Title: Method and apparatus for production of silicon carbide single crystal
Inventor: MORIYA AKIHIRO
IPC: C30B29/36
Filed: 1988-06-03
Abstract: PURPOSE:To obtain the good-quality silicon carbide single crystal having a large sectional area by inserting the projecting parts provided to a seed crystal imposing part into the grooves formed on the rear surface of a silicon carbide seed crystal substrate to hold the substrate and growing the crystal on this substrate. CONSTITUTION:The grooves 2a are formed to approximately the center of the parallel flat plate-shaped silicon carbide seed crystal substrate 2 by a crystal cutting machine having diamond edges in such a manner that the groove coincide with the projecting parts of the seed crystal imposing part. The seed crystal substrate 2 is then subjected to surface treatment such as washing with pure water, alkaline etching and acid etching. On the other hand, a graphite crucible system formed with the projecting parts 1b corresponding to the projecting parts of the seed crystal imposing part 1a is previously heat treated. The silicon carbide 4 in packed in the graphite crucible 3, further, the seed crystal material 2 is installed on the imposing part 1a by inserting the projecting parts 1b of said part into the grooves 2a. The graphite crucible system is then installed in a reaction vessel and while gaseous argon pressure is maintained in the container, silicon carbide powder 4 is heated and the temp. gradient is so set that the temp. of the imposing part 1a attains a prescribed temp., by which the crystal growth is executed. The silicon carbide single crystal is thus formed on the seed crystal substrate 2.

SOLUTION: In a device wherein a valve plate is push-pressed to a cylinder block side by acting delivery pressure in a delivery chamber disposed on a back surface of a valve plate on which a suction chamber 19 is formed so as to prevent opening/separating a sliding surface between the cylinder block and the valve plate, a groove 62 is inscribed on an outer peripheral surface of the valve plate, a seal ring 61 is fittingly inserted into the groove 62, and the seal ring 61 elastically abuts on a hole part 60 of a cover 6. Accordingly, a drain chamber 2 and a suction port 24 are cut off. When oil is sucked to a suction chamber 19 disposed on the valve plate through a suction port 24 by a swash piston pump, it is obstructed that drain oil in the drain chamber 2 is sucked by the seal ring 61, so that failure of the pump is prevented.

Title: Memory card
Inventor: NAGATA YASUNORI
IPC: B42D15/10
Filed: 1991-05-14
Abstract: PURPOSE:To obtain memory card with high quality, where the lost and change of data due to the consumption of a second battery does not occur by battery- checking the second battery optically at the time of exchanging the first battery. CONSTITUTION:A battery holder 3 is contained in a containing part 4 formed at the other end side of IC module 1 in the RAM card and the first battery 8 and the second battery 9 are respectively fitted and held on the battery holder 3. An optical element electrode 7 contacts with the positive electrode of the second battery 9 when the battery holder 3 moves along with the pulling direction (A direction) and the optical element 10 emits light unless the second battery 9 is consumed. The diminution state of the second battery 9 is known by the optical element 10 before the power supply of the first battery 8 stops. Therefore, the diminution state of the second battery 9 is visually judged by presence or absence or lightness in the emission of the optical element 10 at the time of the exchanging work of the first battery 8.

Title: Picture recording device
Inventor: KISHIMOTO YOSHIO
IPC: B41J2/065
Filed: 1979-10-24
Abstract: PURPOSE: To improve the rise form and supply of the toner and the picture vividness, by using a magnet, where two magnets, at least, are stuck to each other with the same poles opposite to each other, as the magnetic force source for the multistylus of the head.  
     CONSTITUTION: A magnet where two magnets 5 and 6, at least, are stuck to each other with the same poles opposite to each other is used as the magnetic force source for multistylus 1 of the head. Though this magnet is difficult for adhesion because magnets are caused to adhere to each other in the repulsive direction, rise of magnetic fluid 3 is very suitable, and supply of magnetic fluid 3 is improved. If soft  magnetic plate 7 is inserted as shown by (d), magnetic force lines flow in the face  direction of the plate smoothly, and therefore, repulsion of magnets 5 and 6 is  weakened to facilitate adhesion. Since adhesion variance between magnets 5 and 6  does not appear as magnetic variance, the rise magnet of uniform magnetic force  can be produced. Thus, the rise form and supply of the toner are improved to improve vividness of pictures.

Title: Superconducting wiring
Inventor: FURUKAWA AKIO
IPC: H01L23/52
Filed: 1987-05-29
Abstract: PURPOSE:To maintain a wiring resistance small even if the superconductivity of a wiring is temporarily broken and to improve reliability by so wiring a metal as to cover at least part of an oxide superconductor. CONSTITUTION:Metal (e.g., gold) 1 is wired by depositing on a semiconductor or an insulating film of SiO2 or the like on the semiconductor 3, an oxide superconductor 2 is wired therein, and the metal 1 is further wired to cover it from above the superconductor 2. Thus, the superconductor 2 is entirely isolated from an exterior to prevent a crystal structure from varying. Further, since the metal is wired in parallel, even if the superconductivity is temporarily broken, a wiring resistance may not be increased. Or, a method for wiring the metal 1 to cover the superconductor 2 from above it by wiring the superconductor 2 directly on the insulating film of SiO2 on the semiconductor provides substantially the same effect.

Abstract: PROBLEM TO BE SOLVED: To increase the amt. of formed oil obtained from sludge and to enable even the modification of the formed oil. SOLUTION: Dried sludge is heat-treated in a gasifying part to obtain a gaseous product 12 and waste oil is added to a liquid 13 obtained by condensing the oily substance of the gaseous product 12 and the resulting mixture is heated by a heater to obtain a gaseous product 15 containing the waste oil component in a gasified state.

Title: Sheet material feed device
Inventor: SAOTOME SUMITOSHI
IPC: B65H3/52
Filed: 1986-06-13
Abstract: PURPOSE:To stably and surely feed a sheet-like material, by attaching a sheet material separating member on the top section of a sheet material separating mechanism so that it is pressed against a feed roller. CONSTITUTION:A sheet material separating mechanism 2 is pressed against a feed roller 1 under a force F by a spring. When the feed roller 1 rotates clockwise, the topmost sheet material 7a is drawn in the feed direction to be fed into between the roller 1 and a pad 3a. At this time, the sheet material 7b right below the topmost sheet material 7a is dragged by the latter, and therefore, is fed into between the roller 1 and the pad 3a. However, the leading end of the overlappingly fed sheet material 7b abuts against a curved section 31 in the pad 3a so that its advancing direction is changed to cancel out its inertia force, resulting in stopping of the sheet material 7b. Meanwhile, the contact area of the topmost sheet material 7a with the feed roller 1 is increased so that it may be surely fed out.

Abstract: PURPOSE:To enable data erasing operation with a low source voltage by setting a threshold voltage, obtained when a voltage is applied to a control electrode under the condition that a charge accumulating electrode is electrically neutral, to a value higher than the predetermined value and is lower than the predetermined threshold voltage after accumulation of charges. CONSTITUTION:A threshold voltage obtained when a voltage is applied to a control electrode under the condition that a charge accumulation electrode is electrically neutral is set to a range higher than 0 volt and is lower than 1/2 the threshold voltage after accumulation of charges to the charge accumulation electrode. Thereby, a voltage to be applied to impurity region is lowered while data is erased. For the control of threshold voltage, a source region 8 of a memory cell is covered with a resist mask 9 and boron is implanted to the area which becomes a drain region. Moreover, arsenic is implanted to form a drain region 10. A threshold voltage of a memory cell can be controlled easily depending on the amount of impurity to be implanted to the drain region 10.
