Title: Manufacture of vinyl chloride group resin coating material
Inventor: TAKAHIRA AKITOSHI
IPC: B29C51/00
Filed: 1982-02-25
Abstract: PURPOSE:To manufacture the vinyl chloride resin coating material having excellent heat seal property, sliding property and blocking resistance with high productivity by a method wherein an emulsion containing vinyl chloride group resin is applied to a base material and the base material is heated, dried and cooled and wound in a roll shape. CONSTITUTION:The emulsion containing vinyl chloride group resin is applied onto one surface or both surfaces of the base material, and the base material is heated and dried and cooled at the normal temperature and wound in a roll shape. Paper, a plastic film, metallic foil, cloth, a nonwoven fabric or these composite bodies or the like is cited as the base material used. A copolymer in which the composition (in weight ratio) of a monomer of vinyl chloride and ethylene is 40-95:5-60 or its denatured substance is cited as vinyl chloride group resin. Less than 40wt% of vinyl chloride is undesirable because the blocking resistance of a film lowers and not less than 90wt% of vinyl chloride because the flexibility and heat seal property of the film lowers.

Title: Pulley for elastic belt
Inventor: MIZUNO TOMOSANE
IPC: B65G23/04
Filed: 1995-02-20
Abstract: PURPOSE: To prevent coming-off and riding-over of an elastic belt without increasing a diameter of a flange by providing the flange at both ends of a pulley having a projection at its center and providing a groove on the inside of the flange. CONSTITUTION: A pulley 3 has a projection at its center, and a flange 7 is provided at both ends of the pulley 3. A groove 8 is provided on the inside of the flange 7. When synchronization between the pulley 3 and an elastic belt 2 is lost and the elastic belt 2 is deviated toward an end of the pulley 3, the elastic belt 2 drops its end into the groove 8 due to its tensile force. When the end of the elastic belt 2 reaches the flange 7 finally, a distance between the end of the belt and an outside diameter section of the flange increases and an angle formed by the elastic belt 2 and the flange 7 becomes sharper. As a result, apparent height of the flange 7 when viewed from the elastic belt 2 increases so that riding over and riding across the flange of the elastic belt 2 does not occur easily.

Title: Mos device for analog circuit
Inventor: HADIDI KAIRORA
IPC: H03F1/22
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To reduce parasitic capacity being generated by the wiring between devices, and to miniaturize a circuit itself by inclining the concentration of the ion implantation of a channel for connecting a source to a drain continuously or in steps from the source to the drain. SOLUTION: Channel length L between a source S and a drain D is divided into L/2 and L/2, and the concentration of ion implantation in one L/2 is allowed to differ from that in the other. When more ions are implanted at a source side, a threshold voltage at the source side is increased as compared with that of the other L/2. An obtained transistor is equivalent to two transistors of the channel length L/2 with a common gate being connected in series. Since the threshold voltage is different in the two transistors, both of them can be operated in a saturation region by appropriately adjusting bias, thus reducing effective channel width, and hence increasing effective gain.

Title: Acceleration/deceleration controller
Inventor: KOBAYASHI YUKIHIKO
IPC: G05B19/416
Filed: 1988-02-15
Abstract: PURPOSE:To set the beginning of the rise of acceleration and that of the fall of deceleration to a large time constant so as to avoid the sudden change of acceleration at the time of acceleration and deceleration by switching the time constant of linear acceleration and deceleration from tau1 to tau2 which is smaller than tau1 is the middle of acceleration and deceleration. CONSTITUTION:At the time of acceleration, a feed rate F, a move quantity S and a sampling period T, which are necessary as a command, are given to a pulse distributor 1, and the pulse generator 1 executes pulse distributing operation based on the inputted move quantity S, generates the move quantity DELTAS of a one sample time so as to send it to a switching circuit 4. The switching circuit 4 selects a first direct acceleration deceleration circuit 2 so that the move quantity S is sent to the circuit 2 from the beginning of acceleration to a constant time t1. When t1 passes, the switching circuit 4 selects a second linear acceleration and deceleration circuit 3, sends the move quantity DELTAS and controls linear acceleration and deceleration with the time constant tau2 which is smaller than tau1. Consequently, an acceleration control characteristic turns into a tertiary curve approximate acceleration characteristic. The same occurs at the time of deceleration in the same way as an acceleration time.

Title: Water disposal
Inventor: UMAGOE SHIYOUJI
IPC: C02F3/08
Filed: 1980-03-12
Abstract: PURPOSE: To offer a new water disposal process which enables easy separation of adhesive sludge, by forcibly desiccating small carriers onto which active sludge from a fluid layer is adhered, and then drying the small carriers in a drier where a material to be dried is adhered to and split from other carriers.  
     CONSTITUTION: Active sludge adhered onto small carriers (a) is used for water disposal. When an excessive amount of the active sludge is adhered onto the carriers, a part of the carriers and a part of water to be disposed are extracted and forcibly desiccated by a desiccator 5. The material to be dried is thereafter adhered onto other carriers A at a sludge supply portion 6c, fed to a packed layer 6a, and carried to a collecting portion 6d by a screw conveyer 6b, while the small carriers (a) are introduced to a drier 6 where the material to be dried will be split from the carrier A. A large amount of the sludge is adhered onto the carriers A and dried, so the separation can be done very easily. The small carriers (a) are returned to the fluid layer 2. Thus, the adhesive sludge can be rationally separated from the small carriers, and the water disposal can be done effectively.
