Title: Dc resistance welding equipment
Inventor: TAKANO FUMITOMO
IPC: H02M9/00
Filed: 1988-12-28
Abstract: PURPOSE:To diminish an electric power loss at the time of switching to almost zero by connecting a capacitor between the output side of an inverter and a primary coil of an output transformer and forming a resonance circuit by an inductance and the capacitor by viewing the output transformer side from the inverter. CONSTITUTION:In the inverter type DC resistance welding equipment, load of the inverter 24 constitutes the resonance circuit by the capacitor 28 and a coil 29 for resonance which supplies a welding current to a work. As a result, an inclination at the time of rising and falling of a current flowing between a collector and an emitter of a transistor 36a, etc., to constitute the inverter becomes gentle and the electric power loss generated at the time of switching is diminished to almost zero. The inverter type DC resistance welding equipment can been converted into high-frequency welding equipment and the output transformer 32 is miniaturized, etc. In addition, parallel connection of full-bridge type transistors is avoided by reduction of the electric power loss.

Title: A/d converter
Inventor: YAMAHA YOSHIRO
IPC: H03M1/38
Filed: 1992-12-14
Abstract: PURPOSE:To provide the A/D converter in which conversion resolution in all ranges of an input voltage is enhanced without improving the resolution of an output voltage in a built-in D/A converter. CONSTITUTION:Since a rough step voltage outputted from a 1st DAC (DACI) is converted equivalently to a very small step by changing an output voltage of a 2nd DAC (DAC2) by a very small step, the resolution of the entire AD converter is improved without improving the resolution of the 1st DAc (DAC1) and the linearity at conversion is improved.

Title: Speech recognition device
Inventor: FUNAMOTO TARO
IPC: G10L15/10
Filed: 1990-11-29
Abstract: PURPOSE:To improve the recognition rate at the time of reinputting speech by approximating the probability of reinput by the erroneous recognition of the previous time with the time from the end of the recognition to the reinput and weighting the data on the degree of similarity at the time of the previous recognition and adding this data to the data on the degree of similarity of the recognition of this time. CONSTITUTION:Voices are assumed to be uttered twice in the case of execution of speech recognition of 3 words of A, B, C. The 1st groups of the degree of similarity which are the output of the 2nd memory 4 in the recognition of the 1st time and the 2nd time are assumed to be a1, b1, c1 and a2, b2, c2. The 2nd groups of the degree of similarity which are the output of the 3rd memory 5 in the recognition of the 2nd time is, therefore, a1, b1, c1. The 4th groups of the degree of similarity which are the output of an addition circuit 7 of the 2nd time are eventually a2, b2+b1*K, c2+c1*K if the time from the end of the recognition of the 1st time before the start of the recognition of the 2nd time is assumed to be T, the weighting coefft. to be K and the result of the recognition of the 1st time to be A. The probability that the word A of the result of the recognition of the 1st time is outputted as the result of the recognition decreases and the information on the recognition of the 1st time is added to the words exclusive of A. The recognition rate is thus improved.

Title: Double-tube ozonizer
Inventor: ISHIOKA HISAMICHI
IPC: H01T23/00
Filed: 1993-12-28
Abstract: PURPOSE:To generate the concd. ozone proportional to an input power which is not decomposed by the temp. rise by closing the open end of a high-voltage electrode and forming the entire high-voltage electrode into a closed hollow tube. CONSTITUTION:This double-tube ozonizer is provided with a cylindrical grounded electrode 3 with a dielectric layer 4 attached firmly to its inner face and a cylindrical high-voltage electrode 5a concentrically set in the grounded electrode 3 with a discharge gap 6 in between. An AC voltage is impressed between both electrodes from an AC power source 7 to ozonize a raw gas 9 to generate ozone 10. The open end of the electrode 5a is welded with the same material or closed with a separately prepared sealant to form the entire electrode 5a into a closed hollow tube. Since the ozone 10 is not infiltrated into the electrode 5a, ozone is not decomposed by the heat of the electrode 5a, and the raw gas is not saturated with ozone at a low temp. The concn. of the generated ozone is linearly increased in proportion to the power density, and the concd. ozone is obtained with this small-sized device.

IPC: C09K3/00
Filed: 1988-12-29
Abstract: PURPOSE:To obtain an image forming material capable of generating heat by the absorption of light energy and forming a distinct three-dimensional picture image by using an absorbent for infrared rays consisting of a specified compound oxide. CONSTITUTION:The absorbent for infrared rays consists of a compound oxide consisting primarily of an oxide of Sn, Sb, or In. A red crayon is obtd. by mixing, for example, wax, pigment, a coloring material, and above-mentioned absorbent in a desired proportion, and the mixture is heated, mixed, and poured into a mold. A picture image is formed by hand with the obtd. crayon on a heat-expansive sheet provided with a heat expansive layer contg. heat-expansive minute spheres on one side of a sheet-shaped base material, and the picture image is exposed to light. Thus, the picture image part of the sheet rises and a red three-dimensional picture image is formed. Since clouding of color is caused scarcely when the absorbent is used, so a distinct three-dimensional picture image is obtd.
