Title: Gamma correction circuit
Inventor: KOKUBO YUJI
IPC: H03G11/08
Filed: 1994-06-17
Abstract: PURPOSE:To conduct gamma correction with high accuracy without deteriorating the S/N by adding the output of a nonlinear amplifier means whose amplification factor is adjusted to the output of a linear amplifier means whose amplification factor is adjusted. CONSTITUTION:Since the resistance of a collector resistor R2 of a transistor(TR) Q1 of an inversion compression section 111 is selected the same as that of a collector resistor of a TR Q2, a signal given to a terminal 11 is compressed in a ratio of R2/R1. Suppose that the sum of emitter currents of TRs Q3, Q4 of a nonlinear amplifier section is constant, a collector current I4 of a TR Q4 is a curve changed exponentially with respect to a base voltage (VR3-VR4). Then the TR Q4 amplifies the voltage nonlinearly and provides an output to a summing resistor R4. A linear amplifier section 13 is a differential amplifier comprising TRs Q5, Q6 and amplifies a difference between an input signal and a bias voltage V2 with an amplification factor of R4/R5 and provides an output to a summing resistor R4. Thus, the nonlinear region is obtained for a prescribed signal voltage or below and the linear region is obtained smoothly for a prescribed signal voltage or over and gamma correction is executed with high accuracy.

IPC: F01N3/10
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To facilitate the assembly work of the exhaust pipe of a series type engine for an automobile, and provide structure having compatibility. SOLUTION: A flange 12 is arranged at the exhaust port of an exhaust manifold 10 made of a plate and a flange 15 is arranged at the inlet opening part 4a of an exhaust pipe 4 juxtaposed with a manifold converter on the inlet side. The bolt holes 12a for fastening of the flange 12 in a matched state between the flanges 12 and 15 are formed in uniformly divided three spots containing a spot seen from above between the ports 14. The thermal efficiency of a product material is high, weight is reduced, and size is decreased. The seal area of a joint between the two flanges 12 and 15 is reduced, and even when fastening is effected in three spots, sufficient sealing ability is ensured. Further, since a nut 9 is fastened from above equipment, a burden on a worker is relieved.

Abstract: PURPOSE: To avoid reduction of the thickness of a protecting film of a semiconductor device at the upper end of its groove by obliquely cutting off the upside wall of the groove when coating the protecting film on the exposed pn junction by perforating the groove at a semiconductor substrate.  
     CONSTITUTION: A p-type layer 2 is diffised on an n-type semiconductor substrate 1 to thereby produce a pn junction thereon, and the surface is coated by a SiO 2  film 3. Then, openings are provided at predetermined regions on the film 3 and etched thereat to thereby form grooves 4 perforated into the substrate 1. Thereafter, the cutting blade 10 of a dicing machine makes contact with both walls stood on both sides of the groove 4 to thereby obliquely remove the boundary between the surface of the diffused layer 2 and the groove 4 to thus form an oblique portion 9 thereat. At this time the angle α is set to 30W60° so that the end of the cutting blade 10 may not reach the pn junction. When the upside walls of the groove 4 are formed obtuse, no loss occurs at glass film 6 coated thereon nor etching liquid is immersed thereinto at the later etching step so as to thereby improve the reliability of the semiconductor device.

Abstract: PURPOSE:To make the opening-closing operation of a cover body sure by providing the cover body to the opening of a case for a tape cassette, and energizing this cover body to a closed state by means of an energizing spring. CONSTITUTION:When a cassette 1 is inserted with the horizontally long opening 13 at its front as a leading end into a cassette holder 28, the leading end of a leaf spring 30b abuts on a cover 15b and is accepted into a recessed part 20b where it is inserted up to the solid line position of the figure. When the cassette 1 in this state is further inserted into the holer, it turns out that the cover 15b is pushed relatively by the leaf spring 30b in the recessed part 20b. Since this recessed part 20b is disposed on the lefter side of the figure than the axial pin 18b pivotally supporting the cover 15b, the cover 15b receives rotating force in the counter clockwise direction around the axial pin 18b by overcoming the force of a return spring 19b, and the cover 15b is thereby opened.

Title: Intonation control system for voice synthesizer
Inventor: SAWADA YOSHIMASA
IPC: G10L13/00
Filed: 1989-05-30
Abstract: PURPOSE:To obtain proper intonation by controlling a pitch time constant with control data according with the accent type and the accent change direction. CONSTITUTION:Intonation is determined in a sentence processing part 2 in the same manner as conventional, and the accent type is determined in an accent processing part 3. Accent change point and direction of each accent type are discriminated at the time of determining the accent type in the accent processing part 3 with a word or a clause as the unit. With respect to a coefficient of the pitch time constant according with the accent type, the coefficient at the accent change point is determined in accordance with the accent type and the accent direction by table data. Consequently, intonation different by word or syllable is obtained with the pitch time constant of phonemes or syllables fixed. Thus, a synthesized voice of natural intonation approximating the human voice is obtained.
