Title: Rhythm control system
Inventor: SAKAYORI TETSUYA
IPC: G10L13/02
Filed: 1988-06-24
Abstract: PURPOSE:To generate a very natural rhythm pattern by inputting a qualitative parameter to an input unit and predicting a quantity constituting rhythm by a neutral net. CONSTITUTION:A qualitative parameter extraction part 1 extracts the qualitative parameter (ai) (1<=i<=m) which is considered to affect phoneme continuance from an input character string. This is inputted to the neutral net 2, the output of the input unit is inputted to an output unit through plural intermediate units 2 to obtain an output value by the state transition function of the output unit, and a linear conversion part 3 performs linear conversion to obtain the phoneme continuance. Thus, various qualitative parameters which are considered to affect the quantity constituting the rhythm are inputted and the rhythm is controlled by the neutral net by back propagation outputting the quantity constituting the rhythm. Consequently, a very natural synthetic voice is obtained.

Title: Tape speed discriminator for magnetic recording and reproducing unit
Inventor: NIWA KIICHI
IPC: H04N5/7826
Filed: 1978-12-19
Abstract: PURPOSE: To reproduce several kinds of TV systems, by easily matching the tape speed at recording and reproduction, by comparing the control signal frequency at recording with the reference frequency produced in VTR at reproduction to obtain discrimination signal.  
     CONSTITUTION: The unit consists of the reference oscillator 1 providing the diapason 1a for the first tape speed VP and diapason 1b for second tape speed VN, speed control circuit controlling the servo system, and frequency division circuit 3. Taking the frequency of oscillator 1 as 1867Hz when the speed VP is 28.33mm/s and as 2663Hz when the speed VN is 38.35mm/s, the frequencies are respectively 28.04 and 32.87Hz with 1/81 frequency division at the circuit 3. Thus, the control signal frequency recorded with the first system is higher than the frequency at the circuit 3 when reproduced as the speed VP, VN. Conversely, the control frequency recorded at the speed VN is always lower than the frequency of the circuit 3 when reproduced in VP or VN. With this system, the recording system can be discriminated by comparing the frequency at the circuit 3 with the reproduced control frequency.

Title: Formation of contact hole
Inventor: MIMURA YOSHIAKI
IPC: H01L21/30
Filed: 1988-06-25
Abstract: PURPOSE:To make a minute contact hole simply and stably by a method wherein, while a change in a physical property of a resist material is utilized, a diameter of the contact hole is controlled precisely and an angle of inclination of a resist profile is controlled precisely. CONSTITUTION:When a resist material is heated to a softening point or higher, a resist pattern is plastic-deformed suddenly; in this state, it is extremely difficult to precisely control a shape of the resist pattern. Therefore, before the resist pattern is heated to the softening point or higher, it is irradiated in advance with ultraviolet rays and an optically hardened film with a thickness of about 0.2mum is formed on its surface layer. Thereby, a plastic deformation is caused gradually by a high-temperature heating operation after that; its shape can be controlled accurately with high reproducibility. Thereby, a minute hole diameter and an arbitrary taper etching shape which are required for the manufacture of a large-scale LSI can be formed with good controllability in a simple single-layer resist process.

Title: Optical information recording medium
Inventor: ONO EIJI
IPC: G11B7/24
Filed: 1992-06-17
Abstract: PURPOSE:To increase the quantity of reflected light at the time of reproducing and to improve recording density by setting the reflectivity of the reflected film in the pits of the recessed parts of a base body higher than the reflectivity in the circumferential parts. CONSTITUTION:Ruggedness is formed on the substrate 7 and the recessed parts are formed as the recording pits 9. The reflected film 8 consisting of Al, etc., and an over coat 4 are laminated on the substrate 7. The reflected film 8 in the pits 9 is formed thicker than in the circumferential parts so that the reflectivity of the reflected film is increased in these parts. as a result, pit information is well reproduced even where the spot light for reproducing is made small at the time of reproducing the pits by the reproducing light. The optical information recording medium which can be increased in the recording density and is exclusively used for neproduction is thus obtd.

Title: Sliding resin material
Inventor: SUZUKI OSAMU
IPC: C10M107/20
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a sliding resin material having excellent sliding properties, by mixing a thermoplastic resin with graphite. CONSTITUTION:A thermoplastic resin is mixed with graphite. The thermoplastic resin used is preferably polyphenylene oxide, polybutylene phthalate, polyamide, polycarbonate, or polyacetal, and polyacetal is particularly preferable. A copolymer type polyacetal is preferable to a homopolymer type. Although graphite can impart antistatic property or electric conductivity to a sliding material because its specific volume resistance is at most 10<-10> time larger than that of the resin material, an amount of 35wt% or above is necessary to impart marked electrical conductivity. A fluorocarbon resin is a component having an effect of further improving the sliding properties improved by graphite and a lubricating oil.

Title: Distillating method in dry cleaner
Inventor: HAGIWARA HARUO
IPC: D06F43/08
Filed: 1988-06-28
Abstract: PURPOSE:To prevent distilling speed from reduction by detecting continuously evaporated gas temperature in a distiller with a temperature sensor to change over a heat source in the distiller from low temperature heating to high temperature one when the detected temperature reaches a predetermined temperature which may cause reduction of the distilling speed. CONSTITUTION:In a dry cleaner capable of holding simultaneously at least two kinds of organic solvents soluble into each other and having different boiling points such as perchloroethylene and CFC-R113, the mixed solvent is subjected fractional distillation and separation through two-step heating at high and low temperature. Then, evaporated gas temperature in a distiller 150 is detected continuously by a temperature sensor 32. Further, when the detected temperature reaches a predetermined temperature to reduce the distillation speed, a heat source of the distiller 150 is changed over from low temperature heating to high temperature one. Thus, the distillation speed can be prevented from excessive reduction due to the rise of boiling point in the distillation, and the distillation can be performed in the shortest time without any break-out of abrupt boiling accidents.

Abstract: PURPOSE:To attain stable operation even at a low talking by constituting the electronic circuit so as to attain constant voltage type loading characteristics in order to ensure a minimum voltage for a transmission and reception amplifier in the inside of the electronic circuit at a low current condition. CONSTITUTION:A voltage V2 across a reference resistor R3 and a voltage V3 across a constant voltage diode D3 are fed respectively to an inverting input of an operational amplifier 1 via diodes D1, D2 and a resistor R5. Thus, the operational amplifier 1 acts that a voltage V1 dividing a trunk line terminal voltage VL by resistors R1, R2 is equal to any higher voltage of the voltage V2 or the constant voltage V3 across the resistor R3. On the other hand, when the talking current IL is decreased from a value, the relation of V2<V3 is obtained, and the VL-IL characteristic in this case is expressed as VL=V3(R1+R2)/R2. Since the voltage V3 is a prescribed value independently of the current IL, the voltage VL is constant independently of the current IL.
