Title: Piercing method of stepped cylinder
Inventor: TOYAMA TAIJI
IPC: B21D28/28
Filed: 1983-07-28
Abstract: PURPOSE:To work a hole of relatively high accuracy extending from the bottom to stepped cylindrical part by piercing an under hole on the bottom and applying tensile force to the flange part in the direction of drawing when drawing the stepped cylindrical part. CONSTITUTION:A circular blank is blanked from a plate and a flanged 9 semiprocessed product 8 is manufactured by repeating drawing. When working a stepped cylindrical part 3, tensile force is applied to he flange 9 in the same direction as drawing, that is, downward, shortly before completion of drawing. The size of the hole 4 can be determined accurately by way of application of the tensile force. Accordingly, test work is performed once, and the difference is adjusted by changing the length between the bottom 2 of the semiprocessed product 8 by changing height of drawing until preceding process adjusting die height of a press. The flange part 9 of the stepped semiprocessed product 10 is trimmed in succeeding process.

Title: Fluorescent lamp
Inventor: NOMOTO IKUYA
IPC: H01J61/16
Filed: 1982-08-11
Abstract: PURPOSE:To make it possible to improve starting performance of a lamp and reduce a charged krypton amount along with the improvement of the flickering of a lamp at lower temperature and the reduction of a lower temperature light flux by charging the lamp with a mixed gas of three kinds of krypton-neon- argon in the starter type linear power-saving fluorescent lamp reduced in its diameter. CONSTITUTION:In a fluorescent lamp having its tube length ranging from about 580mm. (20W) to about 1,200mm. (40W) and its tube diameter ranging from 23mm.- 31mm., its lower temperature starting characteristic is improved by charging the lamp with rare gases obtained by properly mixing krypton, argon, and neon with the charging pressure of 1.5mm.Hg-2.5mm.Hg. Lower temperature starting voltage is further lowered by selecting Ne/Kr=0.1-0.2 as a gas mixing ratio. The reason is because the consumption of an electrode emitter caused by the excess Ne gas charging is undesirably increased when said ratio is about 0.2 and starting voltage reduction effect is insufficient when said ratio becomes less than 0.1. Moreover, in the tube diameter ranging from 23mm.-27mm., the lower temperature starting voltage is more further reduced by selecting Ne/Kr=0.1-0.4.

Filed: 1989-06-02
Abstract: PURPOSE:To prevent a fixer from being scattered and mixed into a developer because of shock or vibration by returning the processing liquid in a processing unit to a return unit at the time of detecting abnormality by a shock/vibration sensor. CONSTITUTION:This automatic developing machine consists of a processing unit 100 which forms a visible image by development processing of a photographic sensitive material and a return unit 200 which a developer 1, a fixer 2, and washing water 3 are returned to and temporarily stored in at the time of emergency. The sensor to sense vibration or shock is provided; and when the output of the sensor exceeds a prescribed value, at least the liquid surface of the fixer is reduced or the fixer in a fixing tank 2 is transferred to auxiliary tank 15 and is returned to the tank 2 thereafter. Thus, the fixer is prevented from being mixed with the developer when vibration or shock is applied to the automatic developing machine.

Title: Defect checking device for long-sized sheet
Inventor: TAKEMATSU YOSHIAKI
IPC: G06T7/00
Filed: 1988-06-06
Abstract: PURPOSE:To improve the defect check precision of a long-sized sheet by providing calculating means of the centroid position in the scanning direction of a repeat pattern, a meandering extent calculating means, and a meandering correcting means. CONSTITUTION:An image sensor camera 1 continuously picks up an image in the direction orthogonal to the movement direction of the sheet and sends the video signal of the repeat pattern image on the sheet to an amplifier 2. An amplified signal (a) is compared with a preliminarily set threshold voltage Vth to obtain a binary signal (b). A meadering correcting circuit 4 corrects the binary signal (b) with the extent of meandering fed back from a centroid detecting circuit 5 and sends the result as a video signal (c) to a memory 6 and a defect discriminating circuit 7. The inputted corrected signal (c) is successively stored in the memory 6 and is periodically sent to the centroid detecting circuit 5. This circuit calculates the centroid of a specific pattern of the repeat pattern and sends the deviation from a learnt reference position to the meandering correcting circuit 4. The discriminating circuit 7 uses a reference mask pattern to mask the corrected signal (c) at the pattern repeat period, and it is discriminated whether a remining picture is defective or not, and the result is outputted.

Abstract: PURPOSE:To obtain a sheet cutting mechanism having a simple construction and high cutting reliability by installing a guide member at a predetermined inclining angle with respect to the face of a storing medium, and varying the medium cutting point of a cutter blade upon movement of a carriage member. CONSTITUTION:A cutter carriage 2 and a feed screw 3 are provided between plates 1 and 2, a guide shaft 4 is secured, and the screw 3 and the shaft 4 are installed at an inclining angle alpha deg. with respect to the surface of a rolled sheet 6.

Since the plates 7, 8 press the vicinity of the part to be cut of the sheet 6, the sheet 6 can be easily cut. Since the screw 3 and the shaft 4 are inclined at alpha deg. with respect to the surface of the sheet 6, the contact point of the blade of the cutter 13 with the sheet 6 is always varying while the sheet 6 is cut, thereby reducing the wear of the blade of the cutter.

Title: Biaxially oriented polypropylene film
Inventor: TSUNASHIMA KENJI
IPC: C09J7/02
Filed: 1979-10-31
Abstract: PURPOSE: To improve a high rigidity, an easy tearing property, a transparency and a glossy property and obtain a film more excellent than cellophane by method wherein a Charpy impact strength and an interface average refractive index of a biaxially oriented polypropylene film are limited within a specified range.  
     CONSTITUTION: A biaxially oriented polypropylene film having 1.510 or more of an interface average refractive index and a Charpy impact strength within a range of 50W130(kg.cm/mm 2 ) is provided. Above-described Charpy impact strength is a reference value for an easy tearing property of the film and if the value is within a range of 50W130kg.cm/mm 2 , the easy tearing property may be obtained. In order to make the rigid film excellent in a resistance to impact while maintaining the easy tearing property, it is necessary that the interface average refractive index should be 1.510 or more. This is because that, if the interface averge refractive index is less than 1.510, the resistance to impact, Young's modulus and an ultimate strength thereof are made week and the film will lose a high rigidity and a feeling of cellophane.
