Title: Melting type thermal transfer recording method
Inventor: SAITO HITOSHI
IPC: B41J2/345
Filed: 1991-03-15
Abstract: PURPOSE:To express multiple gradation without performing finely relative intermittent feeding of an ink film and a thermal head. CONSTITUTION:An ink film and a recording paper are fed intermittently by a unit feed quantity L substantially the same as the width of a heat generating element. At every intermittent feeding, the heating value of the heat generating element is controlled to 8 stages, and ink dots are recorded on one recording picture element by feeding intermittently 4 times. Temperature distribution of the heat generating element is irregular, having the highest parts at the centers of 2 electrodes. By controlling the heating value, 8 kinds of ink dots having different sizes are recorded. With the 8 kinds of ink dots and 4 kinds of recording areas, gradations having 32 stages are expressed.

IPC: F24F7/08
Filed: 1978-06-27
Abstract: PURPOSE: To raise the heat exchange ratio and decrease noises on a heat transfer surface, by placing  a heat exchanger symmetrically as to an intake and an exhaust passages so that the product of the acoustic impedances of the upstream parts of the intake and the exhaust passages at the heat exchanger is almost equal to that of acoustic impedances of the downstream parts of the intake and the exhaust passages.  
     CONSTITUTION: An outside intake port 16 and an outside exhaust port are opened through an outside wall 15. An inside exhaust port 19 and an inside intake port 20 are opened through an inside wall 18. The heat exchanger 21 is provided near the central part of the inside wall 18 symmetrically as to the intake passage 27 and the exhaust passage 28, which are symmetrically formed. As a result, the acoustic impedances Z 1 , Z 3 , Z 4 , Z 2  of the upstream and downstream parts 27a, 28a, 27b, 28b of the intake and the exhaust passages 27, 28 at the heat exchanger are related to one another as Z 1 .Z 4 ≈Z 3 .Z 2 . The invasion of noises through the heat exchanger is thus almost eliminated.

Title: Production of preformed compact containing whisker
IPC: C22C47/00
Filed: 1992-03-31
Abstract: PURPOSE:To obtain a high-strength preformed compact having sufficient shape retaining properties even if the whisker content is low by dehydrating and forming an aqueous slurry containing whiskers having an inorganic binder fixed to the surface and then drying the resultant compact.

Title: Antenna drive controller
Inventor: SAITO MASAKAZU
IPC: H02P29/00
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide an antenna drive controller capable of reducing power consumption by limiting a current to be supplied to a motor when the suppression of power consumption is required. SOLUTION: If service interruption is generated due to disaster or the like and drive by a battery or the like is started when a mode requiring the suppression of power consumption is set up, the current command value of a current to be supplied to a motor M for driving an antenna L is limited. When the supplied current command value exceeds a certain threshold, a current command value control part GC1 limits the current command value to the threshold. The limited current command value is converted into a driving current I for the motor M through a current compensation part GC. Thereby the driving current I supplied to the motor M is suppressed up to the limited threshold. Consequently power consumption required for the drive of the antenna L can be suppressed.

Title: Method of selecting organized channel
Inventor: ARUFUONSU AITSUENHEEFUAA
IPC: H04B7/26
Filed: 1987-04-01
Abstract: In prior cellular radio transmission systems a base radio station (BS) periodically transmits references identifying control channels associated with such base radio station, references identifying control channels of adjoining base stations, and references identifying a substitute control channel. The invention reduces the number of references which must be transmitted by a base station, which is of particular advantage in an integrated services cellular radio transmission system. A transmission channel of each base station is assigned as a simplex message transmission channel (COCH) in which a given base station (BS) transmits to the mobile stations (MS) information describing the structure of the control channels (CCH). Such information includes references (NC) to message transmission channels of adjoining base stations and references (CC) to one or more control channels assigned to the given base station. Since the message transmission channels are at a higher level in the hierarchy of references than the control channels, access by several different kinds of subscriber sets and different services can be provided by transmitting a relatively small number of references.

Abstract: PURPOSE:To provide a field emission type magnetic sensor having a high signal- noise ratio and high sensitivity. CONSTITUTION:An emitter 1 is grounded, and an AC signal 4 is applied in superposed state to the DC bias voltage 3 of VOP as voltage across the emitter 1 and a gate.

Filed: 1984-04-18
Abstract: PURPOSE:To attain the stable response by changing a demodulated color difference signal and a synthetic ratio of delay output of said color difference signal only for a period of a burst signal. CONSTITUTION:A reproduced low band converted carrier chrominance signal is supplied through an input terminal 30 and demodulated to two color difference signals by a demodulator 20. These signals are transmitted through comb-shaped filters 25 and 26 and modulated to carrier chrominance signals through a modulator 29. These color signals are delivered to an output terminal 31. The output of the filter 25 is sent to a burst gate 27, and an oscillator 33 is controlled by the output transmitted through an LPF28. Then the demodulator 20 is controlled for accurate demodulation. The filter 25 contains a delay line 21, amplifiers 22 and 23 and an adder 24. The amplification factors of both amplifiers 22 and 23 can be changed only in a burst period by a burst flag signal and supplied from a terminal 32 and showing the burst period. This prevents the unstable response.

Title: Digital data recording system

IPC: H04N5/92
Filed: 1987-03-31
Abstract: PURPOSE:To eliminate a need of new design of a signal format for digital data recording and reproducing by constituting digital data as a multilevel code sequence and recording each code of this sequence instead of a video signal at the same sample transmission speed as the video signal. CONSTITUTION:Digital data is constituted as a multilevel code sequence, and each code of this sequence is recorded as the signal of the level of the multilevel video signal instead of the video signal in frame or field units at the same sample transmission speed as the video signal. Consequently, digital data recording and video signal recording are arbitrarily selectively used in one frame or one field unit. Thus, it is unnecessary to newly design a signal format for digital data recording and reproducing, and only a simple circuit is added to a reproducing device to reproduce data.
