Title: Phaselocked loop circuit
Inventor: KADOWAKI MAKOTO
IPC: H03L7/10
Filed: 1991-03-18
Abstract: PURPOSE:To prevent a jump of a frequency of a VCO at the restoration of an input clock by using a N/2 frequency division pulse of the VCO so as to keep an output of a coupling circuit to a required control voltage level at the clock input interruption. CONSTITUTION:When an input interruption detection circuit 1 detects a clock interrupt, A phase comparator circuit 4 segmenting a signal with a pulse of 1/N frequency division via a 1/N frequency divider circuit 2 segments an output of a VCO 9 by using a pulse of N/2 frequency division by a N/2 frequency divider circuit 10. On the other hand, a phase comparator 5 inhibits the set of an FF 21 at the interruption and uses the N/2 frequency division pulse of the VCO 9 to repeat the inversion of a FF 21. Thus, a duty of an input pulse to a coupling circuit 8 is close to 50% and an output level of the circuit 8 reaches a level at which the VCO 9 outputs a center frequency and jump of an output frequency is prevented when the input clock is restored.

Title: Washing machine
Inventor: TANI KAZUTOSHI
IPC: D06F33/02
Filed: 1990-03-30
Abstract: PURPOSE:To execute proper washing without fail and to prevent damage for cloth by detecting a bath ratio considering the cloth quality of putted-in laundary as well in washing and rinsing processes. CONSTITUTION:When a pulsator 5 is turned off and stirring is stopped, foam raised upward to the surface of water and the output of a foam detector 17 is balanced. In the case of B that the amount of water is proper to the capacity of laundry, time T2B to reach balance is determined by experimentation. In the case of C, a strong water current is generated since there is no laundry near the water surface of a washing tank, and much foam is generated near the water surface. Therefore, it takes a long time for the foam to move on the water surface, and since the foam generated at the lower part of the washing tank received the much trouble for raising caused by the foam near the water surface, time T2C for the output of the foam detector 17 to be balanced is made longer in comparison with the T2B. Thus, based on time T2 for the output of the foam detector 17 to be balanced, a microcomputer detects the bath ratio and this is compared with a bath ratio to the T2B. When the amount of water is a little to the laundry, a command is outputted to a water feeding mechanism 11 and water feeding is automatically executed.

Title: Allocation setting method of sheet thickness measuring position and lip position in extrusion
Inventor: OTA TOMOYA
IPC: B29C48/08
Filed: 1990-03-30
Abstract: PURPOSE:To easily perform allocation setting of both thickness measuring position and lip piece at high precision by allotting and setting the correspondent relation of the thickness measuring position in the width direction of a plastic sheet in the place for measuring sheet thickness and a plurality of lip pieces on the basis of an expression shown in an experimentally obtained rational function. CONSTITUTION:Thickness in the width direction of plastic in the place for measuring sheet thickness is measured. The relation of relative position of both the position Xi of a lip piece and the thickness measuring position Xi in the width direction receiving the effect of this lip piece is experimentally obtained and approached by a rational functional expression. In the expressions (1) - (3), the position data X0 - Xn are already known and the neck-in amount X0 is measured at every time for measuring thickness because a thickness measuring instrument is moved in the width direction of the plastic sheet from position 0. When these values are obtained, calculation is performed in the order of x1, x2, x3,.... Since the thickness measuring positions correspondent to the position data X1, X2, X3,... of lip pieces are calculated, it can be easily understood that the thickness measuring position corresponds to any lip piece.
