Title: Color tone control method
Inventor: SHIMIZU SHIGERU
IPC: G03G15/00
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To embody a color tone control method which is capable of regulating the color tone simply by using a printing function of a printer. SOLUTION: A gray chart consisting of five pallets 61-1 to 61-5 of gray patches of three colors Y, M and C previously mixed at prescribed density ratios (five stages of the range of 30 to 50%) and gray targets G40-1 to G40-5 for comparison arranged in dots to a checkered pattern formed at a linear density coarser than the linear density of these pallets are printed and outputted. A user compares the gray patches of such arrays and the gray targets alongside thereof and selects the gray patches with which the gray tones are best reproduced. The user then inputs the selected patch information, such as their number and the coordinate values of the arrays, to the printer.  The printer calculates the color tone correction values of the respective colors Y, M and C from the mixed Y, M and C information of the selected gray patches and rewrites the table for correction in the printer, thereby regulating again the color balance of the color images.

Title: Temperature controller
Inventor: SATO TAKEO
IPC: G05D23/00
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of defective products and to improve the reliability by dropping the internal temperature of a vacuum container when the measured internal temperature of the container is higher than a set level and keeping an idle state of a temperature controller until its internal temperature reaches a specific range including the set temperature. SOLUTION: A control part 5 transmits the set temperature to a temperature controller 4 and receives the input of a monitor temperature signal from the controller 4 to compare it with the set temperature. Then the controller 5 outputs a control mode signal to turn on a heater 3 when the temperature shown by the monitor temperature signal is lower than the set temperature and then outputs a control mode signal to turn off the heater 3 when the monitor temperature is higher than the set temperature. Furthermore, the part 5 decides whether the monitor temperature is lower than the set temperature. If the former temperature is lower than the latter one and also lower than the temperature (X-A) that is decided by subtracting the numerical value A set previously from the set temperature X, the controller 4 is set in an idle state.

The shaft is connected to a driving source provided on a main frame via a coupling and the core 5 is grounded via a main frame. The charge by the rubbing of the brush roll 3 and the photosensitive material 1, therefore, flows to the ground and charges are not held. Thus, the paper dust electrified negative is cleaned by the electrostatic effect and mechanical force of the brush roll 3.

IPC: H01L31/04
Filed: 1989-11-10
Abstract: PURPOSE:To reduce power loss by adopting the constitution such that the reverse flow prevention diode of a solar battery is used in common as an optical signal sensing resistor. CONSTITUTION:When a solar battery 101 does not generate power, in order to prevent reversing of a current from a battery B1 to the solar battery 101, a reverse flow prevention diode D1 is connected. Moreover, when the solar battery 101 receives AC signal light 102, the reverse flow prevention diode D1 acts also like a resistor to detect the AC signal. The signal detected by the said reverse flow prevention diode D1 is given to an RC circuit (comprising R1, C1), from which only the AC component is separated. Furthermore, the AC signal is supplied to an amplifier A1, where the signal is amplified and outputted to a signal output terminal Sig. Thus, a conventional optical signal sensing resistor R2 having used in a conventional panel is omitted and the power loss is reduced.

Title: Suspension for driving wheel of vehicle
Inventor: KATO TAKASHI
IPC: B60G3/20
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To increase driving force by preventing idle rotation in a turning inner side rear wheel at turning time by setting suspension geometry so as to become large to the toe-in side by generating a difference not less than a specific degree between a toe angle and a toe angle at maximum bump time by the toe angle at maximum rebound time caused by turning. SOLUTION: A difference between a toe angle (a) at maximum rebound time of a rear suspension at vehicle turning time and a toe angle (b) at maximum bump time of the rear suspension at vehicle turning time is determined. Suspension geometry of the rear suspension is set so that the difference (a-b) becomes large. Particularly, the suspension geometry is set so that a value by subtracting the toe angle (b) at maximum bump time from the toe angle (a) at maximum rebound time becomes 0.5 degree or more. Thus, a wheel speed of a turning inner ring becomes a value closer to a wheel speed of a turning outer ring to restrain the occurrence of idle rotation in a turning inner side driving wheel to the possible minimum level to increase driving force.

CONSTITUTION:Solar beam is irradiated on a flat surface 12 of a single-side prism plate 5. The solar beam B in the morning and evening and at the noon besides on the vernal and autumnal equinoxes is refracted by this prism plate 5 to become B', and its angle to the optical axis D of a lens 6 is lessened. The solar beam B' is further refracted by the lens 6 to the focal direction to become B'' and led to a light introducing hole 9 via a reflex throat 7. As its length H in the optical axis direction is approx. the same as the focal distance of the lens 6, the solar beam B'' is focused to form an image at the light introducing hole 9. When the sun altitude is low, the solar beam is reflected by the inner surface of the reflex throat 7 and irradiated to the light introducing hole 9, wherein the number of reflections at the reflex throat 7 is less than the solar beam C in case not penetrating the single-side prism plate 5, and also damping of the light is lesser.
