Filed: 1983-08-11
Abstract: PURPOSE:To improve both mechanical and optical performances and also to attain a thin and small structure for an optical head by reflecting the light upward at a place right under an objective lens and leading the reflected light to a recording medium from a light source set in parallel to an objective lens arm provided to an actuator. CONSTITUTION:The light given from a semiconductor laser 21 is made incident on a polarizing prism 23 in the form of parallel luminous fluxes through a lens 22 to transmit through a polarizing film 24 and then reflected totally and rectangularly by a prism 25. This reflected light is led to an objective lens 27 through a lambda/4 plate 26 and formed into a light spot on an optical disk. The light reflected by the optical disk travels along the same optical path as a going path up to the prism 23 to be reflected by the film 24 and is reflected again on an optical surface 28a of a critical angle prism 28 to be made incident on a photodetector 29. The detector 29 contains four photodetecting areas 29a-29d which are divided half in radial and tangential directions of the optical disk respectively. Then a data signal, a focus error signal and a radial error signal are obtained from these outputs of areas 29a-29d.

Filed: 1986-06-25
Abstract: PURPOSE:To attain the tracking without using an actuator by using an optical pickup comprising a semiconductor laser and a converging grating so as to adjust the injection current of the semiconductor laser and to change the diffraction angle of the converging grating thereby applying tracking. CONSTITUTION:A laser light 5 emitted from the semiconductor laser 2 goes out of a converging pickup via the converging grating 4 and collected into a spot S1 on the surface of an optical disk 7, but the spot S1 is placed at a position deviated from the recording track of the optical disk 7 to required the tracking for the correction.

Since the tracking is applied by adjusting the injection current to the semiconductor laser 2 without using any mechanical actuator in this way, the optical pickup with small size and high speed is obtained.

Title: Word voice recognizing method
Inventor: IRUMANO TAKAO
IPC: G10L15/06
Filed: 1983-08-13
Abstract: PURPOSE:To maintain a high recognition rate by correcting a value of tolerance weight in the direction for reducing a difference between the first rank of a weighted similarity degree and a weighted similarity degree in a dictionary item of an input word, whenever an erroneous recognition is generated, and using its value in the next time and thereafter. CONSTITUTION:When a word A is at the first rank of a similarity degree, for instance, if a value of tolerance weight applied to a similarity degree of a word B is an (n) point, and a result of work recognition is A against an input of B, the previous value of tolerance weight is corrected automatically to (n)+(m) points. Also, in case when a correct recognition result is obtained against an input of A and B, a value of tolerance weight remains as it is. On the other hand, in case when the result of word recognition becomes B against the input of A, on the contrary, the value of tolerance weight is corrected to (n)-(m). By continuing it, the value of tolerance weight is converged to a value by which a recognition rate as a whole becomes the highest.

IPC: H03K5/15
Filed: 1977-12-09
Abstract: PURPOSE: To obtain the simplified gate pulse generating circuit with the combination of the counter circuit and the shift register.  
     CONSTITUTION: The gate circuit G1 connected to the -Q output terminal of FF is conductive when the count value of binary counter B reaches the set value. The gate pulse GP 1  is given to FF and shift register S via the OR circuit OR, and the register S delivers conduction enable signal to the gate circuit G2 from the output of 1st bit. Since the pulse GP 1  is given also to the clock pulse terminal CK of FF, the signal disabling the conduction of the circuit G1 is given from the -Q terminal of FF. When the count of the binary counter B is progressed and the gate circuit G2 is conductive, the pulse GP 2  is transmitted and it is given to the register S via the circuit OR, transferring the output signal of the register S from 1st bit to 2nd bit. Every time when the gate pulse is made, the register S renews the step and FF is reset when the pulse GP m  is transmitted.

Abstract: PURPOSE:To enable a wheel to be rotated in running even when air within a tire is emptied by arranging a tire support wheel between the both side flanges of a rim, and concurrently arranging a directional element having a specified air resistance exerted between an air chamber and the inside of the tire. CONSTITUTION:A hollow tread support wheel 3 the diameter of which is larger than the outer diameter of respective flanges 2, is arranged between the respective flanges 2 positioned at the both sides of a rim 1. And a directional element 6 is arranged between the inside of an air chamber 4 formed in the tread support wheel 3 and the inside of a tire 5. In this case, the directional element 6 is set up in such a way as to provide little resistance when air flows from the inside of the tire 5 to the inside of the air chamber 4, and to provide great resistance when air flows from the inside of the air chamber 4 to the inside of the tire 5 on the contrary. This constitution thereby enables the tread support wheel 3 to support the tread of the tire 5 even when air within the tire 5 is emptied, thereby making it possible to allow the air resistance of the directional element 6 to damp the shock acting on the tire 5.
