Title: Production of base for photographic paper and apparatus therefor
Inventor: OZAKI KAZUO
IPC: G03C1/79
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to drastically lessen the generation of craters and to substantially prevent the increase of a running cost even if a base for photographic paper is produced by increasing the traveling speed of a base material. SOLUTION: A resin film 11 in a molten state discharged from an extrusion die 12 is applied on the surface of the traveling base material 22 and thereafter, a first nipping operation is carried out between a cooling roller 14 and a first nip roller 16, by which a laminate 26 consisting of the base material 22 and the resin film 11 is formed. Next, the nipping operation is again carried out between renipping rollers 20 and the cooling roller 14 while the resin film 11 of the laminate 26 is still in the molten state.  As a result, even if the craters are generated on the resin film surface by the first nipping operation for press bonding the resin film 11 to the base material surface, the resin film surface is smoothed and flattened by the roller effect of the renipping rollers 20 by the renipping operation and, therefore, the craters generated by the first nipping operation may be drastically decreased.

Title: Semiconductor disk device
Inventor: SEKI KAZUHISA
IPC: G06F12/16
Filed: 1985-07-17
Abstract: PURPOSE:To improve both the maintanability and the reliability of a semiconductor disk device by dividing logically a semiconductor storage device into plural logic drives, saving the contents of the logic driven that received an off-line instruction to a nonvolatile storage means and then attaining the free diagnosis with an off-line to said logic drive. CONSTITUTION:A logic division setting circuit 2 is provided for division of a memory 8 into plural logic drives. An on-line/off-line indicating part 3 gives the on-line or off-line instruction to each logic drive divided by the circuit 2. When a maintenance operator informs an off-line operation to a prescribed logic drive, a MPU 1 designates an off-line operation with said logic drive via the part 3. Here a memory control circuit 7 saves data stored in the prescribed logic drive which receives an off-line instruction through a transfer circuit 9 to a prescribed area of a magnetic disk device 11. In such a way, an error of the prescribed logic drive can be diagnosed with high analyzing capacity by writing various diagnosis data in addition to the conventional diagnosis program.

Abstract: PURPOSE:To easily manufacture a heat transfer tube having a notched fin of excellent heat transfer efficiency, by wrapping a notchless, slender and band- shaped fin material around a heat transfer tube and fixing it to the tube, and forming notches by moving a cutter relatively in the axial direction of the tube. CONSTITUTION:A heat transfer tube 4, supported freely rotatably by a motor 2 and a speed reducer 3 placed on a table 1, is rotated in the direction of an arrow mark (a) and is moved, at the same time, in the direction of an arrow mark (b) while adding a tensile force, by a tension roller 6, while winding a notchless and long sized fin material 5 made of Al. Thus the material 5 is spirally and tightly wrapped around the tube 4 to be formed into a fin 5a, and the front and tail ends of the material are fixed mechanically. Next, notches 9, 9a,- are formed by cutting the fin 5a with a discoidal cutter 8, driven by 24 sets of motors rotating alternately in a reverse direction, while the tube 4 is moved. As a result, because the fin 5 is pushed by the cutter 8 to be slightly bent in the axial direction of the tube 4, the fin 5a is slightly bent zigzag by making notches 9, 9a,- as turnup boundaries, and then, a heat transfer tube having a desired notched-fin is obtained.

Title: Safety device for parking brake for vehicle
Inventor: TOTSUKA TAKASHI
IPC: B60T7/12
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a safety device for a parking brake for a vehicle capable of preventing inappropriate automatic stop due to swing of a vehicle by loading work and automatically stopping by securely detecting even a slow movement of the vehicle due to inclination of a road surface or the like in a short distance. SOLUTION: When a time interval ΔTn+1 of a pulse signal of a car speed sensor gets longer than the previous time ΔTn (Step S55), a count value of a first counter is reset (Step S60). If the generated pulse signal is caused by swing of a vehicle due to loading work or the like, the time interval of the pulse signal gets longer with decrease of the swing, and the count value of the first counter is reset. In other cases, it is regarded as starting of the vehicle, and the number of pulses continues to be accumulated without being reset.

Title: Golf club
Inventor: MURAKAMI NOBUHIRO
IPC: A63B53/12
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To allow an ordinary powerless average-level golfer to swing a club through more easily while enabling increase in flying range by setting the bending rigidity at the tip part of a shaft at least equal or higher than that of the residual part of a shaft to make the head speed thereof relatively slow. SOLUTION: In a shaft 1, the bending rigidity is so distributed that the rigidity at a tip portion in a range of almost 200 mm from the tip 1A is made higher as comparable to that of a shaft for advanced level and the rigidity at the remaining portion on the side of the grip backward from near the position 290 mm therefrom is set lower than that at the tip portion. In shooting by a club having a shaft 1 with such a rigidity distribution, the rigidity of the soft rear portion allows even an ordinary powerless player to swing the club more easily to accelerate the head speed at the moment of impact. Moreover, the higher rigidity of the tip part allows obtaining of a powerful hit ball at the moment of impact to facilitate higher flying of the ball thereby achieving a longer run.

Title: Video recording method for double-deck video tape recorder
Inventor: BOKU NITSUCHIYUU
IPC: H04N5/7826
Filed: 1992-06-17
Abstract: PURPOSE: To improve operability by automatically starting a video recording or temporarily suspending mode, according to the mode of another device at the time of providing a synchronizing key to make an own device in an editing and recording mode. CONSTITUTION: At the time of video-recording the reproducing signal of a deck 6 by a deck 10, a key matrix 3 makes the deck 10 in a recording temporarily suspending mode at the same time as pressing the synchronizing key 1 provided for a key matrix 20. Then a microcomputer 4 inputs the signal of the synchronizing key 1, it judges as being in the editing/recording mode, and when the deck is in the state of reproducing, it releases the temporary recording-stop mode of the deck 10, so that the deck 10 may execute recording. On the other hand, when the deck 6 is not in the reproducing state, the temporary recording- suspend mode is held. Thereby editing/recording operation is made smooth, and time is reduced to improve operability.

Title: Semiconductor device
Inventor: SUZUKI HIDEO
IPC: H01L29/73
Filed: 1990-06-16
Abstract: PURPOSE:To obtain a low ballast resistance value without lowering dielectric strength and output power by making thicker an epitaxial layer in a resistance region than that in a base region. CONSTITUTION:An epitaxial layer 2 around a resistance region 7 is processed as a mesa type layer and the epitaxial layer 2 in the resistance region 7 is formed thicker than that in a base region 2 by about l to 3mum. Therefore, even when junction depth XjR of resistance region 7 is set deeper to give a low ballast resistance value to the resistance region 7, dielectric strength can be obtained since thickness te of the epitaxial layer 2 is set to a large value. Meanwhile, in a transistor, thickness te of the epitaxial layer 2 in the base region 3 is set to a small value and therefore an output power is never lowered.
