrane 24 including a diamond-structure is formed on the light receiving-surface 21A of the n-Si substrate 21 of a light receiving- part 20 to cut off direct contact between the substrate 21 at the light receiving- surface 21A and ions, etc., in electrolyte 13. The membrane 24 is formed as its thickness is 100-50000Angstrom . The excessive electrons l<-> of the substrate 21 are optically excited by radiating light 1 from a light receiving-window 14 to the light receiving part 20. The membrane 24 cuts off contact between such as oxygen or hydrogen ions, etc., in electrolyte 13 and the light receiving-surface 21A but allows electrons l<-> to pass through because it is doped in n-type. The light receiving surface 21A oxidized electrolyte 13 based on a difference of chemical potencial between the substrate 21 and electrolyte 13, increases hydrogen ions in electrolyte 13 and also generates an optical electromotive force. Energy of light 1 is photoelectrically converted and consumed by a resistor 19.

Abstract: PURPOSE:To make corrective polishing for a microscopic part stably and accurately performable, by forming the tip of a polishing tool, pressing the back of a taper with an abradant to be fed in the specified direction, with a spherical body of a steel ball or the like tightly attached. CONSTITUTION:A lap tape 39 is guided by a guide roller 58, entering an interspace between a lower groove part 38a of a nose 38 and a sleeve 74, and it passes through the exposed spherical tip part 38b as being bent, then it reenters the interspace between the upper groove 38a and the sleeve 74, accurately guided out of a guide roller 59, pressing the nose 38 to a polished surface, whereby polishing at an accurate working position comes possible. A tip form of the nose 38 is required to be of highly accurate sphericity, therefore spherical polishing for the tip part 38b is hard to be carried out at the integral type nose 38, so that a steel ball 106 for a bearing ball or the like on the market is tightly attached to a tip of a nose body 38c by a bonding agent or the like, and if each tape guide groove 106a is formed or both upper and lower surfaces, the highly accurate sphericity is obtained. Thus, fine partial corrective polishing is performable in a highly accurate manner.
