摘要:
A temperature control system comprises a heat sink heatable upon application of electric power thereto, an AC power source for heating the heat sink, temperature detector means for detecting the temperature of the heat sink, and control means for controlling the electric power applied to the heat sink in accordance with an output signal from the detector means so that the heat sink maintains its required temperature. The control means is operable to cause application of a full power of the power source to the heat sink at the initial heating stage thereof and application of a partial power of the power source to the heat sink when the temperature thereof is in the vicinity of the required temperature.

A frame generation device has a frame generation section that generates a frame including synchronization information for achieving synchronization with a reception device from among a group including one or more reception devices each of which receives information within the frame, address information indicating an address within the frame for transmitting data, and data transmitted to the reception device included in the group. A group-basis distribution data presence/absence information generation section generates group-basis distribution data presence/absence information indicating whether or not the transmitted data is included in the frame. A synchronization information generation section generates synchronization information including the group-basis distribution data presence/absence information. The frame generation section generates the frame such that the group-basis distribution data presence/absence information is allocated prior to the address information. A central processing unit controls operation of the frame generation section, group-basis distribution data presence/absence information generation section, and synchronization information generation section.

A wiper driving apparatus comprising: a drive gear rotated by a motor; a clutch member rotating together with the drive gear only in a direction the drive gear is biased to; a pair of electric conductor plates for turning on and off an electric circuit of the motor; a pair of movable contacts rotatable relatively with the electric conductor plates in sliding contact with the electric conductor plates, respectively; and a housing rotatably supporting the clutch member with a supporting axle and having the electric conductor plates provided concentrically therewith; wherein both of the movable contacts and the clutch member are rotated integrally with one another. The clutch member is formed as a conductive member, one of the movable contacts is formed integrally on the clutch member, and the electric conductor plate, on which the movable contact slides, is disposed adjacently to the supporting axle.

In image formation control apparatus having a process unit for forming an image on a recording medium and mechanisms for assisting in the image formation, there is provided a first controller for controlling the timing of the process unit. A second controller is provided for rendering at least a portion of the process unit inoperative when an image formation is not being executed, and for thereafter rendering at least one of the assisting mechanisms inoperative while continuing to apply power to the first controller to enable image formations to be resumed.

A device for detecting a body comprises transmitter means, receiver means for receiving the signal from the transmitter means, means for setting the level of a reference signal by the reception signal from the receiver means provided when the body is in a reference condition, to correct the reference signal, which reference signal provides a reference for identifying the reception signal, and comparator means for identifying the reception signal in accordance with the reference level connected to the reference level setting means. The body detecting device effects the detection by the output of the comparator means.

摘要:
A group-basis distribution data presence/absence information generation section generates distribution data presence/absence information indicating whether or not data to be transmitted to a reception device included in a group that includes one or a plurality of reception devices is included in a frame. Further, a synchronization signal generation section generates synchronization information including the distribution data presence/absence information.
摘要:
Automatic self-aligning ball metals rotatably mounted at both end parts of a rotor shaft in an electric motor are supported by holding devices. The holding device is designed in the form of a disc having a flange portion around the outer periphery thereof. It is formed with a plurality of pawls having different intensities of resilient force which extend in the radial direction from an area located in the proximity of the flange portion. The pawls having a higher intensity of resilient force and the pawls having a lower intensity of resilient force are alternately arranged in the peripheral direction of the holding device and the inner part of each of the pawls is bent at a certain inclination angle. The pawls having a lower intensity of resilient force are adapted to come in contact with the metal ball earlier than the pawls having a higher intensity of resilient force. Each of the pawls having a higher intensity of resilient force has a width wider than the pawls having a lower intensity of resilient force. The pawls having a higher intensity of resilient force may have a thickness more than the pawls having a lower intensity of resilient force on the assumption that they have the same width. Usually, two kinds of pawls which are alternately arranged are used. Three kinds of pawls may be employed.
