Filed: 1982-11-02
Abstract: PURPOSE:To form a surface non-defective layer positively, and to form internal defects in high density by growing a silicon epitaxial crystal on a silicon substrate in which the concentration of oxygen and carbon contained in a silicon crystal is limited. CONSTITUTION:When the concentration of oxygen made contain in the silicon crystal is Oi and that of carbon Cs, the silicon epitaxial crystal 11 is grown on the silicon substrate 10 in Cs>=Oi>=14X10<17>cm<-3>. The internal defects 12 are formed in the P type substrate 10 because various heat treatments are added through a process for forming a semiconductor element. The internal defects 12 are formed in high density because of Cs>=Oi>=14X10<17>cm<-3> at that time, and no internal defect is generated in the epitaxial layer 11 and the complete non- defective layer is formed because the layer 11 does not contain oxygen.

Title: Mechanism for cancelling elongation of wire
Inventor: KOBAYASHI TETSUO
IPC: G05G7/10
Filed: 1981-12-01
Abstract: PURPOSE:To enable to cancel the elongation of wire automatically during operating a driving devce by a method wherein two sets of pulleys equipped wihy a ratchet teeth on the opposing surfaces respectively are energized by an elastic member to approach them. CONSTITUTION:When a lever 21 is rotated into the detection of B, the first pulley 3 rotates into the direction of B, however, the ratchet teeth 3a, 4a are in non-engaging relation, therefore, a rotating torque is not transmitted to the second pulley 4. Accordingly, the second pulley is stopped until it is rotated by the tension of the second wire 7 after the first wire rotates a follower pulley 17 and the second wire 7 is wound by the follower pulley 17. At that time, the elastic member 5 functions as a brake with respect to the second pulley 4. According to this method, the elongations, generated in the first and the second wires 6, 7, are cancelled by being wound by the first pulley 3 extra when the lever 21 is rotated the direction of B.

CONSTITUTION:Sticks of incense on a drying shelf which is fed by a supply conveyer 1 are sucked by an absorbing drum 12 and are then shifted onto a transfer device 8 to a stick loosening device 19 in which flat belts 20, 20' stacked one upon another, are pressed by a plurality of rollers 21 by staggering manners so that the transferring surfaces meander up and down, and accordingly, the sticks passing through the gap between the belts 20, 20' are separated from each other, one by one. Then, the sticks are fed onto a counting belt 22 which accelerates the sticks so that they are further separated from each other and are therefore counted by a counter 23. Thus counted sticks are accumulated in a recessed rotary receiving part 25 in an accumulating device 24, and when the number of accumulated sticks reaches a predetermined number, they are rotated by the receiving part 25 onto a cup 26 on a transfer conveyer 27 before they are shifted onto a packing machine. Accordingly, the process can be completely automated so that no manual process is required.

Abstract: PURPOSE:To prevent the occurrence of the deformation or flaw of a rubber hose and the adhering of the heating medium to the surface of the rubber hose, etc. during vulcanization by vulcanizing the green rubber hose in a vulcanizing tank curving downward, after the outer peripheral surface of said green rubber hose has been covered with a specified heat resisting resin cover. CONSTITUTION:For instance, after an inner rubber tube 21 has been extruded on the outer periphery of a mandrel 11, said inner tube is covered with an outer rubber cover 23 with the layer of the reinforcing string 22 intervening therebetween. Thus, a green rubber hose is obtained. Next, after the outer periphery of said green rubber hose has been covered with the heat resisting resin cover 24 (e.g. nylon) which is nonadhesive to rubber hose stock and has the melting point higher than vulcanizing temperature, the rubber hose is introduced into a vulcanizing tank 15 curving downward and is vulcanized with a vulcanizing medium under high temperature and normal atmospheric pressure. Finally, the resin cover 24 is peeled and removed from a rubber hose 20, using a peeling device 18.

Abstract: PURPOSE:To achieve smooth feeding of paper by, when a roll paper holder is received by bearings, holding a portion of the roll paper delivered from an outlet opening of the roll paper holder between the roll paper holder and a roller so that the roll paper can be delivered only by rotation of the roller. CONSTITUTION:A roll paper holder 8 includes halves 8a, 8b having at both ends shanks 12 which define recessed portions in which a rotating support shaft 10 of roll paper 9 is received. The holder halves 8a, 8b are partly overlapped to define an outlet opening. With the leading end of the roll paper in the holder 8 drawn a little from the outlet opening, the shanks of the roll paper holder 8 are inserted into U-shaped grooves 13a, 18a of bearing plates 13, 18. The insertion grooves 13a, 18a and the holder shanks are so arranged and shaped as to hold the delivered roll paper between a roller 24 and the holder 8, and thus, only insertion of the holder 8 causes the roll paper to be held between the holder 8 and the roller 24. Therefore, paper can be fed accurately only by rotation of the roller.

Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To recognize the input state of a calculation formula such as a numerical value range related to a symbol and a set unit, etc., at a glance in an electronic type computer provided with a color display function. SOLUTION: For instance, in the case of performing function/√calculation processings, when a '√' key is operated in association with the input of an arithmetic formula, by displaying numerical data and function data inputted following the '√' symbol by a color different from a basic display color, it is indicated that they are arithmetic data relating to the '√' and they are processed as the data belonging to the '√'. Also, when a key 12f2 is operated, the numerical data and the function data inputted thereafter are displayed in the basic display color, it is indicated that they are not the arithmetic data relating to the '√' and they are processed as normal data.  Thus, a data range belonging to a specified symbol in the inputted arithmetic formula is recognized at a glance and arithmetically processed without the need of the operation of enclosing it by '()' and inputting it.
