Abstract: PURPOSE:To maintain minimum necessary opening area for wiring at all times by providing a cut-out hole in the side end portion of a duct cover for a wiring duct, a lid capable of opening and closing longitudinally of the cutout hole and an articulated mechanism for giving multiple stage articulated operation to the lid in opening and closing between the lid and duct cover. CONSTITUTION:A lid 61 opens and closes a cutout hole 62 in a duct cover 6. When the lid 61 is pushed longitudinally of the duct cover 6, an engaging projection 61a on the tip of a tongue 61b of the lid 61 engages an engaging projection 64 of the duct cover 6. When the lid 61 is further pushed, the tongue 61b forming an articulated mechanism 67 is elastically deformed parpendicularly to the inner surface of the duct cover 6 to operate articulately engaging projection 61c. Thus, the opening part of the cutout hole 62 ensures a space necessary for passing a telephone wire therethrough and the most of the opening part is closed by the lid 61. Then, the tongue 61b engages a recess 64a on the engaging projection 64 to be restricted from movement.

Abstract: PURPOSE: To perform automatic aperture controlling with compensated response delay by adjusting the counting of the pulses generated by way of an aperture control member by making use of the pulses which the control member generates in an idle running region.  
     CONSTITUTION: When an aperture control member 4 moves, a gear 3 turns cooperatively, and pulses are generated from a pulse generator PC. A predetermined idle running region has been set in the drive member 6 cooperating with this member 4, and until the driving of the idle running region is completed, the member 6 does not contactually touch a drive pin and stopping is not accomplished. When the added value of a predetermined number of adjusting pulse number out of the pulses generated by the generator PC at the idle running and the count value of the pulses generated by the generator PC after the stopping in succession to the counting of said adjusting pulse number coincides with the operated value, an aperature control magnet AP-MG is de-energized to stop the member 4. Hence, the response delay via the magnet AP-MG is beforehand corrected by the adjusting pulses and the automatic aperture adjustment with corrected response delay is accomplished.

Abstract: PURPOSE:To maintain the brightness of a display surface and to increase contrast in a storage type liquid crystal display device by superposing two liquid crystal layers consisting essentially of nematic liquid crystals exhibiting hysteresis characteristics and cholesteric liquid crystals on top and bottom. CONSTITUTION:The liquid crystals 18, 19 obtained by adding cholesteric liquid crystals to mixed liquid crystals of an (n) type nematic liquid crystal and a (p) type nematic liquid crystal are used as the liquid crystals having a storage effect utilizing hysteresis characteristics. Such cells are superposed on top and bottom. The cells have transparent substrates 15, 16, 17 and transparent electrodes 11, 12 and 13, 14 which face to each other are disposed on the transparent substrates. While no voltage is applied, the liquid crystals 18, 19 are transparent and the light transmittances thereof are 80% and the brightness of conventional devices is maintained. When voltage is applied, they assume a light scattering state and the light transmittances drop to 25%. The contrast ratio is increased to 80%/25%, that is, 3.2, which is about 2 times higher than that in the prior art.

A refrigerant in a refrigerant storage device 20 is increased in a low boiling point component, the composition of a refrigerant flowing through a main circuit is brought into a state to have quantities of high boiling point components, and high-efficient control of capacity can be effected. Meanwhile, when the frequency of a compressor is increased and exceeds a set value, the continuing time is integrated by means of a timer 30, and an integration result is compared with a set time stored in the microcomputer 26. When the result is higher than the set time, the solenoid on-off valve 21 is opened, and a refrigerant flows as shown by the arrow of a solid line. A refrigerant in a refrigerant storage device 20 also flows as in a main circuit, the content of the refrigerant is not different from the content of the main circuit, and high capacity can be generated in a state in which a high boiling point component is mixed with a low boiling point component. Further, cooling operation is also effected in a similar manner described above.

Abstract: PURPOSE:To elevate the temperature of water introduced into the water heater by utilizing friction by a method wherein the water fed into the water heater is transferred under pressure toward an outlet through small gaps while the water is agitated by rotary plates. CONSTITUTION:A rotatable shaft 3 is mounted horizontally in a central core section of a laterally elongated drum and the rotary plates 4 and partition plates 5 are arranged alternatively within the drum 2 in the direction normal to the longitudinal direction of the drum. The central core section of each of the rotary plates 4 is fixed to the shaft 3 and the outer periphery 4A of eac of the plates 4A provides the small gap 4B with respect to the inner wall of the drum 2. On the other hand, the outer periphery 5A of each of the plates 5 is fixed to the inner wall of the drum and a small gap 5c is formed between a circular hole 5b of each of the plates 5 and the shaft 3. Further, an outlet port 2A and a hot water outlet port 2B are formed in the left side wall and the right side wall of the drum 2, respectively. As a consequence, the water fed into the water heater is transferred under pressure toward the outer outlet port through the small gaps 4B and 5C while it is agitated by the rotary plate. In this case, the water is heated due to its frictional contact with the rotary plates 4 so that it is possible to obtain hot water without the necessity of using a fuel.

CONSTITUTION:A bar roof 4 for supporting wing doors 5, 5 is formed so that its width may be increased gradually toward front side from rear side. Therefore, the hinges 11f, 11f on front side are formed so that they may be father from the center line Lb in the cross direction of an automobile body than the hinges 11r, 11r on rear side. Namely, the hinge lines l1 on the right and left for connecting the hinges in a cross direction are inclined so that the front side may extend a little toward the outside of the automobile body to the center line Lb1 from the viewpoint of plane. As a result, the wing doors 5, 5 are inclined forward with its rear side raised more highly than its front side when a door is opened. Consequently, when the doors 5, 5 are opened on a rainy day, the raindrops on a door surface drop toward the front side of the door through which no occupants pass in getting on and off an automobile 1, thus improving the convenience in getting on and of the automobile. The doors 5, 5 rotate around the hinge lines l1, l1 so as to make no interference with any front sight.

Abstract: PURPOSE:To enable high grade recording by stabilizing a detent mechanism and accurately holding a recording position by a simple structure, by mounting a detection means for detecting that recording operation is not performed for a certain definite time and the stabilizing means of the detent mechanism driven by the detection means. CONSTITUTION:In a typewriter, recording is performed by key input and key operation is interrupted when a platen knob 15 is rotated by manual operation to move recording paper to a recording position. Therefore, no recording operation is performed during a time when the platen knob 15 is rotated and a recording interrupting state is generated for some sec. If an interrupting time is set n-sec, when the elapse of n-sec or more is judged, it is judged that the platen knob 15 is operated manually and a control part 18 excites the stop phase of a stepping motor 5 for a definite time through a driver 20. A detent gear 9 slightly revolves and the imperfect meshing state between a pawl 10a and the detent gear 9 is eliminated to be brought to a perfect engaging state and the positional shift of a detent mechanism is corrected to enable the accurate setting of the recording position.
