Title: Flame detector
Inventor: YAMAMOTO KOJI
IPC: F23N5/08
Filed: 1987-06-19
Abstract: PURPOSE:To improve the reliability of set values and to eliminate a failure in ignition or extinction by setting decision voltages in every burner states. CONSTITUTION:A flame detector 15 detects a burner flame. The detected flame is led to a detector board 20 through a fiber cable 16. This optical fiber cable 16 is connected directly to a photoelectric converter 17 provided in the detector board 20 and the detected light is converted here into an electric signal, which is inputted to a decision board 18 to decide the flame. The decision board 18 knows a flame signal outputted from another flame decision board through a communication board 19. In this case, flame presence/absence decision voltages are set by burner conditions to minimize the influence of variation of the burner conditions of flame decision making.

Filed: 1987-06-17
Abstract: PURPOSE:To prevent a fault caused by a specific processor by selecting (m) pieces of processors at random out of (n) pieces of processors to read out clock information when the clock of a processor shows a prescribed time and to control the clock based on the time of (m) pieces of processors. CONSTITUTION:When a block showing the time of processors 301-305 shows a prescribed time, (m) pieces of processors are selected at random out of those processors 301-305 and the clock information on these processors are read out. Then the clocks of processors 301-305 are controlled based on said (m) pieces of processors. As a result, the clocks of all processors 301-305 are controlled so that they point out the same time within a certain synchronizing accuracy range. Thus it is possible to prevent the fault of a specific processor from causing a fatal fault to a multi-processor system.

Title: Switching type stabilized power supply of x-ray plant
Inventor: KAWAMURA KAZUMITSU
IPC: H05G1/32
Filed: 1985-07-12
Abstract: PURPOSE:To stabilize the output voltage of a switching type stabilized power supply even for large load variation by changing the value of a dummy resistor connnected in parallel with an inverter drived by the switching type stabilized power supply according to X-ray exposure condition. CONSTITUTION:A switchint type stabilized power supply drives an inverter which operates an X-ray plant. At this time, a control circuit 13 compares a detected value of a resistor 17 for current detection with a value determined from the outputs of a tube voltage setter 14 and a tube current setter 15 and controls a transistor 10 with a series dummy resistor 9, which is connected with an inverter 11 in parallel, so that both said values may become equal. And when the preduct of the tube voltage and tube current becomes smaller, the dummy resistor value is made larger and, on the contrary, when it becomes larger, the dummy resistor value is made smaller. Therefore, at the time of heavy load, the capacity of the power supply can be reduced by reducing the current flowing through the dummy resistor and besides output voltage regulation can be made small.

Title: Hammer for piano and its manufacture, and piano
Inventor: KITAJIMA RIICHI
IPC: G10C3/18
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent the tip part of a hammer wood from deforming when felts are fitted to the tip side. SOLUTION: When the hammer felts 10 and 12 are wound in with a strong force, large pressure is applied to the tip part 8, but the tip part 8 of a composite material 6 for the hammer wood neither curves nor breaks even if the tip part 8 is thinner than a base part 9 since the tip part is formed of maple lumber plywood 4 having higher density than the base part 9. Therefore, the yield of the manufacture can be improved. Further, the whole hammer wood is not made of the maple lumber plywood having the high density, but uses the high- density maple lumber plywood partially only at the tip part 8 which is formed thinnly, so nearly no influence is exerted on string striking characteristics of a hammer using the hammer wood. Therefore, a piano having this hammer incorporated can have the same characteristics as usual.
