Title: Orifice-type flow rate-measuring apparatus
Inventor: AKITA HOZUMI
IPC: G01F1/42
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce costs and measure a flow rate highly accurately by using a low flow rate orifice of a small diameter and a high flow rate orifice of a large diameter thereby measuring the flow rate in a wide range. SOLUTION: Normally, a differential pressure transmitter 18 measures a flow rate differential pressure by a low flow rate orifice 12 or a high flow rate orifice 13 via either of orifice switch valves 16 and 17. A valve-switching control means 19 suitably selects and connects the orifice 12, 13 to the transmitter 18 in accordance with an output of the transmitter 18. An optimum differential pressure can thus be taken irrespective of whether the flow rate is large or small. The flow rate can be measured highly accurately with the use of one differential pressure transmitter 18. Particularly, orifices 12, 13 are inexpensive in comparison with the differential pressure transmitter 18, and therefore costs can be remarkably reduced if a count of objects to be measured in increased.

Title: Disk reproducing device
Inventor: SHIOZAKI YOSHIHIKO
IPC: G11B19/28
Filed: 1983-01-10
Abstract: PURPOSE:To control a reproduced synchronizing clock and the number of revolution of a disk by counting minimum and maximum edge lengths Nmin and Nmax by the reproduced synchronizing clock, and detecting an edge interval longer than an Nmax clock when a following edge comes before an Nmin clock. CONSTITUTION:When the number of revolution increases (decreases), a VCO6 outputs a clock synchronizing with a pulse train from an edge detector 3 within the locking range of a phase-locked loop 14. This clock leads (lags) the clock of a reference clock oscillator 9 in phase and decreases (increases) the number of revolution through a phase-voltage converter 10. When the loop 14 enters a step- out state to increase (decrease) the number of revolution, a minimum (maximum) pulse length detector 7(8) increases the oscillation frequency of the VCO6 so that the minimum (maximum) pulse interval of the pulse train from the detector 3 is larger than the Nmin clock (Nmax clock) by the clock of the VCO6. This frequency becomes larger (smaller) of the clock of an oscillator 9 and the number of revolution is increased (decreased) by converters 10 and 11 and a driving circuit 12 to a number of revolution that the loop 14 synchronizes with.

Title: Two-way switching circuit
Inventor: KITANO JIYUNJIROU
IPC: H01L29/74
Filed: 1978-01-17
Abstract: PURPOSE: To improve the degree of integration as well as to realize the cost reduction by providing the means which short-circuiting transiently between the P-gate and the cathode of one SCR when the transient voltage is applied to two units of SCR connected in parallel reversely.  
     CONSTITUTION: The 4-terminal SCR1 and 11 which share the n-base are connected in parallel to each other reversely via diode 4 and 14. When the potential of terminal C 1  has a sudden rise to terminal C 1 , the current charging the capacity of the 2nd junction (between n-base G n  and P-gate GP 1 ) of SCR1 tends to flow to cathode K 1  from GP 1  to cause the misignition of SCR1. At the same time, the current charging the capacity of the 1st junction (between GN and anode A 2 ) of SCR11 drives the base of npn-transistor Tr2 via diode 3 to secure the low resistance between the collecter and emittor of Tr2. As a result, SCR1 has no ignition. Thus, Tr2 features the function to give the transient short circuit between GP 1  and K 1  at the application time of the transienttn voltage.
