Title: Manufacture of thermoplastic resin sheet or film and device therefor
Inventor: FUJII JUNJI
IPC: B29C47/88
Filed: 1990-05-28
Abstract: PURPOSE:To manufacture a sheet without haze stripes, uniform and of superior transparency and surface gloss properties by setting the inclined angle to the vertical lines of respective slit walls by a specified angle when a film-like thermoplastic resin is quenched and using a slit with a slit interval narrowed toward the downflow direction of cooling liquid. CONSTITUTION:Thermoplastic resin in the melting state is extruded out of a T-die 1, and the extruded film-like thermoplastic resin 2 is introduced into a slit 3 having slit walls where the quenching liquid flow down. The inclined angle to the vertical lines at respective slit walls is more than 0 deg. to less than 30 deg., and the slit 3 with slit interval narrowed toward the downflow direction of cooling liquid is used. When theta is beyond 30 deg., the flow of cooling liquid in the slit 3 is slowed down, and as a molten sheet reaches the residual water, cooling effect is worsened and boiling mottles are generated, which is not preferable. On the other hand, when theta is 0 deg., the cooling liquid is dropped by its gravity in the slit, and the flow rate gets faster at the lower section of slit and the apparent volume is reduced to make the cooling of sheet uneven and insufficient and generate haze mottles.

Abstract: PURPOSE:To improve the measuring accuracy for softening temperature and incipient fluidization temperature by obtaining the temperature based on the intersection between a straight line which is approximate to the curve section at the minimum gradient and a straight line which is approximate to a curve section including a point where the amount of piston movement leaves by a specified value. CONSTITUTION:A control circuit 14 stores a pair of data of fluidization curves based on the amount of piston movement that is detected with a potentiometer 11 and the test temperature detected with a temperature detector 12. Then, the intersection between a straight line which is approximate to the curve section including a point where the minimum gradient is formed viewed from the higher temperature side and a straight line which is approximate to the curve section including a point where the amount of the piston movement leaves by a specified value DELTAS is obtained. Then, the test temperature corresponding to the intersection is determined as the outflow starting temperature. The curve section where the minimum gradient is formed viewed from the lower temperature side is detected, and the softening temperature is determined by the same way. Thus, the measuring accuracy when the softening temperature and the outflow starting temperature of a sample are automatically determined can be improved.

Abstract: PURPOSE:To prevent the switching point of a VTR from being displayed as a video by providing a means which can set plural vertical video blanking periods. CONSTITUTION:The vertical video blanking preparing device of a picture display device counts a horizontal synchronizing pulse from a vertical synchronizing signal, and forcedly operates the vertical video blanking when the pulse count value reaches a prescribed value (n).

Further, the shoulder sections contiguous to the crown section on both sides of the latter has a radius Rs of curvature, and the tread section composed of the crown section and the shoulder sections has a width Wt. In this arrangement, the dimensions of the above-mentioned sections are set so that the following formulas may be satisfied: 2.5<Rc/Wt<5.0, 0.5<Wc/Wt<0.75, 1.1<Rs/Rc<2.0. With this arrangement, the distribution of ground contact pressure of the tire during running is made to be uniform, thereby it is possible to prevent eccentric abrasion.

Abstract: PURPOSE:To control phase difference between duplex operating clock generating parts and that with an absolute phase within a constant range by providing a means to prohibit the reset of a counter at a spare side with a reset pulse from a side in current use unless the phase difference exceeds a prescribed range. CONSTITUTION:The circuit is comprised in such a way that prohibiting pulse generation circuits 101 and 102, and AND gates 103 and 104 are provided newly, and the counter of its own system can be prevented from being reset with the reset pulse from the reset pulse generation circuit of another system when the phase difference between the counter output of its own system and the counter of another system is within a range set in advance, respectively. In other words, since the phase difference between both systems coincides with that at the trailing edges of output of both systems, the reset pulse from another system is prohibited to be inputted within a certain range where the trailing edge of the counter output of its own system is set as reference in its own system. Thereby, it is possible to suppress the output phase difference of two counters within the constant range, and to suppress deviation with the absolute phase within a similar range.
