Filed: 1982-02-12
Abstract: PURPOSE:To prevent excessive acceleration when the cylinder expands or contracts by  providing a check valve, a balance piston and a changeover value. CONSTITUTION:At the time when a hydraulic cylinder 2 expands, a changeover valve  19 is in the left direction, and pressurized oil of a pump 4 enters in the cylinder 2 from  an inlet port 5 through a check valve 10. At the time of contracting of the cylinder 2,  the valve 19 is in the right direction, and pressurized oil of the pump 4 is circulated to  a tank 6. On the other hand, discharged oil of the cylinder 2 flows to the tank 6  through an outlet port 3, a stationary orifice 15, a vacant chamber 14, a variable orifice  17, passages 12 and 19 and a discharge port 8. Upon this occasion, a pressure difference is caused in the outlet port 3 and the chamber 14 by an orifice 15, and the oil  pressure of the outlet port 3 presses a balance piston 13 in the right-hand direction.  The oil pressure within the chamber 14, in cooperation with a spring 18, presses the piston 13 to the left hand, and while balancing the pressing forces in the left and right  hands of the piston 13, the orifice 17 formed by a cutout port 16 and the passage 12 is  adjusted. Thus, even when an excessive load is applied to the cylinder 2, and the oil  pressure at the outlet port 3 is increased, the orifice 17 is adjusted by the movement of  the piston 13, and the cylinder 2 moves at a predetermined speed.

Filed: 1984-02-10
Abstract: PURPOSE:To produce an internal clock signal having a higher frequency than an external clock signal and also synchronous with said external clock signal, by providing a PLL circuit to an internal clock circuit. CONSTITUTION:A reference clock signal R (frequency fR) is applied to a frequency multiplying circuit 12 of an integrated circuit 11 from outside or an oscillation circuit OSC13. Then a signal S of a high frequency nfR (n: an integer) which is synchronous with the signal R is produced. A frequency multiplying circuit A consists of a PLL circuit (shown in a figure). The input signals M and N of frequency dividing circuits CNTR1 and 2 function to set the number of divisions respectively. With this internal clock generating circuit, a signal RM of a frequency of 1/M compared with the signal R is equal to a signal SN of a frequency of 1/N compared with the output signal S (frequency fS) of a VCO25 together with phases synchronous with each other. As a result, a signal S of the frequency fS equal to N.fR/M is obtained. Here fS>fR is satisfied with N/M>1. Furthermore the specific constant of an LPF24 is set variable to ensure an action corresponding to a wide range of external clock frequencies.

Title: Delivery control method for powdery material
Inventor: NOMURA KOICHI
IPC: B65G65/42
Filed: 1985-02-08
Abstract: PURPOSE:To enable delivery of powdery material to be accurately controlled by setting a horizontal conveyor just beneath a discharge outlet of a tank with a certain space apart from the outlet when the conveyor is at rest so as to enable the powdery material to stay forming an angle of repose between the discharge outlet and the conveyor. CONSTITUTION:When a belt conveyor 10 is at rest in a conveyor powdery material 3 stays forming an angle of repose between a discharge outlet 5 and the conveyor. This configuration prevents the powdery material 3 from naturally falling down which is followed by its flow-out from an outlet 5 of a tempering tank 1. However, when the conveyor once starts out of this statical condition. The powdery material 3 that stays there forming the angle of repose is conveyed in succession. This cause the quantity of the powdery material 3 equivalent to the quantity transferred to fall down and to be delivered in succession. Accordingly, it is relatively simple to control the conveyor so as to regulate accurately discharge of the powdery material 3 in the tank by merely controlling the quantity of the powdery material 3 to be transferred. This configuration enables delivery of the powdery material 3 to be controlled as desired.
