Title: Rotary compressor
Inventor: KAMITSUJI TOSHIO
IPC: F04B39/12
Filed: 1986-11-28
Abstract: PURPOSE:To prevent a noise caused by pipe-vibration from occurring, by bending once pipes which projected in the peripheral direction from the nighborhood of a compression-element-fixed-part in a sealed case, and fixing them around the motor-side end of a cylindrical part of the closed case by means of a belt. CONSTITUTION:Pipes 11 and 12, which project in the peripheral direction from a lid 4 of a closed case 2, are bent once toward the motor (8) side and then fastened for fixing to the neighborhood 3a of a motor (8)-side end of a cylindrical part 3 of the closed case 2 by means of a steel belt 13. With this contrivance, since both pipes 11 and 12 are refastened at a place at which the fundamental frequency of a compressor is small, the pipe vibration which will be transferred to the cooling system can be attenuated, thereby preventing a noise from occurring.

Title: Image forming device
Inventor: HATTA NAOYUKI
IPC: G03B27/72
Filed: 1989-10-31
Abstract: PURPOSE:To prevent an inappropriate image from being formed by arranging a reference white board at a reference position, irradiating it with light and judging that an error occurs when it is judged that the reference white board is moved from the reference position during the feedback control of the irradiating light quantity. CONSTITUTION:The reference white board M2 is attached to an original platen M1 which moves from side to side and the reference white board M2 is arranged at the reference position and irradiated with the light. Based on the reflected light from the reference white board M2, the feedback control of the irradiating light quantity is performed. Whether or not the feedback control of the irradiating light quantity is being performed is judged by a control decision means M3, and whether or not the reference white board M2 is moved from the reference position is decided by a reference white board movement decision means M4. When it is judged that the reference white board M2 of an original platen M1 is moved during the feedback control of the irradiating light quantity according to the decision by the means M3 and M4, an error decision means M5 decides that the error occurs because it is considered that the appropriate feedback control of the light quantity is impossible. Thus, the copied image is properly formed by appropriately adjusting the light quantity.

Abstract: PURPOSE:To extend a repeater reception area and to attain common use of a device by installing plural low voltage repeaters to a low voltage distribution line so as to attain multi-stage relaying. CONSTITUTION:When a repeater 1 calls a terminal equipment 3 of a reception area of a low voltage repeater 2d, a repeater 2a counts a reception time when the repeater 2a starts the reception of a signal from the repeater 1, and stores number of low voltage repeaters after the end of reception and sends the number decremented by one to a repeater 2b and does not detect a signal for a time being a multiple of the low voltage repeaters of a time required for the reception after the end of this transmission. The operation above is repeated up to a repeater 2d at which number of the low voltage repeaters is zero. The repeater 2d converts the data into data from which number of repeaters is eliminated and sends the resulting data to the terminal equipment 3. Then the repeater 2d receives a response from the terminal equipment 3 and sends the response signal with number of repeaters added thereto to the repeater 2a via the repeaters 2c, 2b and the repeater 2a sends the data to the repeater 1, then the data are sent from the repeater 1 to the terminal equipment 3.
