Title: X-ray microscope
Inventor: OGURO TOSHIKI
IPC: G01N23/223
Filed: 1989-12-28
Abstract: PURPOSE:To improve sensitivity and resolving power and to expand an application range by uniformly electrostatically charging the photoconductive layer of an electrophotographic sensitive body, placing a sample between the photosensitive body and an X-ray source and irradiating the sample with an X-ray. CONSTITUTION:The X-ray transmission image of the sample P is recorded as an electrostatic latent image on the photoconductive layer 9 of the electrophotographic sensitive body 8 disposed to face a microfocus X-ray tube 3 when the photoconductive layer 9 is uniformly electrostatically charged and the sample P is placed between the photosensitive body and the X-ray tube 3 and is irradiated with the X-ray. The surface of the photoconductive layer 9 is scanned by the electron beam radiated from a lens barrel 4 provided on the other surface side of the photosensitive body 8 during or after photographing. The secondary electrons of the quantity meeting the latent image potential are released from the spot irradiated with the electron beam at this time. The quantity of the secondary electrons is detected by a multichannel type video amplifier tube (MCP) 5 provided near the photoconductive layer 9 and the latent image potential is indirectly measured from the quantity of the secondary electrons. The output of the MCP 5 is converted via a control section 6 to a video signal which is visualized in real time by a CRT 16.

Title: Female thread forming die
Inventor: KATAYAMA ICHIRO
IPC: B23G5/04
Filed: 1993-12-17
Abstract: PURPOSE:To absorb the elongation of a work due to plastic deformation and prevent a die from being affected by unnecessary thrusting force by providing an equal lead part, in which the lead angle is gradually increased from the machining starting side to the machining termination side, in a part of a spiral groove. CONSTITUTION:The lead angle of unequal lead part 32 divides the total length (l) of a spiral groove 12 of the unequal lead part 32 into n-equal divisions, and is adapted to be increased by a specified micro angle phi obtained by dividing (theta2-theta1) (theta1 is the lead angle of the equal lead part 30, theta2 is a specified lead angle of the equal lead part 34) into n equal divisions, each time the equally n-divided micro length DELTA1 is advanced. That is, the lead angle between the starting point B of the unequal lead part 32 and a point b1 situated in rear end side by the micro length DELTA1 from the point B along the spiral groove,m becomes theta1+phi by adding the micro angle phi to the lead angle theta1 of the equal lead part 30. The lead angle of the micro length DELTA1 between the points b1 and b2 along the spiral groove becomes theta1+2phi. Thus, the lead angle is adapted to be increased nearly linearly along the spiral groove 12 between B and C.

Title: Surface treatment agent
Inventor: OKAMOTO KOICHI
IPC: E02D9/02
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To provide a surface treatment agent to be attached to the surface of a buried body for restricting adhesion of the buried body and hydrate of hydraulic composition to each other in a structure composed of the buried body such as an H-steel, and hydrate of hydraulic composition such as cement hydrate.

Title: Extrusion controlling method of fluff-like resin material
Inventor: UEDA KAZUMI
IPC: B29C48/92
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To make the adjustment by an operator to the change in the bulk specific gravity of a material unnecessary and keep a constant extrusion output at all times by a method wherein the load current of an extruder driving motor is controlled at nearly constant by changing the supply of a volumetric material feeder in response to the change of the load current of the extruder driving motor. SOLUTION: When the bulk specific gravity of a fluff-like resin material fed from a volumetric material feeder 4 changes to be larger during the running of an extruder 1, the melting and kneading load of a screw la increases or changes to be smaller the melting and kneading load of the screw la decreases. As result, the variation of the melting and kneading load is represented by the variation of the load current of an extruder driving motor 3.  Accordingly, by decreasing the rotational frequency of a feeder driving motor 5 when the load current value 6b of the extruder driving motor 3 increases or by increasing the rotational frequency of the feeder driving motor 5 when the load current value 6b decreases, the supply of the flufflike resin material to the volumetric material feeder 4 is decreased or increased in response to the increase or decrease of the resin material in the extruder 1.

Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To provide an automatic travel type tea-picking machine capable being simply driven by everyone and not causing the contamination of old leaves and the shallow and deep picking of tea leaves. SOLUTION: A pinion 25 is disposed on the rotation shaft of a travel handle 22, and can be rotated with a rack 26 forward or backward moved with a hydraulic cylinder 27. Right and left detection plates 43, 44 detect the positions of both the side portions 53a, 53b of a tea field ridge. When a difference between the resistance values of both variable resistors 47, 48 on the basis of the rotation angle of the detection plates 43, 44 reaches a prescribed value, an electromagnetic switch valve 31 is switched in e.g. a symbol (a), and the piston rod 28 of the hydraulic cylinder 27 and the rack 26 are forward moved. The pinion 25 and a driving handle 22 are subsequently rotated clockwise.  Thus, the travel direction of the automatic travel type tea-picking machine is automatically changed in response to the positions of both the side portions of the tea field ridge 53 detected with the detection plates 43, 44, and the automatic travel type tea-picking machine accurately travels along the tea field ridge 53. Thereby, the machine can simply be driven by everyone, and does not cause the contamination of old tea leaves and the shallow or deep picking of tea leaves.
