Title: Correction of frequency generator
Inventor: OOHORA YASUNORI
IPC: H02P5/00
Filed: 1981-08-06
Abstract: PURPOSE:To correct an error to be generated by eccentricity or precision of a pattern, etc., of a frequency generator by a method wherein the quantity of variation of a sped signal when the generator is rotated in no loading condition is stored as an error of the frequency generator, and is used as a correction signal when loading operation is to be performed. CONSTITUTION:A motor 1 is rotated in no loading condition, and the rotating speed thereof is detected by the frequency generator 2 as frequency. The frequency signal thereof is converted into a voltage signal by a frequency speed signal converter 3, and the quantity of variation of output of the converter 3 at this time is stored in a wave form memory unit 4 as a component of error of a rotating speed detector. Then the motor 1 is rotated in loading condition, and the rotating speed signal thereof is detected by the frequency generator 2, the frequency speed signal converter 3. The speed signal thereof is converted into a speed signal containing no error by performing addition and substruction of the component of error stored in the wave form memory unit 4 by an operational amplifier 5.

Title: Semiconductor device
Inventor: HAGIMURA KAZUO
IPC: H01L21/331
Filed: 1981-08-10
Abstract: PURPOSE:To enhance the withstand voltage between the emitter and the collector of a semiconductor device and to prevent the leakage by forming the third diffused layer of high density on the surface of the first diffused layer as a base to surround the second layer as an emitter. CONSTITUTION:A P type diffused layer 2 becoming a base, an N type diffused layer 3 becoming an emitter, a passivation film 4 and base, emitter electrodes 51, 52 are formed on an N type silicon substrate 1 becoming a collector. In this case, a P type diffused layer 7 of high density is formed on the surface of the layer 2 to surround the layer 3. In this manner, even if an inverted layer 6 is formed on the surface of the low density region B of the layer 3, the inverted layer is not formed in the layer 7 of high density. Accordingly, since the layer 6 is discontinued in the course, even if the layer 3 is formed to extend to the low density region B of the layer 2, the withstand voltage between the emitter and the collector becomes high, thereby preventing the leakage.

Title: Semiconductor laser device
Inventor: SAGAWA MISUZU
IPC: H01S5/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent mode loss which is to be caused by mode conversion and stabilize a transverse mode, by using a structure wherein the stripe width of a region of high effective refractive index is changed in accordance with an exponential function along the resonator direction. SOLUTION: A semiconductor laser device has a stripe type region whose effective refractive index is higher than other parts, along the resonator direction. The width of the region of high effective refractive index is changed in accordance with an exponential function, along a resonator direction. That is, the width of the region of high effective refractive index is set to be smaller than or equal to 3.5μm on one end surface side of the resonator, and is set to be greater than or equal to 5μm on the other end surface side of the resonator. Since the stripe is wide in the front surface wherein high light density becomes problem, and the light spot is enlarged, light density is reduced. Since a back end surface whose light density is comparatively small is constituted as a narrow stripe, the transverse mode can be stabilized.  Therefore, a high output and high reliability laser is realized.
