Title: Acoustic volumeter
Inventor: IMANISHI MASANORI
IPC: G01F17/00
Filed: 1992-12-16
Abstract: PURPOSE:To accurately measure changes in effective capacity caused by thermal expansion due to temperature changes by making the coefficient of linear expan sion of an acoustic pipe small relative to that of a container for measurement. CONSTITUTION:The coefficient of linear expansion of a subject 11 for measurement is alpha1 and the coefficient of linear expansion of an acoustic pipe 13 is alpha2, and by selecting the material of the acoustic pipe 13 so that alpha1>alpha2, change (DELTAV/V) in measured value =3DELTAT(alpha1-alpha2)>0 where V is the capacity of the subject 11 for measurement and DELTAT is temperature change; i.e., the measured value varies in the same direction as change in effective capacity. Further, by selecting ceramics so that the coefficient alpha2 of the acoustic pipe 13 becomes a very small value, (DELTAV/V)=3DELTAT(alpha1-alpha2)=3alpha1DELTAT (DELTAV/V), and a rate very close to change (DELTAV/V) in effective capacity can be exhibited. Therefore, measurements can be made including change in effective capacity caused by thermal expansion due to temperature change, so a volumeter of very high accuracy can be obtained.

Title: Air belt device
Inventor: UCHIUMI HIDETOSHI
IPC: B60R21/18
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To enhance the restraining performance of an occupant by generating a sufficient tension in a belt when an air belt device is actuated without using a pretensioner. SOLUTION: When an inflator 11 generates a high pressure gas at collision of a vehicle, a cylinder 23 installed at a buckle housing 21 of a buckle device 9 sinks relatively with a piston 24 furnished at the top of an anchor member 25 whose bottom is fixed to a seat base 10, so that a tension is generated in a belt 6 leading to a tongue device 8 coupled with the buckle device 9, which heightens the restraining performance of an occupant. If the gas flow-in port 23 of the cylinder 23 is put in communication with the gas flow-out port 23 owing to the relative movement of the piston 24 with the cylinder 23, the high pressure gas from the inflator 11 is supplied to a bag 12 accommodated inside the belt 6, and the bag 12 is inflated.

Abstract: PURPOSE:To make data which are high in use frequency reside at all times by providing a cache memory system with plural storage areas and storing at least part of address information, used to access a main storage, in the respective storage areas. CONSTITUTION:On a 1st cache memory 22, data stored in a tag memory 10 and a 1st data memory 12 are rewritten on condition that data corresponding to address information is not stored in the 1st data memory 12 when the address information is generated.

Title: Production of easily opening sealed vessel
Inventor: AKAZAWA KIYOHIDE
IPC: B65B7/28
Filed: 1989-12-25
Abstract: PURPOSE:To easily open a cover with a smooth peeling feel, always keeping a stable and a high pressure-resistant properties, by sealing a flange provided with numerous fine recesses on the upper face with a sealant layer of the cover materials with adjusted adhesiveness. CONSTITUTION:Numerous fine recesses 4 are formed previously on the upper face of a flange 2. The number of the fine recesses 4 is preferably within the range of 50-50 pieces per cm<2>. The cover material 3 is composed of a material provided with a sealant layer 5 of a mixed composition including both adhesive and non-adhesive properties with the flange 2. When the flange 2 and the sealant layer 5 are laminated and heat-sealed, the adhesive force at the point B contacting the bottom of the recess is relatively weakened, compared with the adhesive force at the point A where a high seal pressure is acting. And hence, on unsealing, the sealant layer at the upper part of the point A is broken at the strong adhesive part and it is broken along the shape at the relatively weak adhesive part. Such two separating patterns continuously progress and it can be opened without any resistance by an cohesive peeling.

IPC: B22D7/06
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a casting apparatus, in which a high purity ingot can be produced and the deterioration of each member can be restrained. SOLUTION: Into a mold 2, in which molten metal 7 is held, inert gas 8 is supplied from a gas tube 5. At the lower end part 5a of the gas tube 5, a plate-like cover 6 is disposed so as to cover the opening part of the mold 2, and on the peripheral ridge thereof, a gap 14 is formed.
