Title: Specular surface detector
Inventor: SAKATA HARUYASU
IPC: G11B7/085
Filed: 1989-02-21
Abstract: PURPOSE:To obtain a specular surface detector to relatively easily and surely detect an unrecorded area by discriminating the level of a tracking error signal low-band component after opening a tracking servo loop. CONSTITUTION:When an information read spot enters into an unrecorded area, the output of a demodulating circuit 8 is not generated. When such a state is detected by a control circuit 6, it instructs a loop switch 2 to open a tracking servo loop 5. At such a time, an objective lens is returned to the neutral position. With respect to the unrecorded area, the information read spot does not intersect tracks and the level of a tracking error signal A is about zero, and the noise due to flaws or the like of the disk surface is eliminated by an LPF 11 when occurring. An output B of the LPF is subjected to full-wave rectification by an absolute value circuit 12, and an output C is converted to a DC signal D by an LPF 13 and is compared with a reference level VTH by a comparator 14, and the high level is outputted when the output C is lower than the level VTH. Thus, the circuit 6 detects abnormality of read to output the control signal which returns a pickup to the initial position.

Abstract: PURPOSE:To magnify, reduce, rotate, etc., a shape displayed on a screen without using an operation menu by dividing a display screen into plural areas and selecting the operation commands for shift, rotation, etc., of a three-dimensional shape with selection of those divided areas. CONSTITUTION:A shape display screen doubles as a shape operation screen. Then, the shape operation screen is divided into plural areas and selected by an operator for operation of a shape with no display of a menu. For instance, the shape display screen is divided in regard of the magnification/reduction (scale) of a shape, the right/left rotation or the shift, i.e., rotation (beta), shift (left) and shift (right) of the shape, the upper/lower rotation of the shift, i.e., rotate (alpha), shift (up) and shift (down), and an XY plane, a YZ plane, and ZX plane respectively. Then the shape operation is carried out on the screen where a three-dimensional shape is displayed. Such a shape operation requires no menu display and therefore the available area of the display screen is increased.

Abstract: PURPOSE:To simplify a control program, to reduce the capacity of a ROM and to improve the maintenance property of the ROM capacity by reading out the control program of a general-purpose input/output bus control means via a multi-staged boot. CONSTITUTION:In the start processing state of a CPU 1, a boot program is taken out of a magnetic disk device 9 and loaded into the memory 6 of a general-purpose input/output bus control means 100. Then the boot program is executed in the means 100, and a control program which is originally used by the means 100 is loaded into the memory 6 from the device 9. The control is shifted to the loaded control program. Therefore the control program which is registered into a ROM 2 is just required to have a limited function to load the boot program into the memory 6 of the means 100 via the device 9. Thus it is possible to simplify the control program registered into the ROM 2, to reduce the capacity of the ROM 2, and to improve the maintenance property of the ROM capacity.

Abstract: PURPOSE:To improve the operability and the safety, by retaining an armature of an electronmagnetic valve in the attracted state even when a pressing force on a knob is released immediately after a pilot burner is ignited, and causing the armature not to be attracted if the pilot burner is not ignited. CONSTITUTION:When the pilot burner is ignited, a thermocouple 28 is heated, and its output is gradually increased, and the change of the output is detected by a differential circuit 31, and is compared by a comparator 33. For a prescribed period after the start of heating, since the output of the thermocouple 28 is gradually increased, the output of the comparator 33 becomes a L level to turn a transistor 25 on, and a current is passed to a coil 27 so that the armature is kept attracted. After a prescribed period, the comparator 33 is reversed, and while the transisters 25, 23 are turned off, by the output of the thermocouple 28 a current is passed to the coil so that the armature is kept attracted. If the pilot burner is not ignited, the transistor 25 is not turned on, and therefore a raw gas would not be discharged.

IPC: H04N5/378
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To obtain an image-pickup device with excellent convenience for use that has a high degree of freedom in signal processing, where a shutter chance is rarely missed by allowing a control means of the device to write sequentially a 1st digital signal to idle areas of a memory means at a depressing of a shutter button and to user a signal processing means to conduct signal processing sequentially when no 1st digital signal is written in the memory means. SOLUTION: When a control circuit 9 detects it that a shutter button 10 has been depressed, in the case of picking up a still image by the image-pickup device, image signals by one image pattern outputted from a CCD 2 are written in a memory 6 via an amplifier circuit 3, an A/D converter 4, a memory control circuit 5 and a bus 11. The written image signal is processed by a signal- processing circuit 7. In the case that the shutter button is depressed on the way of the signal processing, the signal processing is stopped and the picked-up image signals in this case are written in the memory 6. The capacity of the memory 6 is selected, so that the memory 6 is able to store image signals of a plurality of image patterns.
