Title: Oxygen concentration sensor for internal combustion engine
Inventor: ITOU TOSHIBUMI
IPC: G01N27/406
Filed: 1981-11-12
Abstract: PURPOSE:To prevent the abrupt deterioration of a heater by having an electric power source supplying means which conducts electricity to the heater according to the operating condition of an engine. CONSTITUTION:When an ignition switch turns on in the stage of low temp. starting of an engine, the output of a comparator 9 is at a low level; therefore a switch circuit 7 is off and no electricity is conducted to a heater 4, but when a waste gas is fed into an exhaust pipe and the temp. in the exhaust pipe rises and attains a prescribed temp., the output of the comparator 9 inverts from the low level to a high level according to the output voltage of a temp. sensor 8, by which the circuit 7 is turned on, thus the temp. of a ceramic pipe for heating of the heater 4 rises to high temp., the operating characteristics of the oxygen concn. sensor are improved and the air to fuel ratio is controlled adequately. When the temp. in the exhaust pipe attains a prescribed temp. T2, the output of the comparator 9 inverts from the high level to the low level according to the output voltage of the sensor 8 and the circuit 7 goes on again, thereby stopping the conduction of electricity to the heater 4.

Inventor: WADA SATOSHI
IPC: F23J15/00
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a combustion control device for a refuse incinerator capable of avoiding a state in which a non-required large amount of NOx is generated while reducing carbon monoxide and restricting an amount of occurrence of dioxine by a method wherein a combustion condition is changed in response to quality of refuse with a concentration of hydrogen chloride being applied as an index.

A gas sensor 9 for use in sending a concentration of hydrogen chloride gas contained in the gas is mounted as a downstream side of the dust collector 13. A wet-type desalting device 14 is arranged at a downstream side of it. There is provided a combustion control means 7 for carrying out a combustion control under a low CO combustion control mode if a concentration of hydrogen chloride detected by the gas sensor 9 is higher than a reference value, and for carrying out a combustion control under a low NOx combustion control mode if the concentration of hydrogen chloride is lower than a reference value.

Title: Detection of cartridge gear engagement state in magnetic tape device
Inventor: YAMAMOTO TAKAO
IPC: G11B15/675
Filed: 1990-07-09
Abstract: PURPOSE:To avoid system down due to a defect of cartridge loading and to obtain a magnetic tape device of high reliability by settling the driving gear engagement detecting method. CONSTITUTION:A control circuit supplies a driving current to a reel driving motor 24 to monitor the tacho pulse of an encoder 25. When it cannot be confirmed, it is judged that a clutch 11 is not rotated, and the driving current is successively increased. If the tacho pulse is not generated though the driving current exceeds a limit current, driving is stopped, and a cartridge 1 is loaded again. If the same result is obtained even after this operation is executed for a prescribed number of times, trouble other than driving gear engagement is decided. When the tacho pulse can be confirmed, a command is issued to a motor driving circuit 29 to drive a threading motor, and a pantoarm is driven to thread a magnetic tape 2. Thus, system down due to a defect of driving gear engagement is avoided to obtain a magnetic tape device of high reliability.

Title: Sheet having resistance to deformation at high temperature and its manufacture
Inventor: SETO HIROYUKI
IPC: B22F3/24
Filed: 1986-08-04
Abstract: PURPOSE:To manufacture a sheet having high resistance to deformation at high temp. and causing cracking in four directions when deformed in an Erichsen test by rolling an ingot in one direction until a specified draft is attained and by further rolling it to the final thickness in a direction perpendicular to the rolling direction. CONSTITUTION:When an Mo or W alloy ingot as stock for a panel heater is rolled to the final thickness at 100% draft, the stock is rolled in one direction until 76-84% draft is attained and then it is rolled to the final thickness in a direction perpendicular to the rolling direction. Thus, a sheet causing cracking 1 in four directions as shown by the figure when deformed in an Erichsen test is obtd. Since the grains of the stock are uniformly drawn in the longidudinal and lateral directions, the sheet reacts uniformly to strain and the grain boundaries have uniform strength. Accordingly, a panel heater having high resistance to deformation at high temp. is obtd.

Title: Battery-consumption display device
Inventor: DOKE TAKAHIRO
IPC: G01R31/36
Filed: 1987-07-21
Abstract: PURPOSE:To display the used-up state of a battery continuously only by applying a voltage temporarily, by using an electrochromic display element as a display element. CONSTITUTION:The voltage of a battery 1 is also supplied to a consumption detecting part 2. The voltage of the battery 1 is compared with a predetermined reference voltage. Thus the consumption of the battery is detected. The detecting part 2 functions as a voltage switch, which applies a voltage to an electrochromic display part 3 when the voltage of the battery is lower than the reference voltage. The display can be maintained for a long period only by applying the voltage temporarily when the consumption of the battery is detected, by using the electrochromic display element as the display element of the display part 3. Therefore, the used-up state of the battery is continuously displayed without accelerating the power consumption of the battery, which is in the consumed state.

Title: Image sensor
Inventor: JIYAROSURABU HAINESETSUKU
IPC: H01L29/762
Filed: 1992-07-10
Abstract: PURPOSE: To achieve a charge-multiplying capacity inducing the collision ionization of a charge carrier in a CCD cell. CONSTITUTION: A DC-biased transfer barrier is formed below an electrode 56 with a phase 3, and a temporary accumulation well is formed below an electrode 54 with a phase 2. When the biasing of the electrode 54 with a phase 2 decreases, an accumulated charge is injected to a high electric field region between the electrode 56 with a phase 3 and the electrode 58 with a phase 4 over a transfer barrier below the electrode 56 with a phase 3. While a carrier travels in a CCD channel, it collides with a lattice atom and releases additional electrons from a valence electron band when an electric field in the channel is sufficiently strong and leaves a collision region along with positive holes and electrons being generated due to the collision and becomes free.  A pair of electron and positive hole is separated by an electric field in a direction that is vertical to the surface of a CCD during the collision ionization, only electrons are gathered in a well below the electrode 58 of the phase 4, thus multiplying the electrons.

The separated seeds are fed to a second seed adjusting conduit 4. The seeds dropping from the seed outlet end 2b are detected by a seed sensor 6, the angle of inclination of the seed adjusting conduit 2, the amplitude and intensity of the oscillating device 3 are controlled depending upon the amount of the seeds dropped. The intervals of the seeds are further made constant by the second seed adjusting conduit 4.
