Title: Disk defect inspecting device
Inventor: HANAKAWA EIICHI
IPC: G01N21/88
Filed: 1981-02-16
Abstract: PURPOSE: To sufficiently detect whether a defect exists or not on a disk, even when the disk is rotated faster than a prescribed value, by irradiating a laser beam diagonally onto the disk, making a light spot elliptical, and widening the detecting range.  
     CONSTITUTION: Incident laser beams 4 are parallel light beams whose section is a circle (a), but when they pass through a condencer lens 5, they become a luminous flux whose section is a very small circle (b), at its focal position. The luminous flux is cut diagonally against a disk 1, therefore, on the disk surface, a light spot of a short ellipse (c) is irradiated in the long circumferential direction in its radial direction. Accordingly, the detecting range in the radial direction of the disk is expanded. On the reflection optical axis, a mask for intercepting a diffracted light beam by a concavo-convex lens showing an information signal, and a photodetecting lens and a photodetecting element positioned just behind said mask, for photodetecting scattered light beams due to a defect of the disk, which have passed through the mask are placed.

Title: Copying device compensating for fatigue of photosensitive body
Inventor: IWAHASHI HARUO
IPC: G03G21/00
Filed: 1987-02-04
Abstract: PURPOSE:To prevent a copy image from being changed at its density by providing the titled device with a non-volatile memory for storing the degree of fatigue generated up to the end of the preceding copy as compressed information and allowing the device to read out the degree of fatigue from the memory at the start of copying and determine an initial correcting value for compensating the fatigue in a suspending time updated and stored in the memory. CONSTITUTION:Although inconvenience may be remarkably generated when copying operation is continued under always the same condition, the fatigue is recovered in accordance with a stopping period at the time of stopping the use. Thereby, the fatigue is compensated by correcting the charging value or exposure amount. Since the degree of fatigue is determined based on the degree of fatigue generated up to the end of the preceding copying operation, the suspending period from the end of copying up to the start of correct copying and the current copying time, the correcting value may be controlled under the consideration of these factors.

Abstract: PURPOSE: To improve operation and maintenance by starting an engine, cutting off electrical power and stopping a vehicle by foot with a circuit for controlling the rotation/stop of a start motor using feedback of output voltage of a generator. CONSTITUTION: A start motor M is rotated via a relay 15 when a switch 1 is set to GT by manual operation. An engine is started when an accelerator 3 is stepped on. After start, when the switch is returned to ON the motor M is stopped and the engine is stopped when the switch is set to OFF. When an on-off switch 7 is transferred to the automatic side, the start motor M is actuated and the engine is started via a stabilizing circuit 8, a trigger circuit 9, a timer circuit 10 and a control circuit 11 by stepping on the accelerator 3. After start, the start motor M is stopped via the circuit 11 by the output voltage of a generator 4. When the accelerator 3 is released and a brake paddle 2 is stepped on, the engine is braked and stopped so that the vehicle is stopped. Thus operation is simple, and repair can easily be conducted in case of breakdown.

Title: Picture density control method
Inventor: HASEGAWA MAKOTO
IPC: G01M11/00
Filed: 1988-02-01
Abstract: PURPOSE:To minimize the error produced in a copying device so as to improve the quality of the product of the copying device by controlling the picture density after the output levels of photosensors caused by the variance of the sensitivity is corrected. CONSTITUTION:Variance of the output voltages between photosensors occurs even due to the difference in fitting positions of the sensors or the error of an optical system in addition to the variance of the sensitivity of the sensors in a state where the toner adhering quantity is at or less than 1.5 times (6mg/cm<2>) of a set quantity (4mg/cm<2>). However, it is expected that the variance of output voltages between the photosensors depends mainly upon the variance of the sensitivity of the sensors in the area where the toner adhering quantity exceeds the 1.5 times of the set quantity. Therefore, a high-density reference- pattern toner image whose toner adhering quantity to set to >=1.5 times of the set quantity is formed on a carrier and the then toner adhering quantity is optically detected and outputted. The output value is related to the ordinary- density reference-pattern toner image obtained at every prescribed number of copies and the output value is corrected.

Title: Magnetic field sensor
Inventor: TSUJI KOJIRO
IPC: G02B5/04
Filed: 1986-02-03
Abstract: PURPOSE:To enlarge a modulation degree by absorbing the shift of manufacturing accuracy, by using material quality having a refractive index larger than that of glass in a right-angled prism allowing incident light to pass through a Faraday effect element two times. CONSTITUTION:The incident light to a refractive index distributing lens 10 is converted to linear polarized light by a polarizer 11 while said polarized light is provided with a right pi/8 bias angle by a polarimeter 12 and rotates in proportion to the intensity of a magnetic field in a Faraday effect element 13 and is reflected and reversed two times by a ZnSe right-angled prism 18 to take out emitting light modulated in the reverse route. Because the prism 18 comprises a II-VI compound having a refractive index larger than that of glass and has no optical rotatory power, a total reflection incident angle comes to 30 deg.C or more and a problem is eliminated even if angular shift of about 2 deg. is generated at the fixing time of the lens. As mentioned above, by absorbing the shift of manufacturing accuracy, a magnetic field sensor enhanced in a modulation degree can be obtained.

Abstract: PURPOSE:To keep a constant distance between a reading area and a sensor by securing such a constitution where one of two guide plates energizes elastically a medium to the other guide plate in a bar code reading state and a positioning bar of a holding case touches and rubs the latter guide plate with elasticity in accordance with the shift of a sensor driver. CONSTITUTION:When a bar code is read, a medium 30 is elastically energized to a 2nd guide plate 12 and therefore positioned with a 1st guide plate defined as a reference level. At the same time, a positioning bar 24a functions to keep a prescribed distance between a bar code sensor 9 held by a holding case 24 of a sensor driver 10 and the plate 11. Thus a stable distance is secured between the reading area of the medium 30 and the sensor 9. Furthermore the medium 30 is never damaged nor soiled since no contact is secured between the medium 30 and the bar 24a.

Title: Element for sonar transmitter
Inventor: FUJITA HAJIME
IPC: H04R17/10
Filed: 1986-02-07
Abstract: PURPOSE:To improve the efficiency of a sonar transmitter by determining the size of a matching element so that the resonant frequency including a damping capacity effect for a piezoelectric element and the resonant frequency of the matching element coincide with each other. CONSTITUTION:When a piezoelectric element 1 is driven by a voltage E, an electric field is produced in the piezoelectric element 1 and, when the electric field is parallel to the direction of an oscillation, a capacitance CE is applied that is associated with a damping capacity based on the electric field. The capacitance Cf of a resonant circuit is expressed by expressions I and II, wherein e<2>SS, epsilonSSS and CDSS designate a piezoelectric constant, a permittivity and an elastic stiffness, respectively. Accordingly, a true resonant frequency is reduced by about 10% as mentioned in an expression III. When a matching element 2 of a 1/4 wavelength is mounted, quantities based on a mechanical compliance and a mass are represented by C2 and M2, respectively. A length l1 is set as mentioned in an expression IV so as to make the resonant frequency equal to that of the piezoelectric element. By combining the piezoelectric element with such a size and the matching element with each other, the resonant frequencies coincide with each other and the efficiency of a sonar transmitter can be improved.
