Abstract: PURPOSE:To eliminate wasteful consumption of thermal energy while saving later reheating in order to shorten a manufacturing time by effectively utilizing the heat held by a cathode-ray tube coming out of an exhaust furnace after an exhaustion process and the sealing process of an exhauste pipe. CONSTITUTION:Each part of a cathode-ray tube in a state of high temperature when coming out of an exhaust furnace 12 reaches each prescribed temperature T15, T18 and T21 respectively by radiation cooling before moving to each device 15, 18 and 21. Then the carrier speed of an overhead conveyer 14 and the positions of each device 15, 18 and 21 are set up while leaving possibility of becoming unable only this much to satisfy the temperature conditions in each process due to the fluctuation of a surrounding temperature. Therefore, in order to surely maintain the temperature T18 when performing getter flushing, this system detects the surface temperature of each cathode-ray tube by means of a temperature sensor 17 to find the mean value of each detected temperature in the fixed period by means of a computor basing on said detected temperatures. Said means value is compared with the preset value in order to regulate the carrier speed of an overhead conveyer 14. In this way, there is no need of reheating in the manufacturing process of the cathode-ray tube after performing exhaustion and the sealing an exhaust pipe thus able to eliminate waste consumption of thermal energy.

Title: Magnetic recorder and reproducer
Inventor: SONODA MASAKAZU
IPC: G11B15/18
Filed: 1981-09-10
Abstract: PURPOSE:To always keep a tape tension constant, by decreasing a torque of one of two reel motors and increasing the other torque, in performing vari-speed reproduction through intermittent feeding of a tape with a capstan. CONSTITUTION:When a transistor 16 turns on at the first intermittent feeding, a specific voltage is applied and the torque of a motor 1m is increased. Thus, a tape is strongly pulled and the slack of the tape tension between a capstan and a reel can be prevented. Similarly, when a transistor 25 is turned on at the beginning of the intermittent feeding, a voltage dividing point reaches the ground potential and the torque of a motor 2m is decreased. Thus, the tape tension between the capstan and the reel can be mitigated and damages to the tape due to slip and vibration can be prevented.

Title: Semiconductor device
Inventor: KAWAMURA NOBUO
IPC: H01L29/737
Filed: 1987-06-08
Abstract: PURPOSE:To obtain a bipolar transistor which can operated at a low temperature by reducing a first conductivity type impurity concentration in an emitter region smaller than a second conductivity type impurity concentration in a base region. CONSTITUTION:An impurity concentration in a base region is sufficiently increased as compared with an emitter region to cause a band gap narrowing in the base region, thereby obtaining an effective hetero junction effect having effectively wider forbidden band width of the emitter region than that of the base region without using a compositional hetero junction. A competitive relation between the improving effect of an emitter injection efficiency based on the effective hetero junction effect and the decrease in the emitter injection efficiency due to the reverse of the impurity concentration occurs, but the former improving effect of the former becomes dominant at a low temperature.

Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To allow the defects not to cause significant decrease in the display quality even when defects such as pinholes, irregularity and scratches are present on the reflection face. SOLUTION: This reflection plate is constituted so that a metal thin film 2 for a mirror-face reflection plate, which is supported by a transparent base body 1 having a smooth surface, is coated with a cohesive layer 3 containing transparent particles preferably having 2.5 to 40 μm average particle size and having light-diffusing property. By this method, the cohesive layer 3 applied on the metal thin film 2 gives the light-diffusing property of the whole reflection plate, and thereby, the metal thin film 2 can be formed as a mirror face in which pinholes are hardly produced. Even when defects are present on the reflection face, abnormal reflection is reduced by the diffusing effect of the cohesive layer 3 on the reflected light and abnormal reflection by the defects becomes hardly conspicuous.
