Title: Modifier for soil of excavation
Inventor: IKEMATSU MICHIO
IPC: C09K17/06
Filed: 1995-04-12
Abstract: PURPOSE: To obtain a modifier which can convert excavation soil, sludge, etc., produced from e.g. a site of construction into transportable, reusable or disposable one by using a fibrous material and a hydraulic cement or lime as the essential components. CONSTITUTION: The modifier for soil of excavation is obtained by using a fibrous substance and a hydraulic cement (e.g. usual portland cement) or lime as the essential components. Examples of the fibrous substances used include natural fibers such as cotton, hemp, pulp and wool, regenerated fibers such as rayon and acetate, synthetic fibers such as of polyesters and polyamides and inorganic fibers such as glass fibers and carbon fibers. Among them, ground paper and ground coconut shells are particularly desirable because of their excellent water-absorbing effect. If necessary, this composition may further contain a water-soluble polymer compound (e.g. sodium alginate), a porous inorganic substance (e.g. zeolite), etc. The obtained modifier is useful for works such as oil well drilling, a tunneling work and a construction work.

Title: Semiconductor integrated circuit
Inventor: YAMAMURA TAKESHI
IPC: H01L21/8234
Filed: 1982-06-30
Abstract: PURPOSE:To allow no interference of noises from a digital system and then enhance the resistance accuracy by a method wherein a ground is separated into the ground only for analog system and that only for digital system, the resistor of the analog system is formed as a low density diffused region in a well, and the well is connected to the ground only for analog system. CONSTITUTION:An n<-> type diffused region 32 is formed in the p<-> type well 31, and the region is decided as a resistor R. The well 31 is connected to the ground GNDa exclusive for analog system. It is different from the ground GNDd exclusive for digital system, has no relation to noises generated in a digital system circuit, but serves as a noise absorption port. In other words, digital system noises interfering from a power source VDD come into the well 31 via a region 16, a substrate 11, and a junction capacitor Cj. Further, it is going to interfere in the resistor R, the region 32, via a junction capacitor C'j between regions 31 and 32. But, the noises which have come into the well 31 pass through a p<+> type region 33 and are absorbed toward the ground GNDa, and accordingly the noises do not reach the resistor.

Title: Voltage detecting circuit
Inventor: IGARASHI HATSUHIDE
IPC: G01R19/165
Filed: 1989-04-28
Abstract: PURPOSE:To drastically reduce a malfunction caused from a power source noise by giving a hysteresis characteristic so that the threshold is varied near the power source level when the source shifts to high from low level and varied near the earth when the shift is reverse. CONSTITUTION:MOSFET (Trs) M1, M2 and load elements R1, R2 are connected in series between the power source and the earth, and a Tr M3 is connected between a junction of the Trs M1, M2 and the power source, and a Tr M4 is connected between a junction of the elements R1, R2 and the earth respectively. A node (A) of the Tr M2 and the element R1 is made to be an output of a level detecting circuit, and when the source voltage is low, the node (A) becomes 1, a node (B) becomes 0 and the output V0 is 0. Then, when the source voltage is elevated to be over the threshold, the node (A) becomes 1, the node (B) becomes 0 but V0 is kept on 0. Namely, when the state of node (B) is 1, the threshold is shifted near the power source level and near the earth when the node (B) is 0. With this arrangement, the malfunction caused from the power source noise can be drastically reduced.

Title: Vibration gyro and method of its use
Inventor: KAGAWA YUKIO
IPC: G01C19/5677
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To make a gyro compact by holding a vibrator comprising the detecting electrodes and the driving electrodes on both faces of a ring-shaped piezo-electric body. SOLUTION: A vibrator 8 comprises a piezo-electric body 9 and a plurality of electrodes. The piezo-electric body has the ring shape formed by hollowing a central part of a disc plate made of piezo-electric ceramics, and is polarized by the application of the high voltage in the plate thickness direction. The driving electrodes 6a-6d are installed around the Z axis every 90 deg. and the detecting electrodes 7a-7d are installed every 90 deg. between the driving electrodes. These electrodes are formed by evaporated on both faces of the piezo-electric body 9 in such a manner that the piezo-electric body 9 is held therebetween. This vibrator 8 is supported on a soft material to form the vibration gyro. When the vibration gyro is rotated, the deformation is generated on a node part which is not deformed when the vibrator 8 is not rotated.  The detecting electrodes 7a-7d are installed on the node part, so that the rotary angle frequency is obtained from the output voltage of the detecting electrodes. The starting and detecting frequency is lowered because of the shape of the vibrator 8, and the rotary frequency can be detected with high sensitivity.
