Title: Anchor device for fireproof and heat insulating material layer
Inventor: IMATAKE TADAMI
IPC: F02C7/24
Filed: 1983-06-21
Abstract: PURPOSE:To certainly join a layer of fireproof and heat insulating material with the outer wall of a duct by equipping the tip of an anchor bolt, planted on the outer wall of the exhaust gas duct for a gas turbine, with an anchor cap and joining the cap with said layer. CONSTITUTION:The tip of an anchor bolt 13, planted on the inner face of an outer wall 11 of an exhaust gas duct for a gas turbine, is equipped with an anchor cap 14. Through joining the anchor cap 14 with a layer 12 of fireproof and heat insulating material, the layer 12 is stuck in a layer form to the inner face of the outer wall 11 of said duct. Due to this, even if the layer 12 is thermally expanded, the relative position between the anchor cap 14 and the layer 12 is not changed. Therefore, exfoliation of the layer 12 can be prevented.

Title: Digital operation controller for hydraulic power plant
Inventor: HAYAKAWA HIROHISA
IPC: G05B9/03
Filed: 1980-08-13
Abstract: PURPOSE:To conduct the digital operation control of a hydraulic power plant excellently by delaying the start of process control in anticipation of the time required until a reset system is restored to normal operation in a normal system when an error is generated in the reset system and a transmission request is sent to the normal system at the operation of a signal system. CONSTITUTION:The titled controller is equipped with duplicated control operation parts, system A (1-A-6-A) and system B (1-B-6-B), and an output mode switching device 7. At the normal time of both systems, systems A and B output normal signals, operate plant status through data and collate and device the outpus of both systems to control and output a coincidence data. When a normal system identifies a reset system normally at the operation of a single system, the mormal system outputs an RAM data operation request to the reset system and start the transmission of data to the RAM and the reset system stores the received data in the RAM. If a reception error is generated at the time, the reset system outputs a transmission request to the normal system, which starts the process control in anticipation of the time required until the reset system is restored to the normal operation.

Title: Fresnel lens
Inventor: IWAMURA SEISHIROU
IPC: G02B3/08
Filed: 1982-06-24
Abstract: PURPOSE:To easily release a Fresnel lens from a forming mold, by making the angle between the non-lens surface and optical axis almost equal to the angle between the non-lens surface and optical axis of the incident light in the lens. CONSTITUTION:Since the maximum pressure is applied to a triangle part abc, where no light passes through, from the forming mold when the lens is released from the mold, the mold releasing can be made easier when the triangle part abc is removed. When a Fresnel lens 9 is made to have a diagonal of 45'' and the distance from a projecting lens 12 to the Fresnel lens 9 is made 1m, for example, the incident angle theta1 of light to the outmost part of the lens becomes about 30 deg.. Therefore, the angle theta2 between the non-lens surface of the outmost part of the lens and the optical axis becomes 30 deg. and the angle between the non- lens surface closer to the center is made <=30 deg.. When such a shape is applied to a Fresnel lens, generated contracting force acts in the direction, in which the lens is released from the mold, so as to help the mold release, and, therefore, the mold release can be made easier.

Filed: 1979-08-31
Abstract: PURPOSE: To fixing the gain value controlled to the optimum level, by adding the switch, the display means and the gain manual setting means to the gain control device using the model arithmetic circuit.  
     CONSTITUTION: The deviation of the state quantity between the vibration test unit 1 and the model arithmetic circuit 2 is supplied to the gain control signal generating circuit 3. And this output signal is applied to the multipliers 5 a  and 5 b  for control of the feedback gain via integral networks 4 a  and 4 b  to receive a control to secure the deviation of zero. In this case, the potentiometers 6 a  and 6 b  provided in parallel to the gain control part are controlled to turn the display values of the display means 7 a  and 7 b  provided at the output side of the integrators 4 a  and 4 b  into zero each. In such way, the set value of the potentiometer has been replaced with the optimum gain. Accordingly, if the multiplier 5 is cut off by the switch 8 under these conditions, the gain controlled to the optimum value can be fixed.

An R-S type FF is set by a start signal of a terminal 8 by synchronizing with this word sink, and until it is reset, the counter 4 counts up a data by a clock of a terminal 5, and when it reaches a prescribed value, a carry is outputted from the counter 4 and the FF reset, and the counter 4 stops. Accordingly, the time when the FF is set corresponds to the input signal, and a PWM signal of a pulse width corresponding to the input signal is outputted from an NOR gate 7. Also, an output from a connected point 17 of an MOSTr10 and 11 becomes an opposite phase to an output of a drive amplifier 8, and becomes the same phase as the data of the input signal. This signal is outputted after its high band component has been eliminated by an LPF consisting of a coil 14 and a capacitor 15.
