Title: Construction method of large-depth large-scale underground space by ground freezing method and ground freezing pipe therefor
Inventor: ASAI KATSUTOSHI
IPC: E02D3/115
Filed: 1990-03-06
Abstract: PURPOSE:To construct a large depth underground space in the sandy underground under high pressure water by constructing peripheral contour shield tunnels from each level of a vertical shaft constructed from the ground, and constructing freezing pipes with these tunnels as start-arrival bases to freeze the ground. CONSTITUTION:An outer pipe 13 is pushed forward underground as a propulsion pipe following a tip cutter, and with this outer pipe 13 as an outside guide, an inner pipe 14 is inserted therein. A refrigerant is circulated at the gap cross section 15 between both pipes 13, 14 to perform ground freezing to the peripheral ground across a large range region. Ground freezing pipes 9... are constructed at the four peripheral side wall parts 10 of a large depth underground space 1 to be constructed, and when the excavation and construction of vertical shafts 2 reach the batholith level of the underground space 1, peripheral contour shield tunnels 7 are constructed horizontally. With these tunnels 7 as start arrival bases, ground freezing pipes 8... are constructed at the whole face of the batholith part 6 to perform a ground freezing process. A large space can be thus constructed very deep in the underground.

Title: Ciphering key distribution system
Inventor: OKINAKA HIDEO
IPC: G06F21/10
Filed: 1986-03-14
Abstract: PURPOSE:To enhance the secrecy in the ciphering key distribution by allowing a mobile station to generate an effective ciphering key to a call at every time it takes place, informing the key to a base station with excellent reception performance and applying ciphering communication using the ciphering key. CONSTITUTION:When a call takes place in a base station, the station distributes a call occurrence notice 9 to a mobile station. The mobile station receiving the call occurrence notice 9 distributes a ciphering key in a reply notice 11. The base station receiving the reply notice 11 informs the channel assignment notice 12 to the mobile station and uses the ciphering key in reply notice to make talking 13. When a call takes place in the mobile station, a ciphering key is given in a call occurrence notice 15 and sends it to the base station, where the notice 12 is sent to the mobile station. The talking 13 is applied by using a set ciphering key. Since the reception performance of the base station is far better then the reception performance of the mobile station, the ciphering key is not leaked to other mobile stations.

Title: Puncture preventor for tire
Inventor: KOMURO SUTEJI
IPC: B60C19/12
Filed: 1979-05-04
Abstract: PURPOSE: To prevent a tire puncture protecting means from separation and to improve durability of the tire by a method wherein both right and left sides of the tire puncture protecting means having a curved surface suitable to the whole internal circumference of the tire are fixed beneath push wire pieces.  
     CONSTITUTION: Both sides of the flat surface 6 of the tire puncture protector 1, which is composed mainly of steel and rubber and has a curved surface 4 suitable to the internal circumference of the crown part 3 of the tire 2, are fixed by force to the internal circumference of the crown part 3 by keep plates 5. If this structure is used, even when nails, etc. are stuck, they are hindered from penetrating the tube and bent by the protecting material 1 and protected from reaching the tube and therefore the tube is protected from puncturing. Thus, since the puncture protecting means 1 is fixed by keep plates which can or cannot be separated from the tire, the tire is not in danger of separation after a long time of period.

Title: Copying method
Inventor: OHATA AKIRA
IPC: B65H5/02
Filed: 1994-02-28
Abstract: PURPOSE:To obtain a copying method capable of copying the first image or the last image at a prescribed position on a sheet, even in the case where the number of originals is an odd number by relatively changing the stopping position on original platen glass of the original sent out in the beginning or in the end and the copy starting position on the sheet. CONSTITUTION:When the number of the originals is an odd number, the last original is set in the position on the original platen glass 29 at a distance by the original size from the exposure reference SP and from a scale 120, namely, the intermediate position. Then, as a result of copying to the last, if the last original for copying is only one, it is set on the scale side, hence the latter half erase flag is raised. When the small size copy and the large size copy are set in a state of two-in-one, only the small size original set on the side of scale is copied and the large size original is erased, therefore the latter half erase flag is raised, too. The copying process for the large size original is performed at the next place so as to perform the full surface copying. Thus, the image of the last original is copied in the prescribed position on the sheet.

Title: Magnetic disk device
Inventor: TAKAHASHI NOBUYOSHI
IPC: G11B33/14
Filed: 1985-03-18
Abstract: PURPOSE:To suppress a temperature rise of internal air even if a heating value of the inside of a magnetic disk device increases, by providing a gas reservoir of a non- condensable gas on the end part of the outside of a base plate of a rotation driving shaft. CONSTITUTION:A titled device is provided with a gas reservoir 22 which is provided on the end part projected to the outside from a base plate 1 of a rotation driving shaft 2A and contains a non-condensable gas 11 in the inside under an operating environmental temperature condition of the magnetic disk device. When a heating value of the magnetic device increases, the temperature of the rotation driving shaft 2A rises, the vapor pressure of a condensing heat exchange medium 5 rises, a heat transfer area of a condensing part 23 expands and an interface heat resistance decreases. That is to say, when a thermal load of a rotation driving shaft evaporating part in a spindle motor 10 and in the base plate 1 increases, a heat transfer resistance of the condensing part decreases, and both a vapor temperature and a heat transfer quantity increase. Accordingly, the pipe wall temperature of the rotation driving shaft, and a sealed air temperature of the magnetic disk device are maintained in a prescribed temperature range, even if the heating value increases. In this way, the generation of heat off-track can be suppressed.

That is, the presence or absence of the potential-stabilized rotation of the photoreceptor 1 is controlled in accordance with the carrying time from the paper feeding tray to the transferring part on a paper carrying part 8 so as to change the image forming condition in accordance with the presence or absence.

Title: Soil conditioner
Inventor: OSATO YOSHITARO
IPC: C09K17/00
Filed: 1993-03-16
Abstract: PURPOSE:To provide a soil conditioner having no foreign odor and being almost freed from fat and salt and relatively small in the content of nitrogenous, phosphatic and potash components. CONSTITUTION:A finely divided vegetable product such as a press residue of apples is used, and water is added to this residue. Calcium oxide is added to the obtained mixture and reacted, and the calcium compounds resulting from the reaction are mixed with and dispersed in fibers of the residue. In this, way, calcium hydroxide, calcium carbonate and an organocalcium compound such as a calcium salt of an organic acid are homogeneously mixed with the vegetable fibers to form a soil conditioner being relatively small in the content of nitrogenous, phosphatic and potash components and assuming alkalinity. When this conditioner is applied to soil, its calcium compounds can be satisfactorily dispersed in the soil and exhibits its alkalinity to neutralize and alkalify the soil without fail and to suppress the growth of bacteria adversely affecting plants through its disinfective effect. Because it is a mixture of vegetable fibers, it can absorb air among the fibers to improve the soil when mixed with soil.
