Title: Butterfly operation device and inverse discrete cosine transformer
Inventor: OBAYASHI YOSHIMASA
IPC: H04N19/60
Filed: 1995-04-28
Abstract: PURPOSE: To provide the butterfly operation device and the inverse discrete cosine transformer which perform decoding in a short time. CONSTITUTION: x0 and x1 are dual input data, and y0 and y1 are dual output data, and c00 and c01 are butterfly operation coefficients of x0, and c10 and c11 are those of x1. A zero discrimination part 20 discriminates whether dual input data is zero or not and reports the result to each part. A multiplication input switching part 21 outputs the dual input in the case of x0=0 and x1=0 but sends it to a multiplication part 22 in the other case. An addition input switching part 23 outputs the output of the multiplication part 22 in the case of x0≠0 and x1=0 or x0=0 and x1≠0 and sends it to an addition part 24 in the case of x0≠0 and x1≠0.  The multiplication part 22 operates x0×c00→y0 and x0×c01→y1 in the case of x0≠0 and x1=0 and operates x1×c10→y0 and x1×c11→y1 in the case of x0≠0 and x1≠0 and operates x0×c00→d00, x0×c01→d01, x1×c10→d10, and x1×c11→d11 in the other case. The addition part 24 operates d00+d10→y0 and d10+d11→y1.

Title: Information write and read system for magnetic medium
Inventor: SASAKI HAJIME
IPC: G11B5/09
Filed: 1985-05-20
Abstract: PURPOSE:To attain the tracking of a magnetic head with sufficient accuracy without causing a waveform distortion in a servo signal even during a period when a write current is supplied to a magnetic head by using a magnetic head assembly having one floating slider provided with two magnetic heads. CONSTITUTION:In writing a data pattern 5 to a data track 4, a write data DW is inputted to a data write/read amplifier 8a to supply a write current IW to a magnetic head 7a. In this case, a read signal VHb obtained from a magnetic head 7b is not affected by the write current IW fed to the magnetic head 7a because the magnetic heads 7a, 7b are provided independently on a floating slider 11. Thus, a servo signal Vs obtained from a servo signal band-pass filter 10 when the write current IW is fed to the magnetic head 7a is a signal with sufficient quality without waveform distortion, equal to the signal when no write current is supplied.

Title: Floating valve utilizing difference caused by directional change in fluid resistance
Inventor: TANAKA HIROMI
IPC: F16K15/06
Filed: 1986-05-10
Abstract: PURPOSE:To enable extremely weak force to make perfect valve sealing by acting fluid resistance onto a valve so that a valve axis may be settled in a direction suitable for a valve seat. CONSTITUTION:A valve seat surface 2 is usually formed in axial symmetry to its axis 3, therefore the valve seat fitting surface 2 of a floating valve 1 must be expected to be axially symmetric and coincide with the valve seat surface 2. Since the triangular or a fez-shaped floating valve 1 is locked in a stationary valve body 10, when buoyancy or residual gravity causes the said valve 1 to begin a rise or a fall relatively to liquid, the said valve 1 begins to rotate so that fluid resistance may become steady and minimum, and then rises or falls relatively to the liquid with its top turning upward or downward. Therefore, the said floating valve 1 can always make the valve seat fitting surface 2' suitable for the valve seat 2 coincide with the valve seat 2 in its fitting direction.

Title: Method of cleaning bath furnace having hot water feeder
Inventor: ONODERA SHUICHI
IPC: F24H1/46
Filed: 1990-04-25
Abstract: PURPOSE:To perform an efficient sterikization of a bath furnace and washing away of hot water mud by a method wherein a valve enabling feeding of hot water and another valve enabling feeding of a large amount of flow rate are disposed at an upstream side of a heat exchanger at the bath furnace side. CONSTITUTION:An electric valve 26 is disposed at an upstream side of a heat exchanger 7 at a bath side. When a washing button 22c of a remote controller 22 is pressed, the electric valve 26 is adjusted to be closed and then hot water of 60 deg.C to 8O deg.C can be attained. A temperature of fed-out hot water is detected by a temperature sensor 24a and the electric valve 26 is once fully opened after getting hot water set to a specified time required for performing sterilization. The temperature of hot water fed is not related to the temperature of hot water set in the remote controller 22 and is lower than the hot water temperature set in the remote controller. With such an arrangement, the bath furnace is distilled with fed hot water at the beginning of operation and at the same time hot water mud adhered to and accumulated in the bath furnace is floated up, and then a high flow rate of hot water is released to enable the hot water mud adhered to the inside part of the furnace to be washed away.

Filed: 1990-04-25
Abstract: PURPOSE:To make it possible to elongate the continuous operating time and to make it possible to expand the control range of humidity by connecting a cross-fin type evaporator and a bare-tube type evaporator in parallel so that the evaporators can be switched. CONSTITUTION:A cross-fin type evaportor 19 and a bare-tube type evaporator 20 are connected in parallel in a switching type so that the evaporators are switched with solenoid valves 18a and 18b. At the time of ordinary temperature and humidity control, moisture removal and cooling are performed by the cross- fin type evaporator 19. In the low temperature and humidity control operation using the bare-tube evaporator 20 as the special evaporator, the icing of condensed dew water and clogging of the evaporator are prevented, and the continuous operation for a long time can be performed. In the low humidity control operation, the difference between the temperature of the surface of the bare-tube type heat exchanger pipe and the temperature of passing air is large. Dehumidifying performance is increased in comparison with a conventional cross-fin type apparatus. The humidity control range is increased in comparison with the conventional apparatus, and the excellent operation can be achieved.

Abstract: PURPOSE:To perform energy conservation under the control of humidity of an environmental tester having a humidifier. CONSTITUTION:An air conditioning room 2 has a blower 3, a heater 4, an evaporator 5 of a refrigerator, and a humidifier 6. An inlet of a testing chamber 1 has a temperature sensor 7 and a humidity sensor 8. Part of the air in the chamber 1 is passed through a dehumidifier 12 having a rotor 121 to be driven by a motor 122 to form a bypass dehumidifying line. Detection signals of the temperature and humidity sensors are introduced to a temperature and humidity regulator 14, which generate heating and humidifying outputs to control temperature and humidity of the air to be fed to the chamber 1.
