Filed: 1995-06-29
Abstract: PURPOSE: To simplify form construction and shorten man-days while executing forms on a field in a cold district or winter construction work safely at a low cost. CONSTITUTION: Parallel tabular body forms 1 consist of foamed polystyrene, and have irregular engaging sections 3, 4 and 6, 7 connecting the tabular bodies adjacent to the upper and lower edge sections and both-side edge sections of the tabular body. T-shaped grooves 2 fitting the edges of I-shaped or U-shaped connecting members interposed and arranged among the forms 1, 1 so that the tabular forms 1 are frame- worked oppositely at intervals are formed on the internal surface sides of the parallel tabular bodies extending over approximately central sections from upper-edge sections or lower-edge sections, and forms made of a synthetic resin are manufactured.  Accordingly, field execution in a cold district can also be conducted without generating a freezing trouble by the heat-insulating function of the forms, man-days can also be shortened largely and a framework is handled simply because of the lightweight forms, the forms can also be manufactured without depending upon the conditions of operation while the removal of the forms and the post-treatment of cleaning operation can be omitted, and appearance quality can also be improved and form construction is simplified.

CONSTITUTION:In manufacturing cheeses, or cones, of an elastic yarn 2 wound up on a circular bobbin 1, it shall be so arranged that the ratio of min. diameter R2 at the center of a wind-up cheese to the max. diameter R1 at the ear parts on its both ends, R2/R1, will be 0.8-0.99. Winding-up is so performed that the yarn at the ear parts 3 on their surfaces has a traverse angle below 5 deg. while the yarn at the center a larger traverse angle than those parts 3. The ratio of the length L2 of the portion having a larger traverse angle at the central part to the wind-up width L1 of the cheese, L2/L1, shall be 0.2 thru 0.9. Such a cheese is manufactured by pushing a conical roller 5 having an angle of 10-80 deg. to the shaft of a free roller 4 to the ear parts 3 immediately before or after the completion of winding-up.

Title: Ophthalmic image processing system
Inventor: KATO TAKEYUKI
IPC: G06Q50/22
Filed: 1993-07-29
Abstract: PURPOSE:To achieve a shortening of required diagnosing time by digitizing a cornea image data gained from reflected light obtained by admitting a light beam into the eyegrounds to transfer a part alone specified except for a margin. CONSTITUTION:Light beam of a halogen lamp 4 as light source for observation of a lighting optical system 1 is made to irradiate the eyegrounds Eq of an eye 3 to be inspected through various optical devices such as lenses, filters, slits and mirrors to observe the eyegrounds Ef. Then, the light source is switched to a xenon lamp 6 to irradiate the eyegrounds Ef. The reflected light from the eyegrounds Eq forms an image on an area CCD 30A of a TV camera 30 through various optical members of an observation image pickup optical system 2 and is displayed on a monitor TV 31 through a camera control circuit 40. The camera removes a margin in a perimeter from an eyegrounds image to extract a necessary part alone at the center thereof and performs an image processing. Then, the image is transferred to display. This constitution enables the shortening of image processing time and diagnosing time.

Title: Shutoff nozzle
Inventor: MIYAUCHI NORIHISA
IPC: B29C45/23
Filed: 1988-07-28
Abstract: PURPOSE:To prevent the resin leaked out from an operational lever connecting hole from reaching a nozzle heater therearound by fixing a weir board between the operational lever connecting hole formed on the nozzle body of a shutoff nozzle and the nozzle heater mounted on the peripheral surface of the nozzle body. CONSTITUTION:The outer periphery of a nozzle 3, namely, the outer periphery of a nozzle body 4 is provided with a nozzle heater 17, and a weir board is fixed between the heater 17 and the operational lever connecting hole 14. Since, in an injection process, the pressed condition of a needle 7 by an actuator is released, as an injection pressure in resin reservoir 10 within the nozzle 3 is increased, the needle valve 7 is pressed backwards, and a nozzle hole 11 is opened, so that the injection of resin is performed. While repeating these operation, the resin is filled in the gap between the rear part of the needle valve 7 and an axial hole 12 with the needle valve inserted thereinto, and reaches the diametrically operational lever connecting hole 14 through injection pressure, as a result, there might be a case that the resin leaks outwards therefrom. However, the resin leaked out is interrupted by the weir board 18, and never reaches the nozzle heater 17.

Title: Glow discharge treatment of type to make combination use of high-voltage peak pulse impression and glow discharge treatment apparatus
Inventor: HOSOKAWA TOMIAKI
IPC: C23C8/36
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To form a nitrided layer and diffused layer thickly down to the deep depth of an object to be treated without subjecting these layers to post stages and to shorten the glow discharge treatment time. SOLUTION: An impulsive glow discharge voltage of about 900 V which is generated by a main circuit and is 10 KH in an inverter frequency is supplied to a treatment vessel (anode) and the object to be treated in the treatment vessel is subjected to a glow discharge treatment. The inverter frequency is made to 100 kHz by delaying the glow discharge voltage by prescribed a slight time from the start of the dead time period DT of the glow discharge voltage Δt simultaneously therewith. For example, the high-voltage peak pulses belonging to the glow discharge region of about 10 KV are supplied to the anode for high-voltage peak pulses and the object to be treated which is housed in the treatment vessel is subjected to the discharge treatment by these high-voltage peak pulses and, therefore, the temp. is locally raised only in the local part where the arc discharge current flows.  The interatom distance is increased and the nitrogen N separated from iron nitride FeN is penetrated deep into the object to be treated. The nitrided layer and diffused layer may thus be rapidly and deeply formed.
