Title: Method of construction of building
Inventor: TANAKA SUSUMU
IPC: E04G21/14
Filed: 1994-12-28
Abstract: PURPOSE: To prevent rolling and falling during the lifting of an upper floor section by inclining a post, in which elongation is permitted in the axial direction but shrinkage is hindered, connecting one end of the post to an upper-layer side section and the other end to a ground fixed article and elevating the upper- layer side section in a specified height. CONSTITUTION: Temporary thin pillars 6 are removed while a beam frame 2 is left unmoved as it is. A roof truss 3 is lifted by a jack. A proper number of posts 11 are built between the upper and lower sections of a beam frame 8 and a building foundation 1 in an inclined attitude before the lifting of the roof truss 3 at that time. A proper number of posts 12 are disposed simultaneously in upright in a vertical attitude. The posts 11, 12 are formed in structure, in which elongation is permitted in the axial direction but shrinkage is obstructed. When the roof truss 3 is elevated, an obliquely built attitude is maintained in the posts 11, and prevention action is kept in the rolling and torsion of an upper-layer side section. An upright attitude is maintained simultaneously in the posts 12, and action, in which the load of the upper-layer side section is borne, is kept. Accordingly, installation to a building during construction is also facilitated, and a sudden rise in construction cost can be prevented.

Title: Control device for engine with supercharger
Inventor: IMAI SHOJI
IPC: F02B37/00
Filed: 1989-12-18
Abstract: PURPOSE:To perform smooth acceleration during demand of acceleration by providing a throttle control means with a control gain varying part to widely vary a control gain by an accelerator operation amount detecting means during demand of acceleration. CONSTITUTION:Based on accelerator operation acceleration detected by means of an output from an accelerator operation amount detecting means 64 during demand of acceleration, the control gain of a throttle control means 73 is widely varied by a control gain varying part 71. Thereby, when accelerator operation acceleration under a transient state between the starting of pedaling and completion of pedaling is detected during demand of acceleration, a throttle valve 16 is rapidly driven to a full opening position, where suction resistance is lowmost, by a throttle valve drive means 60. Like a device depending upon an exhaust turbosupercharger during demand of acceleration, a time lag occurs and smooth acceleration during demand of acceleration is effected without the occurrence of a response delay.

Title: Information transmitting device
Inventor: KIKUCHI SHIGEMASA
IPC: G06F13/00
Filed: 1988-12-27
Abstract: PURPOSE:To quickly perform a down-loading operation to the corresponding module interface in case a module has the cut-off/recovery of its power supply by using a power supply information detecting means and a module information generating means. CONSTITUTION:In case the power supply of a bus interface 8 is cut off during a system operation, this cut-off state is detected by a power supply cut-off/ recovery detecting part 15 and a flag generating part 16 produces a flag showing the cut-off of the power supply to output it to a register 17. An interruption control part 18 writes the contents of the register 17 including the channel number information received from an EEPROM 13, etc., into a specific area 19 of a main storage 2 and at the same time applies a single interruption to a CPU. Thus the CPU knows the cut-off of the power supply based on the information on the area 19, and the software discontinues the process to be applied to the relevant channel. When the cut-off power supply is recovered to the interface 8, a reloading operation is automatically given to a module interface. Thus a quick down-loading operation is attained without stopping the working of a computer system.

Title: Method for producing single crystal and device for producing the same
Inventor: SHIMIZU EIJI
IPC: C30B29/40
Filed: 1994-12-07
Abstract: PURPOSE: To obtain a plate-like or filmy single crystal without requiring a slicing process by passing the melted liquid of a single crystal raw material through an opening of specific shape and subsequently cooling the melted liquid. CONSTITUTION: A heater 3 is disposed on the outer periphery of a crucible 1 for melting a single crystal raw material 2. The melted raw material 2 is cooled and solidified in a cooling section 5 disposed outside the crucible 1 to produce a single crystal. Therein, an opening 4 is limited to a size of <=2mm length and >=10mm width, because when the thickness of the opening 4 is larger than 2mm, the cooling of the inner part of the produced single crystal is difficult, and a good single crystal can hot be obtained, and further, because when the width of the opening is shorter than 10mm, the uses of the obtained single crystal are limited, and its production cost is enhanced. Subsequently, the obtained single crystal is passed through the cooling section 5 to produce the crystal, which is moved so as to separate from the crucible 1.  A crystal is further produced at the tip of the moved crystal from the melted liquid.

Filed: 1993-12-27
Abstract: PURPOSE:To obtain an antenna for a compact portable terminal whose dimension is less than 1/4 of a used radio wavelength, realizing the excellent impedance matching with the high frequency part of a radio equipment. CONSTITUTION:On a finite ground 3 formed by a portable radio equipment body, a wire conductor 5 presenting a step-wise structure having the part in parallel to the finite ground 3 is fed as an antenna. A wire conductor which is close to the wire conductor 5 having the step-wise structure and has the part in parallel to one or plural other finite grounds 3 is placed on the finite ground in electrical contact with or in non-contact with the ground. As a result, because an antenna realizing the excellent matching with the impedance of a radio part can be realized with small volume and without a resonance part storing large reactive power, a compact antenna or an incorporated antenna to be applied to a compact portable radio equipment can be obtained.
