Filed: 1991-08-23
Abstract: PURPOSE:To speed up color recognition processing and to reduce the cost by using a grating which is a saw-tooth shaped prism as a means for resolving the colors of an original image. CONSTITUTION:Reflected light from an image visual field range 2a on the surface of the original 2 corresponding to one picture element line of an image recognizing element 10 is converged by an image forming lens 8 and made incident on the saw-tooth shaped opening part 62 of the grating 61. The light made incident on the opening part 62 is diffracted at a different angle corresponding to the wavelength and the R, G, and B light beams are made incident on picture element lines 23, 22, and 21 of a CCD 10 respectively. In this case, noise light 63 which is reflected by the surface of the original 2 outside the image visual field range does not pass through the opening part 62 of the grating 61, but travels straight outside, so the noise light is made incident on none of the respective picture element lines 21, 22, and 23. Namely, the reflected light is resolved by the opening part 62 of the grating 61 into three colors and made incident on the CCD 10, so the need for a buffer memory is eliminated.

Filed: 1990-09-07
Abstract: PURPOSE:To reduce the processing quantity in a split state by putting dynamically the page of the record moving in the split stat into a new page of a prime area. CONSTITUTION:The number of records having the has value to be stored in a page 3 of a prime area 2 is increased and therefore a fixed area secured in the page 3 is unable to store all records.

Title: Signal generating circuit
Inventor: MATSUURA YOSHIAKI
IPC: H03B5/32
Filed: 1985-10-25
Abstract: PURPOSE:To improve the signal transmission efficiency and to save the power consumption by applying a couple of signals whose phase differs by 180 deg. to a BBD element as a charge transfer control signal of the BBD element and obtaining an output signal of the desired frequency from the BBD element. CONSTITUTION:When a couple of signals obtained from an input 3a and an output 3b of a crystal oscillation circuit 2 whose phase differs by 180 deg. is impressed to a gate of a transistor (TR) being a component of the BBD element 3 as a charge transfer control signal, the BBD element applies the charge transfer control according to the period of an output signal of the crystal oscillation circuit 2. Since a signal feedback means is connected to the BBD element to inverts the level of the output signal and to feed back the result to the input, Demoting the number of TRs constituting the BBD element 3 as (n), then the level of the output signal of the BBD element is changed by a period being n-time of the output signal So of the crystal oscillation circuit. That is, the signal being the 1/n frequency division of the output signal So of the crystal oscillation circuit is obtained from the output of the BBD element. Thus, the number of elements of the circuit is less and the power consumption is decreased.

Title: Freezer device
Inventor: KAJIYAMA KOJI
IPC: H02P27/06
Filed: 1989-09-14
Abstract: PURPOSE:To make a fast reacting to a predetermined set pressure and further improve dynamic characteristic such as a reduction of a consumption power and a follow-up characteristic in respect to a variation of a cooling load by a method wherein a fuzzy estimation is carried out in response to a difference between a sensed pressure of refrigerant at a low pressure side and a set pressure and a coefficient of differentiation of the sensed pressure. CONSTITUTION:A pressure comparator 10 stores a comparator for comparing a pressure sensing signal from a low pressure sensing part 7 with a reference value set in response to a set pressure and generates a signal corresponding to a difference between the reference value and the pressure sensing signal. Similarly, a differential coefficient calculation part 11 receives a pressure sensing signal from a pressure sensing part 7, calculates a differential coefficient of a refrigerant pressure and generates a signal corresponding to a result of calculation. A fuzzy control part 12 may perform a fuzzy estimation and output a positive value in response to a signal from each of the pressure comparing part 10 and the differentiating coefficient calculation part 11. A frequency control part 13 may control an inverter 5 in response to a positive value from the fuzzy control part 11 and control its output frequency. With such an arrangement, it is possible to reach a set pressure immediately, to reduce a consumption power and thus to provide a freezer device having a better dynamic characteristic against a load variation.
