Title: Combustion amount detecting device for liquid fuel burner
Inventor: MORI KEIICHI
IPC: F23N5/24
Filed: 1988-03-31
Abstract: PURPOSE:To enable the detection of an accurate combustion amount of a device equipped with no fuel pump, by providing a fuel measuring part to compute a remaining amount of fuel by means of a signal outputted from a weight sensor to measure the weight of a fuel tank and a controller containing a fuel amount computing part to compute a combustion amount of a burner by means of a change in a signal outputted from the fuel measuring part. CONSTITUTION:A weight sensor 19 is mounted to a base plate 1 located below a fixed tank 2, and measures the weight of the fixed tank 2 having a free end (c) and a cartridge tank 7. A fuel amount is computed by a fuel measuring part 21 of a controller 20 from the weight by means of a signal outputted from the weight sensor unit 19, and a signal is outputted to a combustion amount computing part 22 and a remaining time computing part 23. When a burner 14 effects combustion at a specified combustion rate, the remaining fuel determined by a fuel measuring part 21 is gradually decreased. From the degree of the decrease, a combustion amount of a burner 14 is determined. The remaining time computing part 23 computes the remaining time (hours) when the fuel tank reaches an emptied state, and when a remaining combustion time is reduced to a value lower than a specified value, a control signal announcing the necessity for a fuel refilling and the stop of a combustion is outputted.

Abstract: PURPOSE:To prevent double recording or the erasure of information accidentally from being generated, by detecting a state where an elliptic optical spot and an almost circular optical spot do not exist on the same track by a signal to detect the double recording when it occurs. CONSTITUTION:An almost circular beam L and an elliptical beam M are formed on a disk 1 by laser beams from light sources 1 and 2. In such a case, when data is recorded on a data area, a random signal is recorded by a signal 25-a, and the data is recorded on the data area by a driving signal 21-b. At this time, an electrical signal is supplied from an optical detector 15 to which the reflected light of the optical spot L for recording and reproduction is introduced to a lower end envelope detection circuit 17. If the positions of the spot M and the spot L are deviated and both spots do not scan the same track, a lower end envelope output 17-a is detected at the circuit 17, and a signal 22-a is supplied to a microcomputer 21. When the signal 22-a is detected by the microcomputer 21, by turning OFF the control signals 21-c and 21-b of the light sources 1 and 2, it is possible to prevent the double recording and the erasure of the information from being generated.

Title: Microprocessor
Inventor: KAWAHARA MASABUMI
IPC: G06F11/30
Filed: 1987-04-01
Abstract: PURPOSE:To provide a microprocessor with a self-diagnosis function without requiring an external circuit by stopping data setting from a CPU to a register at the time of generating abnormality in the CPU, and detecting an abnormality detecting signal in accordance with the contents of the register. CONSTITUTION:When the CPU 8 is normally operated, prescribed data, e.g., '0' are transferred to the register 4 at a fixed period. The register 4 starts increment from the '0' and overflows its contents at FFH 0, but the CPU 8 sets up '0' again prior to said overflow. Thereby, a flag 5 is not set up and the state of a pulse output port 7 is not changed. When the CPU 8 is not normally operated due to the stop of a system clock or the runaway of a program, data are not transferred from the CPU to the register 4. Consequently, the contents of the register 4 reaches FHH and outputs an overflow signal at the time of FFH 0, so that the flag 5 is set up and a level inverting circuit 6 inverts the output of the port 7.

Abstract: PURPOSE:To prevent noise and entering of dust to a disk storage device with simple structure by projecting a rib whose apex is in press contact with other ring face along one ring face of a case and a cover and interposing a gasket between other parts than the ring shaped rib air-tightly. CONSTITUTION:A rib 21 is projected along a ring mating face MF of a case 10 and a cover 20 tightened mutually on the ring mating face MF, an apex of the rib 21 is in press contact with other ring face when the case 10 and the cover are tightened, a gasket 40 is interposed air-tightly between other parts than the rib of the ring mating face MF.

Furthermore, the degree of compressing the gasket 40 is managed accurately depending on the height of the rib 21 and no excess pressure is exerted, then the deterioration in the gasket 40 is decreased. Thus, noise and entering of dust to a disk storage device are prevented with simple structure.
