Title: Electrode structure of semiconductor device
Inventor: MITSUI KOTARO
IPC: H01L31/04
Filed: 1989-03-28
Abstract: PURPOSE:To stably make a wiring high enough in bonding strength by a method wherein an Au layer thick enough to prevent Ag from deteriorating is provided onto Ag. CONSTITUTION:An extremely thin Au layer 5 is provided onto a P-electrode 3 and an N-electrode 4 of an Si solar cell 11, where the thickness of the Au layer 5 is so set as to be just enough to prevent the surface of Ag from deteriorating. The Au layer 5 is able to prevent the surface of Ag from deteriorating keeping it from being oxidized or sulfurated due to exposure to the air, and Au itself is very chemically stable and its surface hardly deteriorates. Therefore, the clean surface of Au is brought into contact with a connector at the welding of the connector, so that the connection of a connector high enough in bonding strength and excellent in reproducibility can be realized. By this setup, a current blocking factor caused by oxide or sulfide can be eliminated, so that a stable welding can be made.

Title: Enhancement of luminescent emission
Inventor: MURAO YASUO
IPC: G01N33/535
Filed: 1995-04-03
Abstract: PURPOSE: To enable an immunoassay of high sensitivity by enhancing the light emission reaction of cypridina luciferase in the presence of calcium ion and using the cypridina luciferase as a marker for immunoassay reagents. CONSTITUTION: Cypridina luciferin as a light emission substrate is dissolved in 10mM sodium citrate buffer.140mM sodium chloride solution (pH4.5) and calcium ion such as calcium chloride is added to the solution in an amount of 5μM-5 mM. Then, A 100mM tris hydrochloride buffer solution containing cypridina luciferase (pH7.2) is added to the luciferin solution and, after 10 seconds, the 10-second emission is measured with a luminometer. This measurement process is carried out in the presence of calcium ion to increase both of the emission value and the S/N ratio to increase the measurement sensitivity more than double in comparison with the luciferin measurement without calcium ion.

Title: Semiconductor light emitting element
Inventor: WATANABE AKIRA
IPC: H01L33/30
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the light emitting efficiency, without reducing the product life by doping of specified amt. of Si or more into a compd. semiconductor layer formed beneath multilayer films including a light emitting layer. SOLUTION: A compd. semiconductor layer 3 formed beneath multilayer films 4-6, including a light emitting layer is set for a Si concn. of 1×10<18> or more, resulting in the increase of the electron density in this layer 3. Thus, the electrons implanted in the light emitting layer also increase to provide a high-emission efficiency light emitting element. The multilayer films 4-6 themselves, including the light emitting layer are not much doped with Si but the lower layer of these films is much doped with Si. Hence the crystal defect is never induced in these films 4-6 themselves, including the light emitting layer and this never reduces the life of the light emitting element. Thus it is possible to improve the light emission efficiency, without reducing the product life, and it is available for high speed printers at printing speeds of 18 sheets/min or more.

Title: Af control method for optical head
Inventor: ENDO KIYONOBU
IPC: G11B7/09
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the generation of a reproduced light deterioration by giving an offset through an autofocusing AF control loop, and controlling the size of a cast spot on a recording medium, to be larger than that at the time of a focusing, when the recording medium stands still. CONSTITUTION:An output from an amplifier 15 is processed by a phase compensation circuit 17 and an actuator driver circuit 18, and impressed to an actuator 6. When an AF draw-in operation is finished, an offset instructing signal is impressed to a servo circuit 8 from a system controller 4, and a switch circuit 15 comes conductive to V2, and the spot is expanded. Afterward, an insulation for selecting a track from the system controller 4 is sent to a head feeding driver. When the track selection is finished, the spot stands still in a state that the spot is expanded, and when information is recorded or reproduced, the offset is canceled. (i.e., the switch circuit 16 is energized to V1 side.) Thus, the problem of the reproduced light deterioration, after the AF drawing and in the standing still state of the light spot in a stand-by state till the recording and the reproducing, can be solved.

Filed: 1994-04-18
Abstract: PURPOSE:To prevent drying from occurring and enable rapid recovering operation by working a drying apparatus by closing a closing means for a storing structure and working an ink head recovering apparatus by releasing the closing means. CONSTITUTION:A protector hood 1c makes the length of a projection shorter than the length of an ink ejecting part 2a in an ink head cartridge 2. When a scanner head cartridge 1 is stored, it is at a position being apart from an elastic member 5 and as a sensor lens 1a and an illuminator 1b are not brought into contact with any article, there exist no possibility of contaminating a light path. As the sensor lens 1a and the illuminator 1b are insulated from waste and dust by closing a lid 3, the scanner head cartridge 1 or an ink head cartridge 2 being not used can be stored under a good condition for a long time. Clogging and sticking of the ink in the ink ejecting part caused by drying of the ink head cartridge 2 while it is not used can be prevented from occurring.

Title: Thyristor type exciter for generator
Inventor: SUZUKI TETSUO
IPC: H02P9/10
Filed: 1982-05-11
Abstract: PURPOSE:To readily discover the cause and the position of a trouble in a generator by providing a device for compensating a field current to supply a trouble current necessary for the operation of a protecting relay of a main circuit. CONSTITUTION:When 3-phase shortcircuit trouble occurs in a generator bus 15 so that a power source voltage drops, a protecting relay 3 for an exciter is energized. Thus, a contact 9 is closed, and the preset current flows via a resistor 10 in a field circuit. On the other hand, since the generator 1 continues rotation by the flywheel effect, it generates an output, and the relay 2 is operated by the generated current. In this manner, since the field current is compensated even when the power source voltage of the exciter decreases or is lost, the cause of the trouble can be readily discovered, and a repairing work can be shortened.

Abstract: PURPOSE:To provide an excellent riding sensation by calculating a riding ratio from the internal pressure of an air spring during the stop of a vehicle, and fetching from a data base such data for control optimum to the riding ratio from a relation between a preset riding ratio and data for control so as to perform multivariable digital control. CONSTITUTION:It is decided by means of a speed signal from a speedometer 30 whether a vehicle is under a stop. When the rolling stock is under a stop, decision right before departure or starting from the start of low speed running is effected. This method measures a timing at which the number of passengers during a time between closing of the entrance door of a rolling stock and arrival to a next station is approximately decided. A riding index beta is determined from the internal pressure of an air spring, and matrixes Adn, Bdn, and Cdn for control optimum to a current riding index are read from a data base. Computation based on given control theory is executed by using each sensor value for each control period. A control input u is outputted to a proportional flow rate control valve 20 for driving a fluid actuator so as to suppress vibration.
