Title: Coat transfer tool
Inventor: ONO MASAHIKO
IPC: B65H37/00
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To make it easy to confirm a position in which a coat transfer is ended when using a coat transfer tool of such a type that a transfer head is rotatable. SOLUTION: The center line SB of the thickness of a pressing transfer part 22 on a transfer head 14 is inclined, at an angle (a) on the side of a face to which a coat is transferred, with the center line SA of a rotary shaft 20 on the transfer heat 14 which is mounted, in a rotating manner, on a body 12. Therefore, it is possible to increase an inclination angle D1 of the pressing transfer part 22 with the face to which the coat is transferred and a space P between the body 12 and the face over the inclination angle D1 and the space P of the conventional coat transfer tool. Thus it is easier to confirm a position at which the coat transfer is completed by the pressing transfer part 22, obliquely from above, compared to the conventional coat transfer tool.

Title: Range finder having linear laser light spot oscillator
Inventor: KUBO HIROYUKI
IPC: G01B11/00
Filed: 1985-08-28
Abstract: PURPOSE:To enable a smaller size and lighter weight of the equipment as a whole, by mounting a collimator lens and a cylindrical lens in front of a semiconductor laser oscillator used as laser oscillator in such a manner as to adjust the focusing. CONSTITUTION:The body 35 of a laser range finder 40 with a specified length is supported on a base 31 in such a manner as to be rotatable about the axis line thereof and a laser oscillator 40 capable of oscillating laser light is mounted on the one end side of the body 35 while an image sensor 37 is provided oscillable on the other end side thereof. An arithmetic processor 46 is connected to the image sensor 37 to perform a computation processing of the video output thereof. Then, a small and light semiconductor laser oscillator is used for the oscillator 40 and oscillates a laser light directly, focused with a collimator and further diffused linearly with a cylindrical lens to be projected to an object to be measured. Then, the reflected light forms an image perpendicular to a train of line sensors of an image sensor 37 and is displaced on the line sensors according to charges in the projection spot along the length thereof. This can reduce the size and the weight of the equipment as a whole and enables the laser light to form an image on the line sensors accurately and positively.

Title: Test device package
Inventor: MORIKAWA NAOTAKA
IPC: G01N31/22
Filed: 1988-07-27
Abstract: PURPOSE:to prevent the peeling of a test layer by packaging a test device with a test layer on one side thereof and an anti-denaturalization agent to prevent denaturalization and degradation of the test layer in such a manner that the anti-denaturalization agent is positioned on the side with no test layer formed. CONSTITUTION:A test device 2 and a desiccating agent 6 as positioned on the side B of a support 3 are housed in a packaging material 7. With the action of the drying agent, moisture in the packaging material 7is absorbed to prevent denaturalization otherwise caused by moisture of a test piece 4. When the test device 2 is taken out of the packaging material 7, the packaging material is opened by breaking it with a notch 9 and it is pulled in a direction of the arrow by picking the rear end of the support 3 exposed with fingers. Here, as the desiccating agent 6 is located on the opposite side to the test piece 4 sandwiching the support 3, the test piece 4 will not contact the drying agent so that the desiccating agent is not scraped out of the packaging material 7 to be scattered outside. This also eliminates the peeling of the test piece otherwise caused by a contact of the test piece 4 with the desiccating agent 6.

Title: Solid electron beam generator
Inventor: MIYAWAKI MAMORU
IPC: H01J1/308
Filed: 1986-08-12
Abstract: PURPOSE:To increase quantity of electrons emitted by injecting electrons from a 1st range to a 2nd range and emitting the electrons from an electron emission surface in the 2nd range. CONSTITUTION:In forming a heterojunction structure of a 1st layer 8 including a 1st band gap, and a 2nd layer 10 including a 2nd band gap which is narrower than the 1st band gap on an epitaxial film of GaAs provided on a substrate 1 of Si, an inclined layer 20 in which ratio of mixed crystals of a certain material is gradually changed is inserted between the 1st layer and the 2nd layer, and electrons are injected from the 1st layer to the 2nd layer, while the electrons are emitted from an electron emission surface of the 2nd layer. Due to insertion of the inclined layer 20 between the layer 8 and the layer 10, ratio x of mixed crystals of A1 is gradually reduced, reaching 0 at the boundary with the base layer 10. Because of this insertion of the inclined layer 20, spikes or the like are not produced in the hetero-boundary between the layer 8 and the layer 10. Thus quantity of electrons emitted can be extremely increased.

Title: Forming method for fine pattern
Inventor: UESUGI FUMIHIKO
IPC: G03F7/26
Filed: 1994-08-11
Abstract: PURPOSE:To directly pattern in the production process of LSIs by transferring a mask pattern in an equal or reduced size and selectively growing an inorg. resist on the pattern. CONSTITUTION:The pattern of a mask 12 is transferred in a reduced size on a Si substrate 1 through a convex mirror 21 and a concave mirror 22. The light passing through the mask 12 can excite inner-shell electrons of Al(CH3)2H which is the source gas of Al to be used for an inorg. resist and can form an AlC film 15 on the substrate 11. Therefore, the AlC film 15 is formed on the pattern formed by transferring the pattern of the mask 12 in a reduced size. Then, by heating the substrate, thermal CVD of Al is produced and Al grows only in the area where the AlC film 15 is not formed. Thus, the Al film as an inorg. resist grows on the pattern formed by transferring of the pattern of the mask 12 in a reduced size. Then, this Al film is used as a mask 12 and the substrate 11 is etched to obtain the mask pattern in a reduced size on the substrate 11.
