Title: Production of hollow object made of synthetic resin
Inventor: YAMANE YASUSHI
IPC: B29C65/70
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of a molten synthetic resin from the gap between both mating surfaces of both half bodies in producing a hollow object made of a synthetic resin by closing first and second molds to bring the mating surfaces of first and second half bodies to a mutual contact state and filling a bonded part molding cavity with a molten synthetic resin to bond both half bodies. SOLUTION: Respective half bodies 2, 3 have both mating surfaces 4, 5 arranged to both end parts in the peripheral direction of the outer peripheral surfaces thereof so as to extend outwardly from a half body thickness range (a) to be expanded and have a pair of projected edge parts 6, 7 fitted in the recessed parts 9b, 11b of both molds 9, 11. The first half body 2 is held to a first mold 9 by engaging an anchor projected part 8 with an anchor recessed part 10. Before mold clamping, the mating surface 5 of the second half body 3 is set to the position projected from the dividing surface 12 of the second mold 11.
Patent JP-H01157862-A (JP)
Title: Ink jet printer
Inventor: SAKAI HIROAKI
IPC: B41J2/20
Filed: 1987-12-15
Abstract: PURPOSE:To prevent dropping of ink, inclusion of air, drying of the ink or the like from being generated by providing a pressurizing part for pressurizing a magnetic fluid ink, a nozzle formed of a superconductive material, and a magnet for generating a magnetic flux which passes through the nozzle. CONSTITUTION:When a pulse of voltage generated by a voltage pulse generator 9 is applied to a piezoelectric vibrating element 6, a piezoelectric element 5 shrinks in radial directions. Since the element 5 is adhered to a vibrating plate 4, a bending moment is exerted on the plate 4. As a result, the vibrating element 6 is bent to the side of an ink chamber 3, whereby the internal volume of the chamber 3 is reduced, and the pressure in the chamber 3 is raised. Therefore, a magnetic ink incapable of remaining in the ink chamber 3 is pushed out through a nozzle 7 to fly out of the nozzle 7 as a droplet. The nozzle 7 is formed of a normal temperature superconductive material, so that the magnetic flux is caused to pass through a central part of the nozzle 7 while being repelled by the nozzle 7 without making contact with the nozzle 7, under the Meissner effect. Therefore, the magnetic ink magnetized by the magnetic flux is also caused to pass through a central part of the nozzle 7 without making contact with the nozzle 7, like the magnetic flux.

Title: Vacuum cleaner
Inventor: OTSU YASUHIRO
IPC: A47L9/28
Filed: 1991-11-29
Abstract: PURPOSE:To provide a vacuum cleaner which enables the stopping of a motor when a suction port body is lifted from a floor surface or when it is left alone with a simple construction. CONSTITUTION:When an ongoing direction detecting means 7 detects the advance of a suction port body 1, a motor rotates or is reversed. Each time a signal of the ongoing direction detecting means 7 varies, a retriggerable monostable vibrator is closed for a specified time and the motor is made ready to be driven. When the signal of the ongoing direction detecting means 7 does not change, the monostable vibrator is opened and the driving of the motor is stopped. When the suction port body 1 is left alone being lifted, the motor comes to a stop. This enables the prevention of a dangerous state that may be caused when the motor rotates with the suction port body 1 being lifted and when a blade 3 and running wheels continue to rotate and of damages to a floor surface as caused when the motor continues to rotate being left alone.

Title: Tape cassette provided with memory, and data recording/ reproducing device
Inventor: KUROKAWA TOSHIYA
IPC: G11B15/07
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To easily cope with such a case that the number of terminal pins led out from a nonvolatile memory in the tape cassette 1 in increased to, e.g. 5 pins from 4 pins. SOLUTION: The memory 4 is provided in the tape cassette 1. From the tape cassette 1, e.g. five terminal pins 10A-10D and 10Z are led out. The middle terminal pin 10Z, for instance, among five terminal pins is kept in the nonconducting state and is utilized when the cassette with five terminal pins is developed in the future. By this arrangement, the shapes of connectors are unified for both cases before and after the number of terminal pins are increased. When such a mode that the number of terminal pins are increased, appears in the future, the mode setting is carried out by detecting the continuity/ uncontinuity of a middle terminal pin 10Z.

A throttle opening indication value calculating means 38 calculates a throttle opening indication value corresponding to the amount of air passing through a throttle, and outputs the throttle opening indication value to a throttle actuator 5a through a throttle valve driving portion 39 to control the opening of the throttle valve. Since the opening of the throttle valve is controlled by a value corresponding to the theory air-fuel ratio, the air-fuel ratio is suitably maintained.

Abstract: PROBLEM TO BE SOLVED: To perform the display of a high speed and a high contrast ratio in which flicker, beat and crosstalk are small by inverting polarities of a scanning voltage and a data voltage with specific periodicity. SOLUTION: When the number of subgroups is defied as M, polarities of the scanning voltage and the data voltage are inverted with the periodicity of the S times (S is a natural number) of a selection pulse width and also the S is set so that when the integer part of the quatient of M/S is an even number, the remaider (b) satisfies S/b<12 and when the integer part of the quatient of M/S is an odd number, the remaider (b) satisfies S/(S-b)<12. That is, when the integer part of the quatient of M/S is the even number, b/S and when the integer part of the quatient of M/S is the odd number, (S-b)/S are made to express ratios of subgroups whose polarities are inverted as compared with consecutive scans of two times. Consequently, that respective values are larger than a certain fixed value becomes a condition suppressing the flicker.
