Title: Multimagnet electric generator employing vertical motion of wave
Inventor: MANABE YASUHIRO
IPC: H02K35/00
Filed: 1979-05-30
Abstract: PURPOSE:To easily obtain electric energy on the sea or the like without positional restruction, by directly utilizing the reciprocation of waves or the like for the relative reciprocation of an electricity generator. CONSTITUTION:An electricity generator 8 has a float 9 on the sea. A cylindrical body 5' is vertically placed in the sea so that the top of the body is positioned slightly over the top of the float 9 by a float 11 and a weight 12 for balance. Even if waves come to the generator, the cylindrical body 5' is kept almost vertical by the interaction of the float 11 and the weight 12 but the other float 9 responds with high sensitivity to the vertical motion of the waves. At that time, a coil 7 in the cylindrical body 5' and a magnet 3 around a shaft 2 are vertically moved relatively to each other to cause an electromotive force across the coil 7. The force is applied to a load 15. Electric energy is thus easily obtained from wave motion energy.

Filed: 1991-03-29
Abstract: PURPOSE:To limit degradation in a range for the redundant degree of eyes in the case if image compression by quantizing a DCT coefficient by using an optimum quantizing table to the resolution characteristic of an output equipment to extend and output a sampling ratio or an image. CONSTITUTION:The three primary color data of R, G and B inputted from an image input part 17 are transformed to Y, Cr and Cb by a color transformation part 1. The Y is a luminance component and the Cr and the Cb are chromaticity components. While considering the redundant degree of eyes, there is no trouble even when the resolutions of the Cr and the Cb are lowered. Therefore, a sub sampling part 2 slightly lowers the ratio of the resolution to the latter two components. Corresponding to it, 8X8 DCT coefficients are obtained by DCT parts 4, 5 and 6. Next, these data are supplied to quantizing parts 7, 8 and 9 and quantized according to the prepared quantizing table. The outputs are encoded by huffman encoding parts 10, 11 and 12. The outputs of the encoding parts 10, 11 and 12 are turned to compressed data by serially arranging the data for each color in the order of blocks at a parallel / serial conversion part 13.

Title: Single-chip microcomputer
Inventor: NIIJIMA SHINJI
IPC: G06F1/06
Filed: 1990-03-16
Abstract: PURPOSE:To eliminate the need for the wait time for clock switching and to improve the processing ability of a CPU by stopping a main system clock oscillation circuit automatically after a main clock is switched to a subclock. CONSTITUTION:When a clock signal 103 is switched from the main clock 102 to the subclock signal 101, the CPU sets a selector flag 3 to '1' and a synchronism control circuit 6 synchronizes the main clock signal 102 and subclock signal 101 with each other, so that a synchronizing signal 121 rises from '0' to '1'. Then when a selector signal control circuit 8 outputs a selector signal 12, the selector signal 112 becomes '1' and a selector 7 finishes the switching. On the other hand, since an oscillation control flag signal 105 and a selector flag signal 116 are both '1' the synchronizing signal 121 rises, the output of an AND gate 22 becomes '1', and an oscillation control signal 120 goes up to '1', so that a main system clock oscillation circuit 5 stops oscillating. Consequently, the time required for the switching is not necessary.

Title: Input unit for photoelectric pulse meter
Inventor: HATTORI SHUJI
IPC: A61B5/02
Filed: 1988-03-18
Abstract: PURPOSE:To deliver a pulse waveform in accordance with a range of variations in resistance of a light receiving element which varies in accordance with a received light quantity by outputting the light quantity while an output voltage in a feed-back section for feeding back an output voltage of the light receiving element is made to be coincident with a preset criterion voltage. CONSTITUTION:A resistance of a light receiving element 2 or an output voltage Vo is determined in accordance with a received light quantity which is emitted from a light emitting element 1 and is received by the light receiving element 2 after passing through an object to be measured, and a variation in the received light quantity is detected as a variation in voltage. The output voltage Vo is delivered through a feed-back section which is in such a condition that a switch 5 is closed, to a comparator 7 which compares the same with a preset voltage Vc delivered from a set voltage output section 8. If Vo is less than Vc, the current running through the light emitting element 1 is decreased, but if it is not less than that, the current is increased. When Vo coincides with Vc, the switch 5 is opened, and simultaneously, the feed-back section 4 delivers the voltage Vc charged in a capacitor 6. With this arrangement, the brightness of the light emitting element 1 is held as it is, thereby it is possible to measure the output of the light emitting element 1 by a measuring unit body as a stable and reliable pulse wave.

IPC: A47L9/28
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To improve cleaning workability while preventing damages by the temperature rise of a motor-driven blower. SOLUTION: By the setting operation of an operation means 44, the motor- driven blower 13 is driven and dust is sucked from the suction port of a suction port body part together with air and captured through a suction air path into a dust collecting chamber. Filtered air is discharged from the motor-driven blower 13 into a motor-driven blower chamber as ejection air. The ejection air is partially discharged from the discharge port of a discharge chamber and blown through an ejection air path to a floor surface and the dust is blown up and sucked from the suction port again. When the temperature of the motor- driven blower 13 is elevated by dust clogging or the closing of the discharge port, the temperature rise of the motor-driven blower 13 is detected by a temperature sensor 38a.  A control means 110 reduces the input of the motor-driven blower 13 in the state of maintaining the size relation of the different input corresponding to the setting operation of the operation means 44. The heat damage to the motor-driven blower 13 is prevented while maintaining plural cleaning forms corresponding to cleaning conditions.
