Title: Film thickness measuring method
Inventor: MIHARA TOSHIAKI
IPC: G01B11/06
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To measure the film thickness of a material with high accuracy by irradiating the material with light from a light source composed of flash lamps having bulbs that transmit infrared rays in specific wavelengths and receiving light rays having a plurality of wavelengths of irregular reflected light rays from the material, and then, calculating the intensity ratio of the infrared rays. SOLUTION: A material 1 to be measured is irradiated with light rays from flash lamps 21-1 and 21-2 and the irregular reflected light rays 41 from the material 1 are introduced to an integrating sphere 33 where the intensities of the reflected light rays are measured by means of light receiving devices 31 and 32 for first and second wavelengths. Each measured value is converted into the thickness of a film 11 on a substrate 12. Since the bulbs of the flash lamps 21-1 and 21-2 are made of silica glass, sapphire, etc., the lamps 21-1 and 21-2 can take out infrared rays having wavelengths of >=2.5 μm and applied to the absorption and measurement of the wavelength characteristic to a coated or applied material. The material 1 is run in the direction shown by the arrow 5 and, during the course of running, the material 1 vibrates or makes vertical motions.  Since the substrate 12 and film 11 also vibrate or make vertical motions, the measurement error due to running is suppressed.

Title: Thermal-type recorder
Inventor: HAGIWARA SHIGEMI
IPC: B41J2/38
Filed: 1985-08-28
Abstract: PURPOSE:To reduce power consumption and secure excellent recording quality with high transfer efficiency, by providing a thermal head with a constant-temperature heating element having a self-controlling function for maintaining a constant surface temperature. CONSTITUTION:A constant-temperature heating generating element 7 consists of a PTC thermistor obtained by adding minute amounts of oxides of rare earth elements or Bi, Nb, Sb or the like to BaTiO3, followed by firing the admixture. The thermistor has such a characteristic that the resistance thereof is rapidly increased when a certain temperature is exceeded, and owing to the temperature-resistance characteristic, the thermistor has a self-controlling function for maintaining a constant surface temperature. A preheating voltage is applied to the PTC thermistor (the heating generating element 7) simultaneously with switching ON a power source for the printer. The thermistor instantaneously reaches the preset preheating temperature, the surface temperature is stabilized, and excellent current-limiting characteristics are displayed through self-regulation of the resistance. Accordingly, even where a large quantity of electric current is passed at the time of normal temperature, the current can be largely reduced after a lapse of time, and the preheating temperature of the thermal head is maintained at a preset temperature, so that printing quality is enhanced, and power consumption in preheating the head is reduced.

Abstract: PURPOSE:To suppress the characteristic deterioration of a cell by detecting the internal resistance of the cell during the operation by the AC four-terminal method and adding steam into the reaction air when the internal resistance is increased to supply moisture to the holding matrix or a phosphoric acid electrolyte. CONSTITUTION:An internal resistance measuring instrument 4 by the AC four- terminal method is provided between terminals of a cell, and the internal resistance is measured during the cell operation. When the resistance value becomes 1.2-1.5 times of the initial value, the signal 4' of the detector 4 is sent to an actuator 7, a steam feed valve 8 is opened, and steam 9 is fed to a humidifier 6. The reaction air quantity is changed in response to the fluctuation of a cell load, this change is detected by a flow detector 5, a valve 8 is adjusted by an actuator 7 so that the steam addition ratio is not changed. Steam 9 is absorbed into the phosphoric acid electrolyte in a matrix M, and moisture is supplied to the electrolyte. As a result, the internal resistance is reduced, and the characteristic deterioration of the cell is suppressed.

Title: Abnormality detecting device for rotational speed
Inventor: BAN MITSURU
IPC: F02D41/34
Filed: 1986-08-08
Abstract: PURPOSE:To improve the detection accuracy of a rotational speed or the control accuracy of an engine by calculating a pulse interval by a microcomputer and deciding whether this pulse interval is abnormally larger or smaller than the last pulse interval. CONSTITUTION:Projections and recesses of teeth of a gear for rotating speed detection which is coupled directly with a column type fuel injection pump driving shaft are detected by an electromagnetic pickup 8. Then the obtained analog output is waveform-shaped 15c and then the microcomputer 15a calculates the pulse interval tn. Then, this interval tn is compared with the (A)th multiple of the last pulse interval tn-1 and decided as a normal pulse interval when tn>AXtn-1. If not, i.e. if it is decided that tn is abnormally smaller than tn-1, the interval tn is disregarded and (n) is increased to control the internal combustion engine by using only the normal rotational speed. Further, when tn is abnormally larger, tn is substituted with 1/2tn, so an error from the actual rotational speed becomes small even when the rotational speed of the internal combustion engine has large variation, thereby improving the accuracy.
