Title: Magnetic tape driving device
Inventor: UMEGAKI SUNAO
IPC: G11B15/43
Filed: 1988-05-09
Abstract: PURPOSE:To prevent the fluctuation of tension of a magnetic tape caused by a variance of a friction torque of a motor by measuring the friction torque of a reel motor. CONSTITUTION:A reel motor control circuit 10 controls reel motor driving circuits 8, 9 and increases a current applied to reel motors 4, 5 at a time interval which has been determined in advance until a pulse is generated from reel tachometers 6, 7, and measures a friction torque of two reel motors 4, 5. Subsequently, from this friction torque, a motor current value is calculated, and tension of a magnetic tape 1 is adjusted. In such a way, the fluctuation of tension applied to the magnetic tape 1 caused by a variance of the friction torque of the reel motors 4, 5 can be prevented.

Title: Camera
Inventor: MIYAWAKI MAKOTO
IPC: G03B17/30
Filed: 1990-04-27
Abstract: PURPOSE:To smoothly load a film in a state where a film leader part is not caught by the frame of an aperture by obliquely holding a film cartridge until the film leader part is dropped in a position where it is passed through the aperture so that the film leader part is dropped later on. CONSTITUTION:A projecting part 1a which overhangs the upper edge part of a cartridge room 12 and which is set as a holding means makes the straight loading of a cartridge 10 from the lower part of a camera impossible. Then, the film cartridge 10 is obliquely held until the film leader part 11 is dropped in the position where it is passed through the aperture 17 so as to drop the film leader part 11 later on when the film cartridge 10 is dropped in the cartridge room 12. Thus, when the film is loaded, the film leader part 11 is not caught by the frame of the aperture 17 and the film is smoothly loaded.

IPC: C30B15/26
Filed: 1981-07-20
Abstract: PURPOSE:To eliminate the irregularity of strength of a pellet, in granulation due to a screw feeder, by regulating the rotary number of the screw feeder by operating compression molding force form the number of the rotations of a roll to maintain compression molding force constant. CONSTITUTION:In a granulating machine for subjecting a powder to compression molding, the rotary number N of a roll 2 is applied to a function generator 20 to issue a value Wo/N during idle operation. On the other hand, power W of a roll motor 6, the roll rotary number N and the output from the function generator 20 are applied to a net molding force operator 21 to operate (W-Wo)/N. This value is applied to a feeder rotary number operator 23 to determine the rotary number of the screw feeder 4 so as to be coincided with the objective value of a net molding force setting instrument 23. By this control method, the value (W-Wo)/N can be controlled so as to be coincided with the objective  value enen if the roll rotation number is varied and, therefore, the molding force  of the powder is made constant and the strength lowering of a pellet can be  prevented.

Title: Control of idle revolution number of internal- combustion engine
Inventor: ITOU YOSHIYASU
IPC: F02D45/00
Filed: 1982-06-29
Abstract: PURPOSE:To suppress sharp variation of the number of revolution by reducing the integration term in the feedback control to perform a slow control when an engine is cold in feedback-controlling the idle revolution number by controlling the flow-rate of the intake air which detours around a throttle valve. CONSTITUTION:An idle revolution speed controlling valve 26 is interposed in a by-pass passage 24 which is installed so as to detour a throttle valve 18 in an intake passage, and is controlled during idle operation according to the difference between the engine revolution number which is obtained from the output from a crank angle sensor 44 and the aimed idle revolution number by a digital control circuit 54. When it is detected in the control circuit 54 that a feedback condition is satisfied from the cold engine state, the integration term in feedback control is set to a less value during a prescribed time from the start of the feedback control. Thus, the number of revolution is reduced slowly in the slow control and sharp variation of the number of revolution is suppressed.

Abstract: PROBLEM TO BE SOLVED: To hold large rhythm as well as to obtain a highly accurate standstill position of a web in a platen by vibrating a counterweight supported so as to be rotated by a gear of a shaft of a driving cylinder in the opposite direction of a turning cylinder. SOLUTION: While a driving cylinder 10 and a main gear 14 of a web 3 rotate in the anticlockwise direction, a turning cylinder 20 supported by a toothed pinion 29 rotates in the clockwise direction. Similarly, a counterweight 80 supported by a pinion 76 rotates in the clockwise direction. When a connecting rod 50 is pulled to the upstream side, the pinion 29 instantly moves in the anticlockwise direction along the main gear 14 to thereby reduce driving torque consumed by the turning cylinder 20 during this time. However, a rotary arm 70 simultaneously supported by mechanisms 54, 60 to 65 rotates in the clockwise direction, and the pinion 76 moves in the same direction along the main gear 14 to instantly increase driving torque consumed by the counterweight 80.

Title: Production of resin molding
Inventor: SATO MASAHIRO
IPC: B29C39/42
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To shorten a molding cycle remarkably and to obtain resin moldings of a small lot efficiently and economically by a method in which a molding material containing an uncured thermosetting resin the curing reaction of which is accelerated by electromagnetic waves as a main agent is placed in a molding mold through which electromagnetic waves pass easily, and the material is irradiated with electromagnetic waves. SOLUTION: When the vacuum-casting of a molding material is finished, a molding mold is removed from a vacuum chamber to be irradiated with electromagnetic waves. As an apparatus for the irradiation of electromagnetic waves, for example, an irradiation apparatus equipped with a high frequency oscillator for generating microwaves is used appropriately, and of course a high frequency heating device such as a microwave oven for business purposes is used naturally. When the molding mold removed from the vacuum chamber is irradiated with microwaves, the microwaves pass through the molding mold and induction-heat a thermosetting resin of the molding material cast into the mold to accelerate the curing reaction remarkably.  The curing reaction of the thermosetting resin is finished in a short time of several tens of minutes so that a molding which does not need aftertreatment can be obtained efficiently.
