Title: Infrared detector
Inventor: AIHARA SATOSHI
IPC: G01J5/02
Filed: 1994-02-09
Abstract: PURPOSE:To reduce the pad stress at the peripheral part of a bump array due to cooling and to achieve resistance against a long repeated operation by performing die bonding with silicone adhesive which does not lose rubber-like elasticity even at a low temperature. CONSTITUTION:A hybrid infrared ray detection element where an infrared ray detection part 5 of InSb and an electric charge transfer part 6 formed by silicon are connected by a number of indium bumps 7 is adhered by an adhesive layer 200 based on silicone adhesive TSE392 and is left as it is for curing. The investigation of cooling/heating heat cycle durability of an infrared ray detector indicates that the connection of the indium bumps 7 is partially released due to several heat cycles but the release completely disappear even by 50 heat cycles since the mismatching of the inflation coefficient of alumina ceramic constituting a chip carrier and that of silicon can be absorbed by the deformation of the silicone adhesive 200 with elasticity even at a low temperature.

Abstract: PURPOSE: To reduce the cost of manufacture and facilitate the maintenance by forming a coating and drying apparatus and heating furnace as a collective unit and setting a bulb heating temperature to be below the strain point of the bulb.  
     CONSTITUTION: When a bulb A is supplied from a point (a) to a bulb holder 3, it is transferred to a bulb washing section 4 to be washed there and then transferred to a drying section 5 with the movement of a bulb transfer conveyor 2. Then, as the bulb A reaches a fluorescent agent suspension coating section 6 a predetermined quantity of fluorescent agent suspension is sprayed onto and coated on the inner surface of the bulb A. As the bulb A is subsequently brought to a solvent drying section 7, the solvent in the coating film is dried. Thereafter, the bulb A is heated in a heating furnace 8, whereby a desired fluorescent film is formed on the inner wall of the bulb A.

Title: Measuring apparatus of bioimpedance
Inventor: TAKEMAE TADASHI
IPC: A61B5/04
Filed: 1988-01-25
Abstract: PURPOSE:To limit the distribution of a current to a measuring part and thereby to measure an impedance accurately, by a method wherein an eddy current generated by a magnetic field is superposed on an alternating current which is made to flow by a pole-dipole array. CONSTITUTION:The output of a signal source 1 is connected to an insulating transformer 2 to form an alternating constant current source 3, and an output E0 thereof is impressed from a pair of current electrodes 4 and 5 on an organism, e.g. a finger 6. On the other side, electromagnets 7 and 8 are disposed between the electrodes 4 and 5, holding the finger 6 between them, and the two magnets 7 and 8 are excited by an alternating current being synchronized with an alternating constant current. Thereby an eddy current is impressed from the electromagnets on a part through which the constant current flows. The distribution of current is different between a side A and a side B located on the opposite sides of these electrodes 7 and 8, and herein a construction is made so that the constant current and the eddy current have the same phase and intensify each other on the side A while they are shifted in the phase by 180 deg. from each other on the side B. The limitation of the current distribution and the detection of a potential difference are conducted by a couple of electrodes 10 and 11 stuck on the side A and the side B respectively, through the intermediary of amplifiers 12 and 13.

Title: Transistor inverter
Inventor: AOIKE MINAKI
IPC: H02M7/5383
Filed: 1981-02-04
Abstract: PURPOSE:To alleviate the power loss of a transistor inverter by obtaining sufficient reverse bias voltage by utilizing the counterelectromotive force of an inductor, thereby shortening the turn OFF time. CONSTITUTION:When a transistor 2 is turned ON, a current flows from a power source 1 through the collector, base of the transistor 2 and the capacitance of an inductor 10, and the waveform of the voltage and current of the inductor 10 at this time become as shown by (a), (b) in figure. Thus, the transistor is conducted ON irrespective of the base current flowing inversely at the rear half of the ON period of the transistor 2. Accordingly, considerably large current will flow as a part of the current flowing through the input coil 4, and when the transistor 2 is interrupted and hence the current is interrupted, a peak voltage is produced. This peak voltage is operated to turn OFF the transistor 2, thereby rapidly turning OFF the transistor, thereby alleviating the power loss at the time of turning OFF the transistor.

Title: Method for measuring relative displacement
Inventor: KANAYAMA TOSHIHIKO
IPC: G03F9/00
Filed: 1986-01-27
Abstract: PURPOSE:To make it possible to measure the relative displacement of a plurality of objects with high accuracy, by providing a diffraction lattice on one object and measuring the phase of the diffracted wave obtained by diffracting a wave motion with the diffraction lattice. CONSTITUTION:Diffraction lattices G1, G1' each having the same cycle as a diffraction lattice G2 are arranged on object 1 at positions irradiated with a diffracted wave generated by diffraction lattice G2. The phase difference phi between the wave D diffracted by the diffraction lattice G2 and further diffracted by the diffraction lattice G1 to advance in the direction opposite to a direction I and the wave D' successively diffracted by the diffraction lattices G2, G1' is measured by detectors 4, 5. The phase difference phi is not dependent on the distance S between matters 1, 2 at all and proportional to the relative displacement (x) between the matters 1, 2 in the direction (x- direction) parallel to the surfaces of the diffraction lattices G1, G1', G2 and crossing the directions of the diffraction lattices at a right angle and phi=4pi.nmu/d(radian) is defined. This is an extremely simple result as compared with a case where the intensity of the wave D or D' is dependent on S or (x). Therefore, by measuring the phase difference phi, (x) can be measured regardless of S and the value of proportion coefficient S/d can be easily measured with high accuracy.
