Title: Driver for piezoelectric transformer
Inventor: KUBO MASAKAZU
IPC: H05B41/392
Filed: 1995-06-06
Abstract: PURPOSE: To reduce power consumption and loss by a constitution wherein a high frequency circuit for driving a piezoelectric transformer comprises a link circuit, a phase regulating section, a shaping section, a delay circuit, and an output section comprising an MOSFET. CONSTITUTION: A drive current on the primary of a piezoelectric transformer flowing through a resistor provided on the source side of an MOSFET 10 at an output section is detected and fed to a link circuit 6 which produces a continuous sine wave. A phase regulating section 7 regulates the phase of a passing wave by varying the steepness and central frequency of resonance. A shaping section 8 converts an analog wave into a rectangular wave and inverts the phase. A delay circuit 9 delays the ON timing of MOSFET to produce a driving signal for the MOSFET. The MOSFET 10 at output section comprises two pairs of push-pull circuits, i.e., a pair of push-pull circuits where the drains of MOSFETs are connected and another pair of push-pull circuits for driving having reverse phase.

IPC: H04B14/04
Filed: 1981-10-31
Abstract: PURPOSE:To transmit additional information without decreasing transmission efficiency by positively utilizing the performance of an error correction code. CONSTITUTION:An analog signal (a) such as an audio signal is converted into a PCM data signal (b), and (n) PCM data signals are made into one unit block; and a synchronizing signal SYNC and a correction code are added to said block of a PCM signal data sequence (c) to obtain a signal sequence (e). Then, a PCM data signal (k) in this signal sequence (e) is replaced in a specific period by additional information ADD such as absolute address information to obtain a signal sequence (g), which is transmitted (or recorded). During regeneration, the additional information ADD is extracted from a received signal sequence (h) to obtain a signal sequence (i), and the replaced PCM data signal (k) in the string is restored by using the correction code to regenerate an original signal sequence (j), and each PCM data signal (k) is D/A-converted to obtain an analog signal l.

Title: Draining net for high frequency heating device
Inventor: KAWAI KAZUHIRO
IPC: F24C15/16
Filed: 1988-07-14
Abstract: PURPOSE:To improve convenience during the use and to reduce the occurrence of a hazard by a method wherein the width of a pair of protrusions, located in point-symmetrical manner, of the four protrusions formed on an outer peripheral frame of a draining net is increased to a value slightly higher than that of a holder, and the width of the one pair of the protrusions is set to a value obtained by adding 1/2 (the depth of a heating chamber -the depth of the draining net) to the width of the other one pair of the protrusions. CONSTITUTION:The protrusions of a draining net 1 by means of which the draining net 1 is placed and held on holders 5 situated to the side wall of a heating chamber 4 are formed. The width of a pair of protrusions 3A positioned in a point-symmetrical manner is set to a low value (a = c (holder size) + alpha), and the width of the other pair of protrusions 3B is set to a high value (b = a + beta (heating holder size d - a depth a of draining net) divided by 2), whereby no directional property in the longitudinal direction of the draining net is provided and handling is facilitated. The draining net can be positioned by means of the narrow protrusions 3A but when an outer peripheral frame 2 of the draining net is erroneously placed in a state to make contact with a rear wall 4B of the heating chamber, the narrow protrusions 3A are disengage from the holder 5. Meanwhile, since the wider protrusions 3B are supported to the holder, the support height on the right side of the draining net is widely differed from that on the left side of the draining net, end the draining net is mounted in a widely inclined state. Thus, it can be easily decided by a user also that the draining net is not in a normal mounting state.

Title: Speaker voice extractor
Inventor: YAMANAKA MAKOTO
IPC: G10L21/0208
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To extract only the voice of a speaker from sound receiving signals including the voice of the speaker and noise by providing a second sound receiver for receiving only the sound which is produced by vibration of a human body generated with vocalization of a speaker. SOLUTION: When a speaker vocalizes under a noisy environment, a first microphone 1 receives aural signals including the voice of a speaker and noise. Meanwhile, a second microphone 3 receives the sound produced by vibration of the eardrum of the speaker. A soundproof material prevents the environment noise from being received by the second microphone 3. The second microphone 3 thus receives the sound produced by the vibration of the eardrum of the speaker. A voice extraction part 6 extracts only such signals as having strong correlation with the output signals (b) of the second A/D converter 5, which converts the input signals of the second microphone 1, from among the output signals (a) of the first A/D converter 2 which converts the sound receiving signals of the first microphone 1. This constitution can extract only the voice of the speaker.

Title: Picture encoder and picture decoder
Inventor: EITO MINORU
IPC: H04N19/80
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To improve coding efficiency by using a nonlinear filter based on a gradation morphology arithmetic as the prestage filter of remainder encoding or a loop filter to apply for a predictive picture so as to save a code amount in an area which is not visually deteriorated much even without encoding remainder in a remainder picture. SOLUTION: A morphology remainder suppressing filter 104 processes the four steps of exchanging each pixel with the maximum value of eight neighboring pixels, next exchanging it with the minimum value of the eight neighboring pixels and additionally repeating the same exchanges. Thereby a peak value is suppressed in the state of an impulse so that the code amount is preferentially assigned to an area with visual deterioration even when a remainder signal is not encoded sufficiently by a low bit rate. The constitution of morphology loop filters 102 and 116 is completely the same as the morphology remainder suppressing filter 104 and though the predictive picture is provided with a peak, corrects it to a suppressed picture.

Title: Preparation of concrete of high strength
Inventor: NAKATO TSUYOSHI
IPC: B28C7/04
Filed: 1993-07-16
Abstract: PURPOSE:To make possible preparation of concrete of high strength whose the fludity and high-degree developing properties are improved sharply. CONSTITUTION:First, cement, water and a water reducing agent of high performance are kneaded to be made cement paste. Thereafter silica fumes and fine aggregate are put in. The fine aggregate is put in an appropriate time between the start of kneading of the cement, the water and the water reducing agent of high performance and the input of the silica fumes and the fine aggregate. Thereby the water reducing agent of high performance is adsorbed preferentially on the cement and the hydrate thereof, while it is hardly adsorbed on materials having large specific surface areas, such as the silica fumes and the fine aggregate. Therefore the water reducing agent of high performance acts very effectively on the dispersion of the cement and the hydrate thereof and thereby the fluidity of concrete at the time when it is fresh is improved.
