Title: Method of sintering refractory material
Inventor: SAIDA JUNJI
IPC: B22F3/14
Filed: 1994-09-16
Abstract: PURPOSE: To utilize the skin effect occurring when high-frequency high electric current is supplied at high voltage and to sinter an Al-containing difficultly sinterable raw material in a short time. CONSTITUTION: An AC electric current of >=500 V maximum voltage, >=1 kA/cm<2> maximum electric current, and >=1 kHz frequency is supplied to a powder of heat resistant material containing 5 to 95 atomic % Al so that total electrification time becomes 50×10<-6> to 500×10<-3> sec. As the elements other than Al, contained in the sintering raw material, Nb, Ti, Ni, or the like, can be cited. Because the Joule heat effective in the mutual bonding of powder particles is generated solely at the surface of the particles, the residual stress of the resultant sintered body due to thermal hysteresis can be reduced and the sintered body of high strength and high density can be manufactured in high efficiency.

Abstract: PURPOSE:To obtain a quantum-wire structure element having a structure wherein a quantum wire is produced without being changed by the purity of a GaAs film, by constructing the element so that a potential in relation to a conduction band electron be the minimum at a position in the central part of a well layer. CONSTITUTION:Carriers in the vertical direction are confined by using a double heterostructure which is formed by holding a semiconductor well layer 11 from the opposite surfaces by P-or N-type semiconductor barrier layers 12. On the other hand, carriers in the horizontal direction are confined by a construction wherein the opposite lateral sides of the double heterostructure are held by P-or N-type semiconductor barrier layers 13 between. Electrons supplied from the barrier layers 12 are accumulated on interfaces on the well side between the barrier layers 12 and the well layer 11 and a two-dimensional electron gas is formed. Besides, a potential in the horizontal direction becomes minimum in relation to conduction band electrons in the vicinity of the central parts of the well layer 11 and the barrier layers 12. According to this constitution, a quantum wire structure element having a structure wherein a quantum thin wire is produced without being changed by the purity of a GaAs film can be obtained.

IPC: G06K19/06
Filed: 1991-09-27
Abstract: PURPOSE:To automatically overcome a faulty contact by inserting an optical card to a shuttle and driving it for a fixed time even though a contact switch malfunctions by any chance. CONSTITUTION:First, set zero the count value of the error counter located in a controller 10 and rotate a motor 9 in an ejection direction. When a sensor 12 detects an optical card 5, then set an ejection time in a timer 17. And, if a sensor 13 does not detect the card 5, the sensor 13 is in its normal condition. Stop the motor 9, should the timer 17 passes the ejection time and stop the system if the error count is not a prescribed value. When the sensor 13 detects the card 5, check whether the error count has reached the prescribed value or not and add one to the count if the count has not reached the value. Next, set an insertion time in the timer 17 and rotate the motor 9 until the insertion time passes. Having this arrangement, a faulty contact is overcome even though the switch has by any chance malfunctioned.

Title: Semiconductor device
Inventor: KUWAZAWA ATSUSHI
IPC: H01L21/822
Filed: 1988-10-03
Abstract: PURPOSE:To make input/output bidirectional signals transmit to external and internal cells and prevent the generation of a short circuit current by providing the device with an asynchronous system latch function block at the preceding stage of the function block which transmits the input/output bidirectional signals to the internal cell. CONSTITUTION:This device comprises the following blocks: an output block 5 which is inputted by an internal cell output signal 2 and outputs to a shared input/output external terminal; an asynchronous system latch function block 7 which is inputted by a signal 3 of the shared input/output external terminal; and an internal cell transmission block 6 which is inputted by the output of the above latch function block 7 and transmits the above output to an internal cell. The asynchronous system latch function block 7 may hold, as occasion demands, a stable signal of a shared input/output terminal part. Even though there is a state that signals from the outside are not inputted irrespective of the fact that shared input/output cells are in an inputted state, signals generated immediately before coming to the above mentioned state that the signals from the outside are not inputted are transmitted to both external and internal cell. A short circuit current which flows by inputting unstable signals is thus prevented.

Title: Sio2-covered plastic film and manufacture thereof
Inventor: KOKUBO MASAHIRO
IPC: C08J7/06
Filed: 1994-10-14
Abstract: PURPOSE: To obtain a SiO2 -covered plastic film having gas barrier properties and wear resistance by a method wherein a SiO2 film, which contains a specified value by atomic percentage of nitrogen obtained by converting polysilazane to ceramic, is formed on one side of the plastic film. CONSTITUTION: Coating composition, which is prepared by melting polysilazane in solvent, is applied by gravure coating method or the like on at least one side of plastic film and, after that, is subjected to heating treatment under the temperature, which does not mar the plastic film. In the heat treatment under the above-mentioned temperature, since the conversion to ceramic is imperfect in the film, through the heat treatment in water vapor atmosphere or the immersion in catalyzer-containing distilled water or both the heat treatment and the immersion, the formation of dense film substantially made of SiO2 becomes possible. Since the SiO2 film comes from the polysilazane, the film contains 0.05-5% of nitrogen by atomic percentage. If the nitrogen content is more than 5%, insufficient conversion of the film to ceramic results.  On the other hand, the nitrogen content less than 0.05% is hard to realize.

Title: Drive controller and drive control method
Inventor: KAMEYAMA SHIGERU
IPC: H02P8/12
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To suppress noise and vibration during 1 step drive by switching excitation pattern of each excitation phase, in response to the number of revolutions of a rotor. SOLUTION: When drive start of a stepping motor 501 is designated, data having a predetermined pattern from a central processing unit(CPU) are output, and the data are input to excitation signal input terminals 401a to 401d for drive. Then, an IC 401 for drive switches the excitation phase of the stepping motor 501 based on the data, and furthermore the current is controlled so as to become a preset current value. In this way, the rotor drives 1 step at the time when the torque generated by the motor exceeds the load torque, and no excessive torque is applied so that the response of the rotor does not become vibrative, thereby suppressing generation of noise or vibrations.

Title: Electric refrigerator
Inventor: FUJIWARA MICHIYUKI
IPC: F25D23/02
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of the temperature of the internal part of an electric refrigerator due to release of an opening and closing door and to reduce power consumption. SOLUTION: A freezer or a cold storage chamber arranged at a cold storage chamber body 2 or an opening and closing door 3 is respectively closed. Each cold air preventing plate 5 is openably disposed at the freezer or the cold storage chamber, and formed of synthetic resin or rigid glass through which the internal part of the cold storage chamber body 2 and the opening and closing door 3 is seen. Thus, since substances to be contained in the freezer or the cold storage chamber are seen without release of the cold air prevention plate 5, the substances to be contained are taken out in a short time.  Further, since, even when the opening and closing door 3 is in a release state, emission of cold air to an external part is prevented by the cold air preventing plate 5, the increase of the temperature of the infernal part of an electric refrigerator is suppressed and power consumption of the electric refrigerator is reduced.

Filed: 1991-09-02
Abstract: PURPOSE:To provide a monitor picture with excellent reproducibility by forming a comparatively transparent half mirror film to a front side or a rear side of a cover made of a transparent plastic to conceal a color camera. CONSTITUTION:A comparatively transparent half mirror film 4 made of a chromium nickel and an iron is formed on a front side or a rear side of a cover 2 made of a transparent plastic to conceal a color camera 3 equipped on a base 1 by the sputtering method.
