Title: Optical pickup device
Inventor: HASEGAWA YUICHI
IPC: G11B7/135
Filed: 1994-11-21
Abstract: PURPOSE: To provide an optical pickup device capable of correcting an astigmatic difference included in a semiconductor laser element without increasing the number of parts. CONSTITUTION: In an optical pickup device 3 having a collimator lens 6 converting a diffused laser beam L1, transmitted from a semiconductor laser element, into a parallel beam, the collimator lens is arranged tilted by a prescribed angle θ with respect to the direction orthogonal to an optical axis 13 so that the astigmatic difference included in the semiconductor laser element is compensated for by means of astigmatic aberration caused by the oblique arrangement. Consequently, a light spot scarecely having the astigmatic aberration is formed.

Title: Optical disk driving system
Inventor: KUDO TAKASHI
IPC: G11B33/14
Filed: 1994-11-20
Abstract: PURPOSE: To effectively utilize a filter and to decrease the excessive burden on a cooling fan by detecting an increase in the amt. of the dust sticking to a dustproof filter and changing this filter in an optimum period. CONSTITUTION: This optical disk driving system is provided with a transparent member 4 for sticking the dust to the periphery of the dustproof filter, a light emitting source LED 5 and PD 6 for detecting the transmitted light quantity of the member 4. This PD 6 applies the voltage output obtd. by converting the current corresponding to the received light quantity via an I-V converter 10 to a comparator 11. A reference voltage is applied from a comparing voltage generating means 12 to the comparator 11 which compares the voltage output with this reference voltage and applies an output signal to a controller 13 when the voltage output exceeds the reference value. The controller 13 sends a message to announce the exchange period to a host computer when the controller detects the output signal.  Namely, the comparator 11 outputs the output voltage of the converter 10 to the controller 13 when the output voltage exceeds the reference value and, therefore, the time for exchanging the filter is detected.

IPC: G01N21/41
Filed: 1989-11-30
Abstract: PURPOSE:To achieve a simultaneous detection of a first luminous flux and a second luminous flux after deflected with one detector by arranging a direction of deflection of a second luminous flux which is deflected by a refractive index difference between reference and sample fluids along a plane containing optical paths of the first luminous fluxes and the second luminous flux before deflected. CONSTITUTION:A cell 11 is arranged almost vertical to optical paths of a first luminous flux L1 which passes through a partition 14 dividing a reference fluid and a sample fluid and a second chamber 13b filled with the sample fluid and a second luminous flux L2 which passes through the second chamber 13b and a first chamber 13a filled with a reference fluid. At the same time, the partition 14 is so arranged as to be askew to the luminous flux L2. Here, the luminous flux L2 to be deflected corresponding to a refractive index difference between the reference and sample fluids is deflected along a plane containing optical paths of the luminous fluxes L1 and L2. Thus, one one-dimensional image sensor is arranged along the plane containing the optical paths of the luminous flux L1 and L2 and the luminous flux L1 and the luminous flux L2 after deflected can be detected with the detector simultaneously.

Title: Manufacture of lock bolt made of steel tube
Inventor: SUMIMOTO DAIGO
IPC: E21D20/00
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To reduce manufacturing cost by manufacturing a lock bolt made of a steel tube whose cross section is a cross having recessed parts in four directions and which has a shape intervals between the opening parts in the recessed parts of which are parallel or narrower as advancing toward the center axis of the bolt by using a die having the same cross-sectional shape as that of the lock bolt and by cold drawing a round tube. SOLUTION: The cross section of the lock bolt is the cross having recessed parts 6 in four directions. The relative relation of the cross is shifted 90 deg.C by 90 deg.C from the center axis, but error within ±10 deg. is justified. When the error is larger than this value, bend is generated at the time of manufacture. Opposite sides 7 with which the recessed parts 6 are formedare parallel or intervals between them are made narrower as approaching the center axis. When the sides are spreaded, the tip of the drawing die becomes bigger and the tube is not worked into a prescribed shape by single drawing. The diameter in the outermost peripheral part of the lock bolt is smaller than that of the round tube before working and made smaller than the diameter of a hole drilled on base rock.

Title: Air-fuel ratio controller of internal combustion engine
Inventor: ONO KENICHI
IPC: F02D41/14
Filed: 1993-12-13
Abstract: PURPOSE:To improve control reliability by forcibly executing learning at the time of appearance of a specified condition, regardless of output of an oxygen sensor on the downstream side, when output of the oxygen sensor on the downstream side of a three-way catalyst allows to learn a control coefficient at reversing timing. CONSTITUTION:Oxygen sensors 19 are provided respectively on upstream and downstream sides of a three-way catalyst equipped on the exhaust pipe 7 of an internal combustion engine 1, and a control coefficient necessary for air-fuel ratio control is calculated by a control constant calculation means in response to the output of the downstream side sensor 119. The calculated control constant is learnt by a learning means by a timing in which the output of the downstream side sensor 119 is reversed between rich and lean conditions. The air-fuel ratio control is executed by the air-fuel ratio control means based on the output of the upstream sides sensor 19 and the learnt control constant. In this case, learning is forcibly executed by a forcible learning means at the time of appearance of a specified condition, even if reverse is not generated in the output of the downstream side sensor 119, and thereby such a problem that a control cycle is long and responsiveness is slow is solved.

Title: Huffman decoding circuit
Inventor: ASANO MASANARI
IPC: H03M7/42
Filed: 1994-12-15
Abstract: PURPOSE: To quickly decode Huffman code data to generate decoded data by forming code data having fixed bit length and inputting the formed data to a decoding means. CONSTITUTION: A code data entering part 1 enters code data IN1 supplied from the external and forms code data IN2 with fixed bit length. A Huffman decoding lookup table 2 receives the code data IN2 and outputs decoded data OUT1 corresponding to a code of upper bits and a code size (n). The entering part 1 omits upper bit data only by the bits of the code size (n) outputted from the table 2, enters code data IN1 newly supplied from the external instead of the omitted data, forms the code data IN2 of the fixed bit length and supplies the data IN2 to the table 2 to repeat the processing. Thereby the table 2 outputs the decoded data OUT1 immediately after the input of code data IN2 regardless of the bit length of the code.

Abstract: PROBLEM TO BE SOLVED: To prevent misalignment after adjustment of a laser beam oscillator. SOLUTION: Air bags provided within a central gap defined when upper and lower cavities 2 and 3 are accommodated in a main body 1b of an acrylic container 1. The air bags 7 act to absorb vibrations caused by the vaporization and expansion of cooling water which absorbed part of light from flash lamps 6. The lower cavity 3 is formed as divided into first to third lower cavity pieces 3a to 3c, so that, upon its maintenance, the lower cavity 3 can be removed without need for removing a laser rod 5 and the flash lamps 6. As a result, it can be prevented that internal vibrations cause already-adjusted alignment to get out of adjustment and also the already-adjusted alignment to get out of adjustment upon maintenance such as exchange of the cavities 2 and 3.
