Title: Spring control device
IPC: E05F1/10
Filed: 1942-01-22
Abstract: 553,011. Springs &c. FISHER, C. J. Jan. 22, 1942, No. 918. Addition to 545,720. [Class 108 (iii)] [Also in Group XXV] A spring control device for doors &c. comprises three relatively rotatable discs 10, 11 12, mounted on a common pivot 13, the outer discs having angularly spaced radial arms 17, 18 while the middle disc has a radial arm 19 in the angle between 17, 18. A curved rod 21 fixed to 18 and sliding through 17, 19 acts as guide for two springs 23, 24 of different strengths, of which 23 abuts on 17 & 19 while 24 abuts on 18 & 19. A hole 14 in the disc, 12 houses a ball 15 of greater diameter than the thickness of the disc, and the discs 10, 11 have each a recess 16 with one or other of which the ball engages to lock the corresponding disc to disc 12. When the arms 17, 18 are moved towards each other by the movement of a door &c. one of the outer discs moves with disc 12 to compress opening 23. When the ball 15 comes opposite the recess 16 in the other outer disc, it enters same and locks the spring 23 in the compressed state, while further movement of the discs compresses the spring 24. During the closing of the door, the spring 23 acts first, and the final closing is effected by 24.

Title: Improvements in and relating to pneumatic vibrating machines employed in fatigue testing materials
IPC: B06B1/18
Filed: 1949-01-13
Abstract: 656,447. Fatigue testing of materials. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 13, 1949, No. 988. Convention date, Jan. 21., 1948. [Class 106 (ii)] A pneumatic vibrator of the type described in Specification 632,596, is provided with means for maintaining the amplitude of vibration constant. A reed 1 to be tested supports a piston 2 driven by compressed air from nozzles 3, and a triangular portion 5 arranged to obstruct an air port 4 in its centre position, and to uncover progressively the port 4 on either side of its centre position. Associated with the air supply to the vibrating reed is a control valve 13 actuated by a spring-compensated diaphragm 11 in a chamber 8. The diaphragm 11 divides the chamber 8 into two compartments 9, 10. Air is supplied via a constant pressure regulator 6 to the lower compartment 10 and then through a valve 14 to the nozzles 3. A further supply of air is taken via a branch valve 7 to the upper compartment 9 and the regulating air port 4. In operation, increased amplitude of vibration beyond the normal amplitude results in the port 4 being uncovered for longer periods of time causing a slight drop in the pressure in compartment 9, causing the diaphragm to move upwards, closing slightly the valve 13 and reducing the air supply to the nozzles 3. Reduced amplitude of vibration results in the port 4 being covered for longer periods and causes an increased pressure in compartment 9, causing the diaphragm 11 to move downwards opening the valve 13 to increase the air supply to nozzles 3. In a modification shown in Fig. 4, regenerative control is applied for a more sensitive control by connecting the branch valve 7 into the air conduit after the chamber 10 instead of ahead of it as previously shown. In operation, decreasing vibrational amplitude increases the pressure at port 4 and in the upper compartment 9 as before and movement of the diaphragm and valve 13 to increase the pressure in compartment 10 and the nozzles 3 also applies a further increase to compartment 9 via the valve 7, thus providing regeneration to compensate amplitude errors more quickly. A regenerative decrease of pressure in chamber 9 is similarly caused by increased vibrational amplitude. In this modification, the constant pressure regulating valve 61 may be dispensed with.

Title: Control system for rotor stress prediction turbine
Inventor: MATSUMOTO HIROSHI
IPC: F01D21/00
Filed: 1979-01-08
Abstract: PURPOSE: To enable quick starting and quick load change, by predicting the thermal stress of a prescribed part of a turbine as to an assumed value of a control parameter and comparing the thermal stress with an allowable value to determine an optimal control parameter.  
     CONSTITUTION: In starting, the rate of speed increase is used as a control parameter. In loaded operation, the rate of load change is used as a control parameter. The thermal stress of prescribed parts such as first stage rear labyrinth packing parts 1, 2 of turbines 200, 300 is predicted as to an assumed value of the control parameter and compared with an allowable value to determine an optimal control parameter. In determining the control parameter by a thermal stress prediction control system 100, future stress values corresponding to two rates of speed increase or two rates of load change which are prepared beforehand are predicted. Such a rate of speed increasing rate or load changing rate is determined from two maximum stress values in the range between the predicted future stress values that the stress coincides with a limit value.

Title: Higher harmonic filter
Inventor: HASEGAWA ATSUSHI
IPC: H03H19/00
Filed: 1980-01-07
Abstract: PURPOSE:To obtain a higher harmonic filter which operates accurately to an integer-fold frequency compared with the basic frequency and has an appropriately high Q with a high speed of response, by supplying a frequency obtained by multiplying the basic frequency as the clock of the N-path filter. CONSTITUTION:For the input signal, the basic frequency is obtained through the basic frequency recognizing circuit 1 and then multiplied by the multiplier 2 to be sent to the clock control circuit 3. Thus the ratio of division or the duty ratio of the pulse is varied to control the N-path filter group 4. For the filter group 4, the central frequency of the pass band depends on the frequency of the clock pulse. Then the clock pulse of double the higher harmonic component to be detected, i.e., the basic frequency is set to f0. Thus the clock pulses of 4f0 and 6f0 are supplied to the switches S1, S1', S2, S2'...Sn, Sn' for the detection of the 2nd and 3rd higher harmonic components respectively.

Title: Solid-state image pick-up element
Inventor: HAMAZAKI MASAHARU
IPC: H04N5/359
Filed: 1989-01-06
Abstract: PURPOSE:To restrain a brooming from occurring by a method wherein a reset transistor is made conductive during the accumulation of a photo signal charge excluding the reset time. CONSTITUTION:With the exception of a reset time, electrons generated by incident light are collected in an aluminum electrode layer 3 conforming to the potential gradient in a photoconductive film 1 while holes are to be collected in a transparent electrode 2 side. Accordingly, any excess charge generated by intensive light from a high brightness light source is to be overflowed into a wiring 17 through the intermediary of the layer 3, a conductive region 18, a gate electrode 7 and a source region 4, a drain region 5 of a reset transistor. Normally, when the film 1 is not impressed with any voltage at all, the potential in the film 1 is leveled to cause a brooming. However, in this solid-state image pick-up element, the reset transistor is made conductive to provide the film 1 with potential gradient so that the brooming may be restrained from occurring.
