IPC: H01L23/40
Filed: 1987-05-26
Abstract: PURPOSE:To increase the package density of electronic components, by providing the exposed parts of metallic base layers on the laminated bodies, wherein an insulating plate, on which a wiring layer is provided, and the metallic base layers are laminated, and by attaching the electronic components, which produce heat, closely to the exposed parts. CONSTITUTION:Exposed parts 6 of metallic base layers are provided on a multilayered printed wiring board 5 having the metallic base layers, in which an insulating plate having a wiring layer and the metallic base layers are laminated. Electronic parts 2, which yield heat, are attached to the exposed parts 6 tightly. The exposed parts 6 of said metallic base layers 91 and 92 are formed on both surfaces (or on one surface) on the multilayered printed board 5 having the metallic base layers by cutting and the like. The electronic components 2 are tightly attached to the exposed parts 6. Therefore, a heat radiater, which occupies a space, is not required. Heat can be directly radiated to the metallic base layers. Therefore, the packaging density of the electronic components is increased. The components can be mounted on both surfaces by the adoption of the multilayered printed wiring board having the metallic base layers.

Title: Disposal method by burying object permanently
Inventor: SAKAI GORO
IPC: G21F9/36
Filed: 1994-05-18
Abstract: PURPOSE:To secure a permanent safety in burying low-level radioactive wastes in the ground by filling an interspace with cementitious mortar blended with velan gum and dispersant in a specific ratio. CONSTITUTION:An interspace between objects buried in the ground is filled with cementitious mortar, which is solidified. With the unit water volume of 200 to 250kg/m<3> and with a low cement content (the ratio of water to cement: 70 to 400%), the mortar is prepared from impalpable powder (not including cement) of 50 to 800kg/m<3> whose average grain diameter is 10mum or less, fine aggregates of 800 to 1200kg/m<3>, velan gum of 20g/<3> to 1.3kg/m<3>, dispersant of 0 to 40kg/m<3> and inflator of 0 to 40kg/m<3>. By injecting the mortar blended with velan gum, every interspace is filled solidly and bleeding is prevented. Moreover, the small cement content dissipates fears of cracks due to the change of temperature. Therefore, a permanent filling condition free from any interspaces can be maintained and environmental pollution due to radioactive wastes can be prevented.

Title: Hand-free telephone set
Inventor: SHIRAKI KOICHI
IPC: H04B3/20
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To efficiently save power consumption and to prevent an unnatural impression from imposing a remote end talker by providing an output of a voice detection flag based on comparison between a voice detection threshold level and a level of a residual signal so as to provide detection information of a near end voice with a small error. SOLUTION: A voice detection threshold level TH(k) changes with a change in a value resulting from subtracting an echo cancellation amount D(k) from a reception signal level Lr(k). Even when the value resulting from subtracting the echo cancellation amount D(k) from the reception signal level Lr(k) is high, a residual signal level Lu(k) does not exceed a voice detection threshold level TH(k) and a voice detection flag FLG remains zero. That is, near end voice detection is made not from a level Lw(k) of an attenuated transmission signal being an output of an attenuator 10 but from the level Lu(k) of the residual signal being an input to the attenuator 10. Thus, it is avoided that a change in the level Lw(k) of the attenuated transmission signal due to the operation of the attenuator 10 is mis-detected to be a near end voice.

Title: Rotary type compressor
Inventor: KOYAMA TAKASHI
IPC: F04B39/00
Filed: 1986-06-02
Abstract: PURPOSE:To reduce noise by employing a center pin welded and fixed to an end of a closed case for supporting and fixing the closed case at a position approximately on a same axis with that of a motor-operated compression element and making the center pin of a tapered shape thinner toward the end. CONSTITUTION:A center pin 10 of a tapered shape becoming thinner toward its end is welded and fixed to a closed case 2 for directly holding a motor- operated compression element in a fixed condition in a position approximately same with the axis of the closed case 2.

Title: Tracking system for optical recording/reproducing system
Inventor: TSUJIOKA TSUYOSHI
IPC: G11B7/09
Filed: 1989-05-19
Abstract: PURPOSE:To detect a tracking error by arranging the positions of plural beam spots formed at reproduction of signals in parallel to a straight line L where the scan ends are arranged and performing the comparison between the tracking error and the levels of plural reproduction signals which are obtained simultaneously in a scanning process of the parts near the scan ends. CONSTITUTION:Many signal tracks 41 are divided into the track groups 4 consisting of tracks of the same number as the laser beams. If a tracking error exceeding a track pitch occurs at reproduction of a signal and one or more beam spots 51 included in the same beam spot group 5 get completely out of a prescribed track 41, the signal reproduced from the area where a certain spot 51 are produced has a level lower than those of the reproduction signals produced from the areas of other spots 51. Therefore the difference of levels are detected among the signals of the areas where three spots 51, for example, are produced are detected based on the reproduction signals obtained from two spot areas of both ends. Thus, a tracking error signal is produced and therefore a tracking error is corrected.

Abstract: PURPOSE:To prevent a read data or a print data from being disturbed even when backward scanning is applied reversely in error by adopting the constitution that the data control in response to the moving position of the device main body is always implemented. CONSTITUTION:When the device main body is detected to be moving in a prescribed direction by a movement detection means 24 provided with a memory 114 for picture data storage to detect the movement of the device main body, the write or readout address of a picture data in the memory 114 is incremented sequentially in response to its moving distance by an address counter 111 and when it is detected by the movement detection means 24 that the device main body is reversed against the prescribed direction, the write or readout address to the memory 114 is decremented in response to its moving distance thereby implementing the data control corresponding to the moving position of the device main body at all times. Thus, even if the device main body is scanned backward in error, no data disturbance is caused and accurate data processing is progressed.
