Title: Optical recording material
Inventor: HIRONO TAKUSHI
IPC: G03C1/73
Filed: 1982-03-31
Abstract: PURPOSE:To make fixing unnecessary and to enable simple recording and erasing by using silver pyrophosphate as an optical recording material. CONSTITUTION:Silver oxide is mixed with ammonium hydrogenphosphate in 1:1 molar ratio, and the mixture is press-molded and calcined at 400 deg.C on a platinum plate for 6hr to obtain light-yellow crystalline silver pyrophosphate powder. The powder is baked and pelletized to form a crystalline pellet. When the pellet is irradiated with light having 450nm wavelength under the condition of 200mJ/cm<2>, the spectral reflectance to light in a wavelength region of >=about 600nm wavelengths is reduced by about 10%, and the reflectance is restored by heating to 500 deg.C. When a single crystal grown from a melt of the silver pyrophosphate powder is irradiated with light having 330nm wavelength, the spectral reflectance in a region ranging from the visible region to the infrared region is reduced in accordance with the intensity of the irradiation, and the reflectance is restored by heating. Thus, an optical recording material requiring no fixing and enabling simple recording and erasing is obtd.

Title: Motor power steering
Inventor: HAYATA KAZUO
IPC: B62D5/04
Filed: 1988-03-07
Abstract: PURPOSE:To prevent rolling of steering wheel by shortcircuiting the terminals of a steering assist motor upon detection of no steering force. CONSTITUTION:A motor power steering is provided with a means M1 for detecting the existence of steering, nod when steering is detected through the steering detecting means, a motor M2 is driven to perform steering assist. When steering is not detected through the means M1, terminals of the motor M2 are shortcircuited through a shortcircuit control means M3. When the motor M2 is shortcircuited, the motor M2 is constituted as an engine. When the motor M2 is rotated through disturbance applied onto the steering system, the motor M2 functions as a generator for generating current between the shortcircuited terminals. Consequently, the generating resistance of the motor M2 resists against the disturbance thus preventing rolling of the steering wheel.

IPC: B23H7/18
Filed: 1980-04-23
Abstract: PURPOSE:To contrive so that the sludge or dust staying in a clearance may be  removed by detecting an interpolar clearance and controlling the amplitude of an  electrode feeding servo system with the help of the detection output. CONSTITUTION:A digital scale 34 installed on an electrode support bar 32 generates a pulse SP in a plus direction when the electrode 10 descends. While the said scale generates a pulse SN in a minus direction when the electrode ascends. These pulses are inputted to a reversible counter 36. A count value on the reversible counter 36 represents a difference between the optimal position where the electrode 10 is fed toward a work 14 and the present position of the electrode 10. This count value is converted to an analog signal by means of DA converter 40 and then is inputted to a circuit GC which controls an amplitude of an interpolar servo system.

An air-fuel ratio sensor 22 for detecting the air-fuel ratio of intake air-fuel mixture is provided on an exhaust passage 21, and a catalytic converter 23 is interposed, moreover an exhaust gas temperature sensor 17 is attached. When the control units 50 judges that the engine driving state is in the state where it can perform the catalyst deterioration diagnosis, it fixes the air-fuel ratio to the fixed air-fuel ratio on the rich side or the lean side in relation to the stoichiometiric air-fuel ratio and detects the reference exhaust gas temperature after passing the catalyst. Next, it detects the comparative exhaust gas temperature by changing the air-fuel ratio to that on the reverse side of the rich side or the lean side. The difference of the temperature is compared with the fixed temperature difference previously stored, and when it is diagnosed that the catalyst is deteriorated the signal is output to a warning light 20. Thus, the unevenness of the temperature detection is eliminated and precisely diagnosed.

Title: Signal detecting method for phase change type optical recording medium
Inventor: HARIGAI MASATO
IPC: G11B7/30
Filed: 1990-03-06
Abstract: PURPOSE:To detect a signal by high CN ratio by using the difference of an outgoing polarized light characteristic for incident linearly polarized light between recorded/unrecorded parts due to the phase change of a crystaline substance between the crystaline substance and a non-crystaline substance. CONSTITUTION:When an optical axis 6 makes an angle theta against the vibrating direction of the incident linearly polarized light, in an optical recording medium 1, the incident linearly polarized light advances as being separated into a linearly polarized light component inclined at the angle theta against the incident linearly polarized light and the linearly polarized light component vibrating perpendicularly to it. Phase difference is caused from the difference of a refractive index for the respective components, and after being transmitted through the medium 1, it enters an analyzer 4 as elliptic plarized light. Even if the analyzer 4 is in a cross nicol state, a part of the light is transmitted through the analyzer 4, and a light receiving element 5 outputs signal detection output, and it can be distinguished from the recording part of output '0'. In the case the optical axis 6 is parallel with or perpendicular to the vibrating direction of the incident linearly polarized light, a double refraction phenomenon is not observed, and the output is 0. Through this configuration, the signal can be detected by the high CN ratio, and recording sensitivity too can be improved by thinning a recording medium layer.

Title: Decision processing system of character shape
Inventor: MEGURO SHINICHI
IPC: G06K9/62
Filed: 1979-05-02
Abstract: PURPOSE: To decide a hand-writing character by hierarchically deciding a minute shape from a rough shape of a character.  
     CONSTITUTION: An input 1 which has been obtained by scanning is converted photoelectrically and is provided to a gradation processing part 3. The gradation processing part 3 provides to an input signal three kinds of gradation such as large gradation, a little large gradation and slight gradation. A stroke which has added the afore-mentioned three gradations is decided in a mask pattern decision part from a reference character stroke stored in a character stroke memory part 4. In shape decision parts 6, 7, 8, a stroke which has been gradated in the mask pattern decision part 5 is made to correspond to each gradation output of the gradation processing part 3 in order to detect a similar part. A degree of deformation of an input character is decided in a character deformation amount decision part 9 by a character shape which has been decided in due order in the decision parts 6, 7, 8. Since a shape is decided hierarchically, a hand-writing character can be decided stably.
