Abstract: PURPOSE: To prevent the infiltration of liquid, such as water drops, while well maintaining the flow of air for cooling by joining one side parts of louver members existing right under openings and having recessed parts for reserving liquid in the other side parts to grille members. CONSTITUTION: This casing for electronic apparatus has a vent port opened to face upward. The plural louver members 36 formed at the grille members 34 in correspondence to the respective apertures 35 of the grille members 34 are joined in their one-side parts to the grille members 34. The other-side parts are arranged apart from the grille members 34 so as to exist right under the respective apertures 35. Further, the other-side parts parted from the grille members 34 are provided with the recessed parts 37 for reserving liquid. As a result, the flow of the air through the respective apertures 35 is not blocked and the water drops infiltrating from the upper side to the respective apertures 35 are reserved in the recessed parts 37 for reserving liquid, by which the passage of the water drops through the apertures 35 is prohibited.

Title: Image forming device
Inventor: AKIYAMA YASUHISA
IPC: G03G21/00
Filed: 1983-12-20
Abstract: PURPOSE:To perform automatic means density setting easily by providing a manual density setting means which allows density setting in >=3 stages in addition to an automatic density setting means, and switching the density setting means with three signals. CONSTITUTION:When a light key 83 or dark key 84 is depressed in automatic exposure mode, the center P31 of a display pattern turns on and every time the light key 83 is further depressed, selections are changed by one stage in a thinner copy density direction. When the light key 83 is depressed continuously for longer than a specific time, the copy density decreases stepwise at specific intervals of time. The depression of the dark key 84 is the same. Display patterns P28-P34 are turned on selectively according to said key operation to display selected copy density (exposure) visually. Consequently, the manual density setting is performed in many stages more than three and the number of stages is increased or decreased when necessary.

Abstract: PURPOSE:To speed up the phase difference calculation with a simple circuit by obtaining the phase error between the in-phase component and the orthogonal component by using a memory calculating and storing the phase difference data between a carrier wave and a reference wave. CONSTITUTION:A reception signal is demodulated by controlling the phase of a reproduction carrier wave according to the phase error between an in-phase components I and an orthogonal component Q which is synthesized and detected by a carrier wave reproduced from a PSK reception signal to be demodulated. In this case, the phase difference data phi between the carrier wave of a reception signal and the reference carrier wave in detecting the phase error is stored in a memory 35. Latching data I and Q are latched by latch circuits 27 and 28 and are inputted to the address of a corresponding memory 35. By accessing the memory 35, a phase error signal phi is obtained. Thus, the compact, high- speed processing circuit with less power consumption can be provided by using one memory instead of the logic IC.

Abstract: PROBLEM TO BE SOLVED: To move a rack member and turn a sickle lock in a locked state in automatic mode by energizing a solenoid or an electromagnet mounted on a door frame when a sliding door is closed. SOLUTION: When a solenoid 30 is energized, an operation lever 35 is contracted so that its magnetic member 36 may approach a window 37 of a receiving metal fitting 33 and a magnetized member 46 of a rotary engagement body 40, thereby turning in the counterclockwise direction against a spring 42. During the turning, the magnetized member 46 of a forward arm is separated from a window 14 of a front 31 while a sickle lock member 60 is turned in the clockwise direction. On one hand, since the backward arm 45 of the rotary engagement body 40 is turned in the same direction with the sickle lock member 60, the rotary lock member 50 is turned in the clockwise direction against the spring 51. As a result, a rack member 20 is released from the rotary engagement member 50 so that it may drop by a spring force of a rack spring 25.  Then, a pinion member 5 and a cylinder 4 are turned in the clockwise direction while a sickle piece 6 of a sickle lock advances into an opening 34 of a catch metal fitting 33 where a short lever 64 of the sickle lock member 60 is opposed in an engageable state with the surface of a stopper 11 of a small projected piece 12.
