Title: Thermal type infrared detecting device
Inventor: HANAMURA AKIHIRO
IPC: G01J5/48
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To surely conduct off-set correction even in the case of a large number of detection elements, and to eliminate a blank time for an output. SOLUTION: This device has plural blocks A, B of which each block is provided with a circuit comprising plural detection elements 1A-4A, a correction element 5A, a means for switching in order signals of the detection elements 1A-4A and the correction element 5A to be output, a memory means for storing the signal of the element 5A in every supplied time as a correcting value, and a means for correcting using the correcting value the signals of the elements 1A-4A in every supplied time to be output. Correction and output for the detection element signal are conducted in one block when the correcting value is stored in the other block, and the processing therebefore is circulated sequentially for the respective blocks.  Since the correction value is updated in every signal detection for the detection elements 1A-4A, a holding time for the memory means is minimized even in the case of increasing the element 1A-4A. Since the signals of the elements 1A-4A are output in one block when the correcting value is stored in the other block, a blank time when output voltage gets zero is eliminated.

Title: Semiconductor light emitting device and manufacture thereof
Inventor: TSUJIMURA AYUMI
IPC: H01S5/00
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a II-VI compound semiconductor light emitting device. SOLUTION: An n-type GaAs layer 102, an n-type ZnSe buffer layer 103, an n-type ZnMgSSe clad layer 104, a strain multiple quantum well structure 107 composed of four Zn0.8Cd0.2Se well layers 105 and five ZnS0.2Se0.8 barrier layers 106, a p-type ZnMgSSe clad layer 108, and a p-type ZnSe contact layer 109 are stacked on a GaAs substrate 101. As the ZnSSe barrier layer 106 having an S composition ratio of 0.2 is used, a tensile strain acting on the barrier layer compensates a compression strain acting on the well layer. Therefore, the strain acting on the strain multiple quantum well structure 107 and the vicinity thereof is offset almost perfectly, thereby providing a non-strain state as a whole. Thus, generation of and increase in defects in the well layers 105 are restrained, thus enabling improvement in reliability of the device.

Title: Oscillatory wire-leaving measuring instrument
Inventor: MORIKAWA TAKEO
IPC: G01M17/08
Filed: 1982-06-10
Abstract: PURPOSE:To obtain an oscillatory wire-leaving measuring instrument which is attachable to any kind of pantagraph and detects leaving and contacting between a tolley wire and the pantagraph, by transducing mechanical oscillation that generate at the pantagraph during a run into an electric signal and then processing it electrically for deciding on a specific waveform. CONSTITUTION:Acceleration signals outputted from accelerometers 14 and 14' each contain various components of low-high frequencies, so mixed waves are amplified temporarily by amplifiers 15 and 15' and then passed through high- pass filters 16 and 16' to select only high frequency components generated during sliding. After they are rectified on full-wave basis by rectifying circuits 17 and 17', low-pass filters 18 and 18' discriminate only phenomenal waveforms in wire leaving and they are shaped by shaping circuits 19 and 19' into easy-to- process shapes. The shaping circuit 19 deals with a phenomenon from a pantagraph sliding plate 13 and the shaping circuit 19' deals with a phenomenon from a pantagraph sliding plate 13', so they output different waveforms. Those two waveforms are inputted to an AND circuit 20 and at the same time, their common waveform is selected and outputted as a wire-leaving data.

Abstract: PURPOSE:To obtain good printing generating no density irregularity by making it possible to always perform transfer by the optimum transfer energy, by estimating the opening ratio of a transfer medium from the recording electric energy within a range performing transfer by one light emission measured by a measuring means and controlling light emission energy corresponding to said opening ratio. CONSTITUTION:A mask sheet 15 is sent in a direction shown by an arrow and superposed on recording paper 16. When a xenon flash lamp 17 is allowed to emit light, light transmits through the part where a metal vapor deposition film 15b is removed of the mask sheet 15 and reflects from the part where the metal vapor deposition film 15b remains and, therefore, heat-meltable ink 15c receives light corresponding to a pattern to generate heat and is melted to he transferred to the recording paper 16. Since the area where the metal vapor deposition film 15b is removed is almost proportional to the current flowing to a recording electrode 11, when the electric energy thereof is measured, the omission area of the metal vapor deposition film 15b, that is, the opening ratio of the mask sheet within a range to be transferred by one light emission of the xenon flash lamp 17 can be known and the optimum light emission energy can be calculated.

Title: Logarithmic amplifier for very small current and color identification sensor circuit using it
Inventor: FUJIMOTO KIMITADA
IPC: H03F3/08
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce the effect of an input offset current, to decrease a conversion error at a very small current region, and to extend a usable input current region by adding a current amplifier stage amplifying an input current to an input stage of the logarithmic amplifier. SOLUTION: The logarithmic amplifier is made up of a current amplifier stage 3 amplifying an input current, an operational amplifier 4 receiving an output of the current amplifier stage 3, and a log diode 5 giving feedback to the operational amplifier 4. Since the current amplifier stage 3 is added to an input of the operational amplifier 4, a ratio of a bias current of the operational amplifier 4 with respect to the input current is reduced and then the effect of the conversion error up to the very small input current region is reduced. When the amplification factor of the current amplifier stage 3 is, e.g. 10, the bias current Ib of the operational amplifier with respect to the input current is 1/10 and an error is reduced up to a 1/10 conversion region.  Even when the input current is smaller than the bias current Ib of the operational amplifier, an output without error is obtained by selecting the current amplification factor to be higher moreover.
