Title: Method for forming score for folding
Inventor: HASHIMOTO TADASHI
IPC: B29C53/06
Filed: 1993-06-30
Abstract: PURPOSE:To fold a sheet at an accurate angle to make up a doll case or small box with a good surface flatness by a method wherein grooves and ridges are formed on the tip of a scoring edge and/of the surface of a support to form small grooves and ridges on the inner surface of a score of the sheet and the opposite side of the sheet from the score in order to absorb the folding stress and make the folding easy. CONSTITUTION:A hard plastic sheet 2 such as made of polyvinyl chloride and polypropylene is pressed between a scoring edge 4 and a support 5 to form a score 11 on the plastic sheet. During this time, since small grooves and ridges 41 and 51 are preformed on the tip of the scoring edge 4 and/or the surface of the support 5, small grooves and ridges 3 are formed in the inner surface of the score of the plastic sheet and/or the opposite side of the sheet from the score. Although a large number of the grooves and ridges 3 may be formed widthwise in the cross section of the score 11, it is generally preferable that the width and depth of the groove or ridge be about 5-100 microns.

IPC: H02J7/10
Filed: 1990-06-20
Abstract: PURPOSE:To achieve a stable mass-production which matches a production process capacity by setting the number of diodes to be connected between power supply voltages to any number and by allowing detection voltage to be matched to temperature characteristics of the battery voltage. CONSTITUTION:A reference voltage generation circuit 4 outputs a constant voltage which does not depend on power supply voltage. Then, a diode 10 and resistors 7-9 are connected between a positive power supply terminal 1 and a negative voltage terminal 2 of a power supply, and the voltage between the terminal 1, 2 is detected. The intermediate potential and the output of a circuit 4 are compared by a voltage comparator 5 and the output is output to an output terminal 3 through an output buffer circuit 6. Then, by setting the number of diodes 10 and current flowing through them to arbitrary values, detection voltage temperature characteristics which match negative temperature characteristics of battery voltage can be obtained. Thus, detection voltage accuracy required for a circuit from product specifications can be relaxed and a stable mass-production can be performed with detection voltage accuracy according to the production process capacity.

Title: Improvement of toughness in joined part of flash butt welded steel
Inventor: ISHIKAWA HAJIME
IPC: C22C38/00
Filed: 1990-06-20
Abstract: PURPOSE:To obtain toughness at low temp. by means of post weld heat treatment by air cooling or forced air cooling excellent in workability even in the cold district by properly combining steel components with post weld heat treatment. CONSTITUTION:Flash butt welding is applied to a steel having a composition consisting of, by weight, 0.02-0.08% C, <=0.60% Si, 1.70-2.00% Mn, 0.01-0.08% Nb, 0.005-0.030% Ti, <=0.06% Al, and the balance iron. The resulting joined part is heated up to 950-1050 deg.C and cooled through the temp. region from 800 to 500 deg.C at <=5 deg.C/s cooling rate. Since C content is reduced and reheating temp. is elevated to high temp. to allow Nb to enter into solid solution and also Mn content is increased to increase the transformation strengthening and precipitation hardening of Nb, strength and toughness can be secured. Further, since C content is reduced and cooling velocity after reheating is decreased to control the formation of hardened structure, such as island martensite, and trace amounts of Ti are added to inhibit the growth of austenite at the time of heating, toughness at low temp. can be secured.

Title: Automatic dimming electronic flash device
Inventor: HORINISHI KATSUMI
IPC: G03B15/05
Filed: 1980-11-17
Abstract: PURPOSE:To permit the use of a titled device also as an ordinary automatic dimming flash device other than the exclusive use by so constituting the same that a control circuit for quantity of light operates in spite of an open or short circuit state of a terminal to be supplied with electric signals. CONSTITUTION:For example, if a terminal A is open without using an exclusive camera, the output of an operational amplifier 19 goes zero, and a voltage comparator 15 emits an output signal of a high level. The voltage obtained by dividing a high level output signal with resistances 13, 14 is supplied to the inversion input terminal of another voltage comparator 10. Therefore, when the terminal voltage of an integrating capacitor 11 attains the voltage value divided by the resistances 13, 14 on account of the photocurrent flowing through a photosensor 9, the light emission operation of a flash discharge tube 6 is controlled by a light quantity control part 7. With such constitution, a control circuit for quantity of light is operatable, although the terminal A is open. Hence, this is usable both as an exclusive automatic dimming flash device and as an ordinary automatic dimming flash device other than for the exclusive use.
