Title: Constant speed traveling device for car
Inventor: SATOU HITOSHI
IPC: F02D29/02
Filed: 1983-04-30
Abstract: PURPOSE:To keep a constant speed for a car when it runs on an ascending or descending road by using a speed correcting circuit which delivers a signal that is superposed on the output signal of a D/A converting circuit for signals. CONSTITUTION:A speed sensor 3 is revolved with traveling of a car, and the output of the sensor 3 is led to a speed integration circuit 7 to actuate a differentiating circuit 7a, a monostable-multivibrator 7b and an integration circuit 7c respectively. Then the output corresponding to the speed of a car is delivered to an output point (a). When the car running on an ascending road, the output signal of a transistor TR9 is integrated by a speed compensating circuit 10c. Then a signal of a high level is applied to an input terminal of positive pole of a comparator 10a. While the car speed voltage is applied to an input terminal of negative pole of a comparator 10a from the point (a). The voltage of the positive pole side input terminal of the comparator 10a is larger than that of the negative pole side input terminal. As a result, the comparator 10a is actuated to deliver a signal of a high level. This signal is added to the output voltage of a D/A converting circuit 6 to reduce the speed of the car.

Filed: 1998-03-10
Abstract: PROBLEM TO BE SOLVED: To impart an illumination structure for enabling image observation under a dark environment without damaging image quality under a bright environment to a reflection type display device. SOLUTION: This reflection type display device is composed of a panel 0, a light guide plate 20 and a light source 30. The panel 0 is provided with a transparent first substrate 1 positioned on the incident side of external light, a second substrate 2 joined to the first substrate 1 through a prescribed clearance and positioned on a reflection side, a liquid crystal layer 3 held inside the clearance of both substrates and an electrode 10 for applying a voltage to it. The light guide plate 20 is mounted on the outer side of the first substrate 1 and the light source 30 is disposed at the end part 25 of the light guide plate 20 and generates illumination light as needed. While the light guide plate 20 normally transmits the external light, makes it be incident on the first substrate 1 and emits the external light reflected from the second substrate 2, it guides the illumination light, makes it be incident on the first substrate 1 and emits the illumination light reflected from the second substrate 2 as needed. A polarizing plate 70 and a 1/4 wavelength plate 80 are piled up and mounted on the light guide plate 20 and the external light or the illumination light unnecessarily reflected from the first substrate 1 of the panel 0 is interrupted.

Filed: 1988-03-29
Abstract: PURPOSE:To enable printing paper to be surely fed preventing a paper feed roller from wearing by racing a slip roller so as to prevent transmission of drive torque from a printer to the paper feed roller when friction torque not less than a predetermined value acts on the paper feed roller. CONSTITUTION:A paper feeder, when it is mounted to a printer, transmits drive torque to a paper feed roller 3 of an angular shaft 1, connecting a gear 2d, from the printer through a rotation transmitting system 2. A slip clutch 4 races when transmitted torque to the roller 3 increases to a value not less than the specified, that is, when printing paper is present in a hopper, the clutch 4 generates no racing for the printing paper in its feed torque, rotating with a gear 2a transmitting the torque to paper feed rollers 3a, 3b. However, the hopper provides no printing paper with the rollers 3a, 3b coming into direct contact with a pressure plate 12, when friction torque acts on the rollers 3a, 3b, the clutch races transmitting no torque to the rollers 3a, 3b from the printer. Accordingly, a surface is prevented from wearing because the rollers 3a, 3b are not rotated.

Abstract: PURPOSE:To eliminate uneven delivery by providing a pair of delivery rollers in the upstream part in a carrying direction from carrying rollers, and detectiang sagging at a clearance part between the carrying roller and the delivery rollers for collecting the feed motion of the pair of delivery rollers. CONSTITUTION:At the same time when a facsimile equipment 11 starts printing, a platen roller 4 and a pair of delivery rollers 12 start rotating to carry a sheet 2 to be recorded. At this time, because the peripheral speed of the pair of delivery rollers 12 is little higher than that of the platen roller 4, the sagging 2A of a sheet A to be recorded is generated between the rollers 4, 12, and the sagging 2A enters the clearance 13 to move downwards with the passage of time. When the sagging 2A lowers to a position where the sagging is detected by a recorded sheet sensor 15, the rotation of the pair of delivery rollers 12 is stopped for a certain time based on the output from the recorded sheet sensor 15 through a control part. Under this condition, the sheet 2 to be recorded in the clearance 13 is carried, and after a certain time passes, the pair of delivery rollers 12 are rotated again.
