IPC: H01S5/00
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor laser which is excellent in single mode yield and both good and stable in characteristics, by a method wherein a current block is arranged so as to form a secondary grating. SOLUTION: Current block layers 10 are provided at a regular interval between an optical confinement layer 5 and a P-type clad layer 6, whereby a grating is formed. Furthermore, an N electrode 11 and a P electrode 12 are provided for the formation of a gain-coupled distribution feedback(GC-DFB) laser. In a GC-DFB laser, the current block layers 10 are each 240 nm wide and arranged at a regular interval of 480 nm. This structure functions as a secondary grating and is more uniform in characteristics than a primary grating, whereby a distributed feedback semiconductor laser excellent in single mode yield and both good and stable in characteristics can be obtained.

Title: Device for detecting shifting force of shift lever
Inventor: OZAWA SABUROU
IPC: G01L5/22
Filed: 1983-07-11
Abstract: PURPOSE:To separate the gripping force of a shift lever from shifting force and to detect accurately the shifting force at a real operating position by fitting a strain rod to the shift lever and covering the shift lever with a chucking cup with a space. CONSTITUTION:The distortion rod 11 to which a strain gauge 13 is stuck is screwed and fixed on the upper end part of the shift level 19 and the cylindrical chucking cup 12 having a gripping part 16 for operating the shift lever 19 is screwd and fixed on the upper part of the strain rod 11. Gripping force applied to the gripping part 16 by a gripping device 17 of a simulator is not transmitted to the strain rod 11 because the space is formed. When the gripping device 17 of the simulator operates the shift lever 19 and turns the shift lever 19 to a prescribed speed changing step, the operating force applied to the chucking cup 12 is transmitted to the strain rod 11. The distortion of the strain rod is detected by the strain gauge 13 and the operating force is measured by the simulator.

Abstract: PURPOSE: To improve the steering stability and the riding comfortability by detecting the relative dislocations between the upper and lower ends of the spring of a chassis thereby to adjusting the air pressure of an air suspension unit.  
     CONSTITUTION: A cylinder 10, which is equipped in its inside with light emitting diodes 21 and 22 and phototransistors 19 and 20, is attached through a bracket 14 to the swing arm at the wheel side, and a rod 13, which is equipped with a shielding plate 23 having a hole 24, is attached through a bracket 15 to a chassis frame 3, thus constituting a level sensor 1. This sensor 1 is connected with a control valve  32 which is interposed between an air source 35 and an air suspension unit 2.  Thus, if the upper and lower ends of the spring of the chassis are dislocated due to the weight difference, the variation in the load weights, the acceleration or deceleration, or the nose-down, the resultant dislocation is detected by the level sensor 1 so that the check valves 37W39 are opened and closed through solenoids SOL 1  and SOL 2 . Then, the air pressure of the air suspension unit 2 is adjusted so that the vehicle height is held as a constant level thereby to attain the desired object.

Title: Driving device using elastic material as driving source
Inventor: TAKAHASHI SHIGEMI
IPC: G03B9/08
Filed: 1989-05-18
Abstract: PURPOSE:To easily adjust the fitting position of a photointerrupter by stopping a motor at the timing where the set value of a timer means which is actuated by the inversion of the output of the photointerrupter is exceeded. CONSTITUTION:At the timing before a cam follower 15a moves onto a higher part 12a along a slanting surface 12c, the external edge part 15d of a mirror driving lever 15 moves off the optical path extending from a light emission part 22a to a light reception part 22b and the fitting position of the photointerrupter 22 is so adjusted that the output of the photointerrupter 22 goes up to an H level. A one-shot circuit 30 operates as a timer where the delay time from the rising of the output of the photointerrupter 22 from an L level to the H level up to the stopping of the motor 5 is set. Therefore, a margin corresponding to the set time of the timer is obtained from the detection timing of the photointerrupter 22 to the braking timing of the motor 5. Consequently, the fitting position of the photointerrupter 22 is easily adjusted.

Title: Oxygen gas sensor
Inventor: MOMIYAMA KIMIO
IPC: G01N27/407
Filed: 1981-08-12
Abstract: PURPOSE:To attain sensors with thermal shock resistance and good durability by a construction wherein electrodes are formed on a raw sheet containing stabilized ZrO2  powder, a resin bonding agent and a plasticizer, and thus formed two sheets are bonded  under high-temperature and high-pressure through a hollow raw sheet containing ZrO2  and then are sintered. CONSTITUTION:A raw sheet which contains ZrO2 powder stabilized with Y2O3, a bonding agent such as polyvinylbutyral, and a plasticizer such as polyethyleneglycol or  octylphthalate, is punched into a disc 23 formed with a fine hole 53 at its center. Dick- like platinum electrode 43 and lead portions 61 are formed on both sides of the disc 23  through screen printing. Thus obtained two discs 23 are superimposed on both sides of  an annular disc raw sheet 12 (made of the same material as the disc 23) having a  larger outer diameter than the disc 23, and then are sintered under high-temperature  after heating and pressure-bonding them. With one disc electrode 42 of thus obtained  sensor being as a sensing electrode, voltage is applied to the other disc electrode 41  through a feedback amplifier, thereby to measure O2 density. This sensor has good  thermal shock resistance, will never undergo separation at the bonded portions and has a prolonged service life. In addition, the measured results with good linearity can be  attained with respect to O2 density.

Title: Proportional solenoid type actuator
Inventor: UCHIYAMA MASAAKI
IPC: F16K31/06
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To reliably detect the stick of a spool when a spool is sticked when an actuator is used in a state to be connected to the spool of a regulation valve. SOLUTION: When an armature 3 is moved by a given amount, an annular groove 18 is formed in the outer peripheral part of the armature 3 in a manner to front on the tip part of a second cylinder part. When the current of a coil is increased to a value higher than a given valve and the annular groove 18 reaches a tip part, the generation of the magnetic flux (a magnetic flux entering an armature body 16 from a radial direction) of a magnetic passage A is reduced due to the presence of the annular groove 18. A magnetic field is relatively centralized to the magnetic passage B side to generate a high attraction force. The armature 3 is rapidly attracted to the bottom part 7 side and attracted to the bottom 7 and in this case, a current waveform is formed in a specific shape.  When the armature 3 is not sticked even when a coil is charged with a current exceeding a given value, a current waveform is not formed in a specific shape. By utilizing the above, it is detected whether the armature 3 and in turn the spool of a damping force regulation valve connected to the armature 3 is fixed.

Abstract: PURPOSE:To improve storage capacity and to make error management in the case of the occurrence of a fault in servo areas easier by specifying a relation between the number of data in a data area between the servo-areas and the length of a columnar direction when data is two-dimentionally arrayed. CONSTITUTION:The number of data which can be recorded between the servo- areas at an innermost periphery is set to (k). Zones Z1-Z4 are set so as to record data of the number of data, which corresponds to the number of data (k) and in which either (m) or the length (k) of data between the servo-areas is integral multiple of the other when data is two-dimentionally arrayed at (m) row and (n)column. As a light disk 1 is rotation-controlled with CAVs at respective zones Z1-Z4, the storage capacity can be turned larger without the occurrence of a crosstalk. As data of the number of data in which either (m) or the length (k) of data between the servo areas is integral multiple of the other when respective pieces of data are two-dimentionally arrayed at (m) row and (n) column is recorded between the servo-areas, error management in the case of the occurrence of the fault in the servo-area is facilitated.
