Title: Three shaft mobile device
Inventor: WATANABE KAZUNARI
IPC: B25J9/02
Filed: 1989-12-26
Abstract: PURPOSE:To reduce the inertial mass in case of shifting a moving member by attaching those of first, second and third driving means to each base, and shifting each moving member via a transfer means. CONSTITUTION:A first driving means 42 shifting a first moving member 22, a second driving means 44 shifting a second moving member 24 and a third driving means 46 shifting a third moving member 34 are attached to each of bases 12, 14. With this formation, when the first moving member 22 is shifted, the second driving means 44 and the third driving means 46 are not shifted together with the first moving member 22, so that the inertial mass in case of moving the first moving member 22 becomes lessened. Consequently, the first moving member 22 can be shifted at a high speed. In addition, even in the case where the second moving member 24 is shifted, the third driving means 46 is not shifted together with the second moving member 24, thus the inertial mass in case of the second moving member 24 shifted becomes lessened as well.

Title: Cushion
Inventor: FUJIWARA MASAKI
IPC: A47C27/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To reduce touching areas of a cushion to a human body to make a cushion excellent in heat insulation and dehumidification and be suitable for using as bedding for a patient, by wrapping a core material formed of a plate honeycomb structure with a number of through holes passing through from surface to back side by a cloth of mesh fabric cover. SOLUTION: When this cushion 1 is used as, for instance, a bedding mat, the cushion 1 is placed between a bed mat or futon and a sheet and suitably placed on a part around from the back to the waist for use. Because a core material 2 wrapped in a cloth cover 3 of the cushion 1 has a plate honeycomb structure, the area touching on skin is small to demonstrate an excellent position distributing function. And, because the core material 2 has a number of through holes vertically passing through, air permeability is excellent and has heat retaining effect since heat energy discharged from a human body is accumulated in spaces of the through holes. Moisture on the skin surface is easily evaporated to prevent wet feeling since those through hole parts are spaces. Consequently the cushion can be used regardless of season all the year round.

Title: Driving signal generation circuit of sense amplifier
Inventor: RI KEIKOU
IPC: G11C11/409
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To improve the speed and stability of the sensing operations of a sense amplifier and reduce the power consumption of the amplifier by driving the sense amplifier by using an external voltage and the output voltage of a voltage generator in the initial stage of the sensing operations in which a large amount of current flows and, thereafter, by only using the output voltage of the voltage generator. SOLUTION: A sense amplifier starts sensing operations upon receiving a signal SPB from a sense amplifier control circuit. Since a signal SPC from the sense amplifier is lower than the output voltage VDD of a voltage generator in the initial stage of the sensing operations, the control circuit outputs a low- level control signal SPB2 so as to drive the amplifier with an external voltage VCC and the voltage VDD. At the point of time at which the signal SPC becomes higher than the voltage VDD, the signal SPB2 becomes higher in level and the amplifier is driven with the voltage VDD only. Therefore, the load of the voltage generator is reduced and the speed and stability of the sensing operations of the amplifier are improved.
