Title: Photograph printing method
Inventor: IKEGAMI SHINPEI
IPC: G03B27/72
Filed: 1991-04-19
Abstract: PURPOSE:To obtain prints having an appropriate photographic density at high probability from a picture image photographed with a camera in which an exposure is automatically decided. CONSTITUTION:When a negative film, in which a picture image is photographed by a so-called multipoint photometry method deciding an exposure by making the photometry of different areas on a subject with plural photometry elements, is printing-treated, printing treatment by an average exposure is performed. That is, the photometry of all picture image frames of the negative film is made to determine the average photographic density of a whole picture plane at each R, G, and B (steps 112 and 114). Then the mean value of the average density of the whole picture image flames of the negative film is operated (step 118) to decide a printing exposure quantity by using the mean value (step 120). The printing treatment of all the picture image frames is conducted by using the printing exposure quantity (steps 122 and 124).

Title: Power supply protective unit
Inventor: YOSHIKAWA SHIGEO
IPC: H02M3/28
Filed: 1990-04-03
Abstract: PURPOSE:To protect a drive element by arranging a capacitor, passing only an AC component, in series with the input of the drive element in a circuit for driving the drive element. CONSTITUTION:A power supply protective unit comprises a circuit 4 for controlling a switching regulator and a drive element 3 being driven by a drive circuit 21 and driving a converter transformer 1. A capacitor 22, passing only an AC component, is arranged in series with the input of the drive element 3 in the drive circuit 21. When the switching regulator is protected, DC voltage can be cut off by the capacitor 22 even if the output from the control circuit 4 has a DC potential of constant amplitude. Since ON state is not sustained in the drive element 3, large current does not flow into the drive element 3 and thereby the drive element 3 is protected against breakdown resulting in protection of power supply circuit.

IPC: F16K17/36
Filed: 1980-06-30
Abstract: PURPOSE: To obtain a lightweight small-sized valve by allowing the switch valve which communicates to and cuts off the evaporated fuel control passage which communicates to a fuel tank and a carburetor to operate in correspondence to the negative pressure and constituting the negative pressure control apparatus for controlling the switch valve separately from the switch valve.  
     CONSTITUTION: The switch valve 10 equipped with a diaphragm piston 14 which communicates to and cuts off the evaporated fuel control passage which communicates to a fuel tank and a carburetor is constituted to operate in correspondence to the negative pressure, and the negative pressure control apparatus 20 equipped with a ball 25 and a valve means for 26 for controlling the switch valve 10 is constituted separately from the switch valve 10. For example, when a car turns sideways, the ball 25 moves freely and is separated from the top edge 262 of the valve body 26a. As a result of this, the valve body 26a is moved upward, and communication to the fourth and the fifth balls 21a and 21b is cut off. Therefore, negative pressure feeding from the intake pipe to the upper chamber R 1  of the switch valve 10 is stopped, and the negative pressure in the upper chamber R 1  is reduced by the air which flows-in through an orifice 263. Then, the piston 14 moves downward, and communication to the first and the second ports 11a and 13a is cut-off.

Abstract: PURPOSE:To obtain such a device that an origin signal does not vary in pulse width in a moving direction by forming a bridge circuit composed of two series circuits connected in parallel by using four blocks consisting of plural magneto-resistance effect elements, and providing it with a differential circuit. CONSTITUTION:When an origin position detection pattern 1a approaches from let and moves away to right, the blocks B1 B2 B3 B4 are magnetized in order and vary in resistance value respectively and the internal between two peaks that the variation curve has is twice the width of the pattern 1a. Then, the blocks B1 and B2 are connected in series and both their ends are connected to a source voltage terminal and a grounding terminal GND, so the potential of the 1st output signal from the connection part L1 between the blocks B1 and B2 is equal to the difference in resistance variation rate between the blocks B1 and B2. Further, the potential of the 2nd output signal from the connection part L3 between the blocks B3 and B4 is the same. The voltage difference between those two output signals is amplified by the differential amplifier circuit 2 and the first peak of its output signal has good symmetry and is processed by a rectangular wave modulating circuit 3, whose output is outputted to an origin signal output terminal 4.

Title: Night cover for low-temperature showcase

IPC: A47F3/04
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce freezing and dew condensation by making an infrared-ray absorptivity on a surface a outside of a compartment higher than that on the surface inside it, and also making an infrared-ray reflectance on the inside surface higher than that on the outside surface. SOLUTION: The infrared-ray reflectance is improved by making a color light and having a gloss in a base material 11. In the meantime, a high infrared-ray absorptivity layer 12 consists of the paint of a dark color and the layer 12 at the outer side of the compartment is provided with the lower infrared-ray reflectance and the higher infrared-ray absorbing rate as compared with the base material 11 at the inner side of the compartment. An infrared-ray emitted from air in the upper part of the compartment 3 is reflected by the material 11 with the comparatively high absorptivity and radiation cooling in the upper part of the compartment 3 is prevented. The temp. of cool air in the upper part of the compartment 3 is increased as much as possible and temp. difference between in-compartment temp. and the out-of-compartment temp. is reduced.  Moreover, the outside infrared-ray is absorbed in the layer 12 so that the temp. of a night cover 6 is increased and difference between the cover 6 and outside temp. is reduced so that the due condensation and freezing of the cover 6 is further prevented.
