Title: Packaging method for food containing allyl isothiocyanate
Inventor: YONEYAMA SATOSHI
IPC: A23L27/10
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To restrict degradation in the taste of food containing allyl isothiocyanate, by packaging such food as wasabi containing the allyl isothiocyanate, which is a hot constituent, with gas-permeable packaging material. SOLUTION: Into a gas-permeable packaging material 1, food containing allyl isothiocyanate, for example grated raw wasabi, is stored. The packaging material 1 is a two-layer structure in which polyethylene film 1a as an internal face is covered with gas-permeable paper 1b. The polyethylene film 1a, internal face, allows the volatile gas of the allyl isothiocyanate, which the wasabi 2 contains, to pass through it, and, further, the use of the gas-permeable paper 1b as an outermost layer makes it possible to seal it by an existing automatic packaging sheet device. By putting the wasabi 2 into the packaging material 1 in such a manner and using it together for raw food, such as sashimi, antibacterial action can be exerted to its periphery by a hot constituent volatilizing from the wasabi 2, unless the packaging material 1 is broken.

Title: Variable liquid pressure pump for vehicle
Inventor: IWATA YUKIO
IPC: B60T8/175
Filed: 1991-05-17
Abstract: PURPOSE:To eliminate a conventionally required relief valve and simplify a device by preventing a rise in the delivery pressure of a liquid-operated pump via the automatic interruption of brake fluid pumping, when the pressure reaches the predetermined level. CONSTITUTION:When a motor is driven, a camshaft 21 in a liquid-operated pump 20 rotates and a plunger 22 reciprocates, thereby pumping up brake fluid from a reservoir 4 or a fluid chamber 53 via a circuit comprising a pipe line 29, a ball valve, a fluid chamber 31, a ball valve 24 and a fluid passage 33. When fluid pressure from the liquid-operated pump 20 rises up to or above the predetermined level during traction control, a cylinder member 23 moves right, due to hydraulic pressure acting on an area difference between the large diameter section D and small diameter section (d) thereof, against the force of a spring 42. According to the shift of the member 23, the plunger 22 is as well shifted right, together with a stopper member. As a result, the contact state of the plunger 22 and camshaft 21 is released, thereby causing the pump 20 to stop pumping brake fluid.

Title: Image forming device
Inventor: SAITO SATOSHI
IPC: G03G21/14
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent the positional deviation of a transferred image by decreasing the processing speed of image forming after finishing primary image transfer and driving a carrying means after detecting a reference position mark when a transfer medium needs large heat capacity at the time of fixing. SOLUTION: A driving motor for an intermediate transfer belt is rotated at a low speed in timing that the specified time 't12' elapses after forming a black toner image is started, and the image forming processing speed at the time of performing secondary transfer and fixing is decreased (for example, to 1/2). After this speed decreasing processing is finished, a mark detection sensor detects the reference position mark. When the detection signal is inputted into a control part, a resist roller is driven in timing that the specified time 't3' elapses after the detection signal is inputted. Thus, a toner image (color toner image) on the intermediate transfer belt is secondarily transferred to the transfer medium at the position of a secondary transfer roller.
