Title: Optic axis length measuring instrument
Inventor: SEKINE AKIHIKO
IPC: A61B3/10
Filed: 1991-03-20
Abstract: PURPOSE:To measure an optic axis length at a high speed without depending on the wavelength of a laser beam source, a wavelength change characteristic arising from a temp. change and output change characteristic if slight frequency waves are obtd. CONSTITUTION:The laser beam source 1 is changed in wavelength by a laser driving section 2 and the eyeball is irradiated with coherent light of single wavelength. A 1st photodetecting section 11 is outputted by the interference light of the cornea C and the eyeground R. A reference interferometer 6 is longer than the optical path difference of the optic axis length and a 2nd photodetecting section 24 is outputted by the interference light of the reference interferometer 6. An electrical filter 24 cuts the noise contained in the output of the 1st photodetecting section 11 in at least a part of the wavelength change section of the laser beam source 1. A sampling wave forming section 21 samples the output of the 1st photodetecting section 17 with the output CO of the 2nd photodetecting section as a timing signal C2. An arithmetic section 23 forms the frequency waves in accordance with the sampling waves and determines the optic axis length AL by the optical path difference of the reference interferometer 6 and the period of the frequency waves. The arithmetic section 23 decides whether the frequency waves can be formed or not.

Title: Semiconductor device
Inventor: HASEGAWA HIROSHI
IPC: H01L29/732
Filed: 1986-03-14
Abstract: PURPOSE:To improve the effective current amplification factor of an inverter by reducing the reverse current amplification factor of a lateral transistor in I<2>L. CONSTITUTION:An I<2>L inverter collector 7, an emitter electrode leading region 8 and a lateral transistor reverse current amplification factor decreasing region 9 are simultaneously formed in N<+> type diffusion, and electrodes 10 are eventually formed. The N<+> type region 9 for reducing the reverse current amplification factor beta1 of the lateral transistor contacts an inverter base and is separated from the lateral transistor emitter. In the I<2>L of such a configuration, the region 9 of the lateral transistor and the emitter separated, and it does not almost change, but since the N<+> type region contacts the collector of the lateral transistor, electrons implanted from the base to the collector are increased to decrease the reverse current amplification factor beta1. Thus, even if the upper current amplification factor betaUP of a reverse structure vertical transistor is the same, an inverter effective current amplification factor betaeff is increased.

Title: Crystal oscillation circuit
Inventor: KATOU MASAAKI
IPC: H03B5/36
Filed: 1978-05-17
Abstract: PURPOSE:To obtain an oscillation circuit which is self-actuated even if a direct resistance is increased for the purpose of reducing a penetrating current. CONSTITUTION:The source of P-channel transistor TP is connected to the high- potential VDD side and its drain is to the drain of N-channel transistor TN via resistances R1 and R2. The source of TN is connected to the low-potential VSS side, and its gate is connected to the gate of TP and also to the drain via resistance RF. As for input-output characteristics, selecting sufficiently-large resistances R1 and R2 for the purpose of reducing a penetrating current nearly flattens an output voltage around where the output voltage is inverted, but since a bias voltage applied to the gate is caused to approximate to the threshold voltage of Tnu by feedback resistance RF, operation point P at the time of an oscillation start is shifted from the flat part to where the gain is enough. Consequently, self-actuation becomes possible.

Title: Catalytic heater power supply control unit
Inventor: FUKUCHI HIRONAO
IPC: F01N3/20
Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent excessive rise of temperature of a current carrying heater when increased fuel is supplied, by providing a power setting means that sets supply power value lower as the detected air-fuel ratio of engine gets richer, and by supplying power to the current carrying heater according to the supply power value immediately after the start of the engine. SOLUTION: When an engine 22 starts, an air-fuel ratio feedback is controlled so that an air-fuel ratio feedback correction coefficient is 1. In addition, immediately after the start of the engine 22, a fuel injection time is set larger as the temperature of the engine 22 is lower. When the fuel injection time is larger than the threshold at the engine start, a voltage applied to the heater is set low corresponding to the fuel injection time. Accordingly, even when unburned components increased in the exhaust gas in a driving condition where increased amount of fuel is supplied, if a current carrying heater 1 is heated with the combustion heat of the unburned components, the rise of the heater temperature up to the tolerable upper limit temperature of the current carrying heater 1 is prevented.
