Title: Optical disk device
Inventor: HAYASHI SHIGEO
IPC: G11B7/085
Filed: 1987-10-02
Abstract: PURPOSE:To prevent deterioration of performance of an optical head from being incurred by providing a means interrupting a drive current of a head actuator driving a carriage independently of the result of detection so as to prevent a head actuator from crashing an outer wall or the like. CONSTITUTION:A carriage 4 mounted with part or all of an optical head comprising photodetectors 47-49 detecting a reflected luminous quantity of a ray and focus and tracking actuators 50, 52 mounting a condenser lens 44 forming a ray spot onto a track on a recording face 1a of a rotated optical disk 1, is subject to speed control in the track crossing direction of the optical disk based on an external command. Then in detecting that the focal spot of the ray is largely deviated from the recording film 1a of the optical disk, the current of the head actuator 52 driving the carriage is interrupted. Thus, the acceleration of the carriage attended with disabled speed control is prevented and the shock attended with the runaway is reduced considerably and the shock resistance is enhanced, then the device is formed inexpensively and the reliability is improved.

Title: Hazardous substance fixing material
Inventor: ICHIKAWA ATSUSHI
IPC: B09C1/08
Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To inexpensively and surely fix hazardous substances such as heavy metals by mixing a substance having a rehydration property, obtained by heating treatment of calcium sulfoaluminate hydrate, and one or more kinds among an inorganic acid salt of iron, a sulfide or hydrosulfide of an alkali metal or an alkaline earth metal, and a thiourea. SOLUTION: For producing a fixing material, first of all calcium sulfoaluminate hydrate is synthesized and then is subjected to a heating treatment, so that its crystal structure is destroyed and converted to an amorphous state. Subsequently the substance after the heating treatment is mixed with one or more kinds among an inorganic acid salt of iron, a sulfide or hydrosulfide of an alkali metal or an alkaline earth metal, and a thiourea, thereby improving a hazardous substances fixing property. At this time, selecting the materials under condition that they are available and inexpensive, iron sulfate is preferable as the inorganic acid salt of iron, and sodium sulfide, calcium sulfide, etc., are preferable as the sulfide or hydrosulfide of the alkali metal or the alkaline earth metal.  As a result, hazardous substances such as heavy metals are fixed surely and inexpensively to be detoxified.

Title: Power transmission device for vehicle
Inventor: OZAKI RYUJI
IPC: F16H37/02
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To establish a forward driving system and a backward driving system without a hitch when driving force from a power unit is inputted into the input shaft of a forward/backward driving change-over mechanism. SOLUTION: An auxiliary transmission Ts equipped with a forward/backward change-over mechanism C and a differential gear D is equipped with an input shaft 45 to which the driving force of forward rotation is transmitted from a power unit diverted from a motorcycle by way of an endless chain 29. When a sleeve 77 is driven to the right direction, the forward rotation of the input shaft 45 is transmitted to the final driven gear 59 of the differential gear D as a forward rotation by way of three forward gears 51, 53 and 54, a forward gear shifting step is thereby established. When the sleeve 77 is driven to the left direction, the forward rotation of the input shaft 45 is transmitted to the final driven gear 59 as backward rotation by way of a reverse gear 52, a backward gear shifting step is thereby established.

Title: Synchronizing circuit for dot sequential color multiple signal
Inventor: NISHIYAMA HIROSHI
IPC: H04N9/07
Filed: 1988-09-30
Abstract: PURPOSE:To prevent the generation of a color pseudo signal by separating a read dot sequential color multiple signal into respective R, G and B chrominance signals by means of a prescribed separating clock at different phases, and latching the R, G and B signals passing through a definite transient response filter at a prescribed sample clock. CONSTITUTION:The dot sequential color multiple signal is latched by a clock fs whose phases are dislocated by 120 deg. mutually by R(red), G(green) and B(blue) latches 4 to 6. Further by FIR filters (definite transient response filter) 7 to 9, the respective R, G and B chrominance signals are made into the new chrominance signals generated by the chrominance signal adjacent before and after the signals in time, and thus, the output of a light receiving element, whose physical positions for the respective chrominance signals are dislocated, is leveled. Consequently, the level difference among the R, G and B chrominance signals due to the physical position dislocation of the light receiving elements of the R, G and B of the line sensor 2 is reduced. Thus, the generation of the color pseudo signal is drastically reduced, and the correct color can be reproduced.

Title: Solid-state image pickup element and measuring method therefor

IPC: H04N5/357
Filed: 1993-09-09
Abstract: PURPOSE:To conduct the calibration of a measuring system including a light source without using a reference sample, and also, to prevent a measurement error from being generated due to aging of the measuring system. CONSTITUTION:In each chip, a main body sensor part 1 having a picture element 3, a read-out gate 4, a charge transfer part 5, an output circuit part 6, and input and output terminals 7, 8, and a reference sensor part 2 having a reference picture element 9 of size of a certain extent without being affected by a manufacturing fluctuation, a read-out gate 4a, an output circuit part 6a and an output terminal 8a are formed in advance. By setting a wafer in which such a solid- state image pickup element is formed to a measuring instrument, the sensitivity of the reference picture element 9 is measured. Since the reference picture element 9 is scarcely affected by a manufacturing fluctuation, its original sensitivity can be estimated. From this estimated value and a measured value, a correction coefficient is calculated. By measuring the sensitivity of the main body sensor part 1, and multiplying it by the correction coefficient, the sensitivity of the main body sensor part 1 is obtained.

Title: Musical tone generator
Inventor: DEJIMA TATSUYA
IPC: G10H7/08
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To embody a musical tone generator capable of generating the musical tones approximate to the musical tones of a natural musical instrument at a low cost with simple constitution by simulating the operation of the natural musical instrument. SOLUTION: A vibrator 8 corresponding to the shape and material of the musical instrument to be simulated is excited and the excitation response is measured. A resonance characteristic is led out in accordance with this excitation response and a filter constant meeting thereto is previously formed. When prescribed musical tone data W1 is generated according to a key touch operation, a DSP(digital signal processor) 10a subjects the musical tone data W1 to the filtering meeting the filter constant described above, thereby forming the musical tone data W2 of the timbre equivalent to the timbre of the musical instrument to be simulated.  As a result, the need for a logical arithmetic means of a high speed which is heretofore essential is eliminated and the operation of the natural musical instrument is simulated inexpensively with the extremely simple constitution, by which the musical tones approximate to the musical tones of the natural musical instrument are obtd.
