Title: Balancing device for enclosed type compressor
Inventor: MITSUNAGA TOSHIHIKO
IPC: F04B35/00
Filed: 1987-02-03
Abstract: PURPOSE:To enable a cup muffler to be larger while prevent increase in oil discharge quantity by forming the captioned device in such a way that the center of a rotor is displaced on the opposite side to the eccentric part with respect to the axis of a rotary shaft. CONSTITUTION:The center of a rotor 8 is displaced on the opposite side to the eccentric part 15 of a rotary shaft 4 with respect to the axis of the rotary shaft 4, so as to be balanced with the unbalanced force of a rotary compression element 5 by means of the rotor 8. Thereby, a balance weight which was conventionally installed on a lower end ring 13 is eliminated. Accordingly, the space 22 on the lower part of the motor driven element 3 in the rotor 8 is made larger by the amount of the balance weight, enabling the installation of a large cup muffler 21 on an upper frame body 18, while preventing a refrigerant and oil from being discharged together since the refrigerant and oil which flow into this space are not stirred by the balance weight.

Title: Automotive air cleaner
Inventor: IMAI HIDETOSHI
IPC: B60H3/06
Filed: 1991-02-18
Abstract: PURPOSE:To prevent overdischarge of a battery by providing a voltage detector, a human body detecting sensor, and a main power source which is switched on and off in response to the signals of said detector and sensor in an automotive air cleaner to actuate the air cleaner only when men are present on a car and to enable complete cleaning of the interior of car even after men have left the car by providing a delay circuit in the human body detecting sensor. CONSTITUTION:When men get into an automobile and actuate an engine, a voltage detector detects voltage drop of a battery 1 and delivers a signal to turn on a main power source switch thereby allowing an air cleaner to operate and when men leave the automobile, a human body detecting sensor 11 ceases to detect far-infrared radiation emitted from human bodies and then a microprocessor 9 delivers signals to turn off the main power source switch, whereby the action of the air cleaner finishes. Since the air cleaner can be actuated only when men are present on the automobile, even if men are apart from the automobile for a long time, without turning off the switch of the air cleaner, overdischarge of battery can be prevented.

Title: Direct-current water bottom power cable line
Inventor: HATA RYOSUKE
IPC: H01B7/18
Filed: 1993-01-18
Abstract: PURPOSE:To obtain the same effect without using a return-circuit cable as that when it is used by constituting the armoring wire of a direct-current water bottom powder cable of a copper wire or a copper alloy wire, and using it for a grounding side return current circuit. CONSTITUTION:The whole area of the cross-section of the armoring wire 2 of a direct-current underwater power cable is equal to or far larger than the cross-sectional area of a cable conductor 1 through which an internal transmission current flows. Therefore, if it is made up of a copper wire or a copper alloy wire, it can be an external conductor having smaller direct-current resistance than that of the internal cable conductor 1. Accordingly, when the armoring wire 2 of copper or copper alloy are used for a return circuit, the armoring wire having a large conductor size, a high dielectric constant and a low resistance can be a return current circuit since the potential is almost the earth potential and the fundamental functions can be effected without insulation. Therefore, for a single-pole operation system, the cable conductor 1 is used for a direct-current transmission current and the armoring wire 2 is used for a return current circuit by using one line of a direct-current underwater powder cable.

Filed: 1977-03-04
Abstract: In order to simplify the charging and accounting procedures in a telephone network and, at the same time, to carry these out in a more reliable manner, the system exhibits a multiplicity of switching devices (11, 12, 18; 21, 22, 28; 31, 32, 38) with keyboards and display devices. These are connected group by group to control devices (10, 20, 30) for the user which respond to commands keyed in in order to obtain data from peripheral storage devices and to record details of the telephone connections on magnetic tape. Each control and peripheral device exhibits microprocessors for controlling the individual functions and carrying out tests which determine the operating states of the devices and generate relevant display signals. All these devices are connected to a monitor (6) for recording these display signals. Each device can exhibit a monitoring clock generator with a counter. The latter is regularly incremented and periodically set to zero, responding to a software command. Thus, when a central processing device enters a software loop, the counter exceeds a threshold value and generates a signal indicating the presence of such a loop. The same timing generator can also reset the central processing device into a starting position and delete all data recorded as consequence of a program execution up to this time. Finally, there can be a diagnostics device so that a technician can carry out routine checks of the individual devices. <IMAGE>
