Filed: 1988-08-08
Abstract: PURPOSE:To improve service availability by performing an arithmetic process of whether another elevator is in a position capable of arriving at a generated hall call floor during a count of specified time in the case where door-open time prolonging operation has be done. CONSTITUTION:When door-open prolonging operation takes places, it is inputted into an open-prolonging operation detector, and other elevator position detection and hall call floor detection are carried out, calculating arrival predictive time (t) of another elevator with a predictive operational circuit. A comparison between specified time T and the arrival predictive time (t) takes place, and when the arrival predictive time (t) of the other elevator is shorter than the specified time T, a command for separating an open-prolonging cage 1 from control operation at once is given. Accordingly, a hall call 3 is allotted to a cage 2 so that it comes to the control operation that is less in waiting time. When t>T is the case, the command separating it from the control operation after being counted as long as the specified time. In brief, in this case, such a possibility that a close button might be pushed is high, so the cage 1 is made so as not to be separated from the control operation within the specified time.

Title: Vessel for developer
Inventor: TAKAGAKI HIROMITSU
IPC: G03G15/08
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent an externally packing vessel or workers from being contaminated by a scattered developer by discharging the air within an internally packing vessel without passing through the developer, when the internally packing vessel is to be taken out of the externally packing vessel, by means of a cap installed in a developer discharging port of the internally packing vessel. SOLUTION: A plug-opening side of a cap 4, which can be attached/detached from either plug-closing side or plug-opening side, is attached to a developer discharging port 1a of an externally packing vessel 1. By pushing up a claw part 5a of a developer discharging port opening/closing member 5 so as to abut on an installing frame 3, a gap is formed between the developer discharging port opening/closing member 5 and an air permeable sheet 6, so that an air intake passage as shown by an arrow- mark (a), which leads from a developer discharging port 2a to an opening on the plug-closing side of the cap 4 of the internally packing vessel via the air permeable sheet 6, is formed.  Accordingly, by removing the cap 4, the air within the internally packing vessel can be discharged without passing the developer, and the internally packing vessel can be taken out of the externally packing vessel 1 together with the cap 4. Thus, scatter of the developer, which may cause contamination of the externally packing vessel 1, can be prevented.

Filed: 1989-07-31
Abstract: PURPOSE:To make a substrate potential approach a constant value, stabilize a parasitic capacitance, and effectively absorb high frequency current induced in a substrate with a surface electrode, by a method wherein the resistance value per unit area of electrode is reduced, by dividing the connection part of the semiconductor substrate and the surface electrode into small sections. CONSTITUTION:By equally dividing a region covered with a surface electrode 2 into, e.g. four sections, the peripheral length of a second conducting region 4 of low resistivity is approximately doubled as compared with the conventional example, and the resistance value between a semiconductor substrate 1 and a surface electrode 2 is made approximately one half. The surface electrode part is divided in this manner, and the connection part constituted of a first conducting region 3 and the second conducting region 4 is divided into a plurality of sections, thereby reducing the resistance value between the surface electrodes 2. For example, when the resistance value R1 of the conventional electric connection part is R1=r/{2(W+L)}, the resistance value R2 in this method becomes R2=(r/4X)/(W.L/X<2>). Hence the resistance value is reduced without increasing the area of the surface electrode.
