Title: Board with tiles arranged in rows and manufacture of tile unit using the board
Inventor: KANAYAMA SHOGAKU
IPC: B28B11/00
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To keep a tile pitch by the board with tiles arranged in rows and prevent a joint pitch of the tiles from shifting by forming through holes in the board with tiles arranged in rows for covering tiles arranged in rows to such the tiles. SOLUTION: Tiles (a) are housed in each section partitioned by lateral projections 3 in an upwardly turned board 2 with tiles arranged in rows, and a downwardly turned board 4 with tiles arranged in rows on which the simillar projections 5 are formed is put from above and transferred by a conveyor. The tiles (a) are sucked by sucking elements of a sucker 7 through through holes 6 formed in the downwardly turned board 4, and transferred onto a transfer plate on which a synthetic resin raw material forming a bridge piece is applied and put in a curing device together with the downwardly turned board 4 to cure the synthetic resin raw material and mutually connect a plurality of tiles. Finally the transfer plate and the downwardly turned boards 4 with tiles arranged in raws are removed. In this way, each distance of tiles (a) is kept from the initial process to the last by the projections 5 of the boards 4.

Title: Semiconductor device and its manufacture
Inventor: ONOUCHI YUKIHIRO
IPC: H01L21/331
Filed: 1990-09-28
Abstract: PURPOSE:To effectively prevent the increase of an emitter series resistance, by constituting a step-difference in an emitter aperture part as two stages. CONSTITUTION:A thick silicon oxide film 2 is thin in the vicinity of an emitter 4. Along said thin part and the surface of the side part, a silicon nitride film 3 is formed. Hence a step-difference of two stages are formed in a large aperture part formed in a polycrystalline silicon film 6 being a base leading-out electrode. A second step-difference determined by the thick silicon oxide film 2 is much larger than the step-difference of an emitter aperture part 10 being a first step-difference. As a result, when the size of an emitter becomes very small, and the emitter aperture part 10 having the first step-difference is filled with a polycrystalline silicon film 1, the outside aperture part having the second step-difference much larger than the first step-difference is not filled up. Thereby the increase of an emitter series resistance can be effectively prevented, so that the operating speed is improved and the cutoff frequency is increased.

Abstract: PURPOSE:To make it possible to improve the conveying efficiency by cutting off a carrier and a power chain with a stopper member in a downhill, stopping the drop of the carrier by the dead load making the carrier at a waiting position, and preventing the drop by the dead load until the carrier is reconnected by a carrier restarting device. CONSTITUTION:When a carrier 7 is made in a waiting position in a downhill 3, a carrier drop preventive plate 28 is removed from a recess 5a of a power rail 5 and converted to the backward movement position by positioning a stopper member 29 in the forward movement position to the side of the rail 5 by a cylinder 27. As a result, when a carrier dog 10 geared with a chain dog 9 comes to the position of the recess 5a, the dog 10 is contacted to a planger 29a, the dog 9 interferes with the stopper member 29 as well as the running of the carrier 7 is stopped. In this case, since the dog 9 is positioned at the recess 5a, and made rotatable to the falling direction, the dog 9 is laid down and the gearing to the dog 10 is released, a power chain 8 continues its running, and the carrier 7 is stopped on the way downhill 3 and placed in waiting position.

Abstract: PURPOSE: To eliminate the troublesomeness of operations by holding a communication state by a communication holding device when the communication state is started, stopping a function by the operation of dials and function buttons and cancelling function stoppage by a function recovery device when communication is ended. CONSTITUTION: When a communication button 32 is pushed without calling signals being inputted, after the operation of dial buttons 31 is ended, whether or not tone stoppage signals from a tone detection circuit 29 are inputted is judged. The circuit 29 detects ring back tones from an exchange emitted at the time of calling a called party and sends out the tone stoppage signals to a control part 30 when the input of the ring back tones is stopped by the response of the called party. At this time, the control part 30 judges that the communication state with the called party is started, holds the communication state and judges whether or not a recovery button 33 is pushed. When the communication is ended and the recovery button 33 is pushed, the holding of the communication state and the function stoppage are cancelled.

Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To increase the baking frequency of the bread dough by simplifying the complicated pre-baking operations, reducing the frequency of the thawing works as well as the bread dough-forming works in order to save the total labor in the pre-baking treatment of ball-shaped frozen bread dough. SOLUTION: The two processes of the thawing of the frozen ball-shaped bread dough and the fermentation of the dough are continuously carried out, as the thawing and fermentation chamber is maintained at a temperature of 17-40 deg.C and a relative humidity of 50-70%. After completion of the fermentation process, the temperature in the chamber is cooled down to -20 deg.C to 15 deg.C at a cooling rate of >=0.2 deg.C/min, as the temperature difference between the dew- point temperature and the temperature on the dough surface is maintained less than 20 deg.C to retain the bread dough state. Then, the bread dough is formed or molded and subjected to the final fermentation to finish the pre-baking treatment.
