Title: Method for measuring ph of paper
Inventor: FUJIWARA SHIZUO
IPC: G01N33/34
Filed: 1986-01-10
Abstract: PURPOSE:To make it possible to measure true pH value of paper in a paper preserving state while the hydrolysis of paper by water during pH measuring operation is prevented, by using a non-aqueous solvent as the hydronium ion extracting solvent of paper. CONSTITUTION:A non-aqueous solvent is used as an extracting liquid in order to extract the hydronium ion contained in paper. As the non-aqueous solvent, methanol is used. Extraction is performed by such a method that a definite amount of fine pieces of paper of which pH must be measured is added to the solvent and a sufficient time is taken to elute the hydronium ion. In such a case that the fine pieces of paper of which pH must be measured are contacted with the solvent, paper pieces are removed and water is subsequently added to measure pH. In such a case that paper is directly contacted with the solvent without processing, the solvent is prevented from contacting with the paper and, thereafter, water is added to measure pH. By this method, the true pH of the paper in a preserving state can be measured.

Abstract: PURPOSE:To form a shallow (internal) base region, by implanting gallium ion as acceptor impurity into a second polycrystalline silicon layer, and making gallium diffuse through an insulating layer at the time of diffusion, and form a linked base region connecting an external base region and the internal base region. CONSTITUTION:As acceptor impurity to be implanted into a second polycrystalline silicon layer 18C being an emitter electrode, gallium (Ga) is used in stead of boron (B) which is used in conventional arts. The gallium diffuses (penetrates a thin SiO2 layer), and forms a linked base region in a silicon epitaxial layer G under a thin SiO2 layer 13 between an internal base region 17C and an external base region 19C. Thereby the connection of the internal and the external base regions is enabled, without a long time anneal heat treatment to extend the internal and the external base regions toward lateral direction, and the depth of the internal base region 17C can be prevented from getting deeper.

Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording and reproducing device for accurately detecting the clogging state of a magnetic head, and a method for detecting the clogging state, and a storage medium. SOLUTION: A microcomputer 9 decides whether or not the control voltage of a gain control amplifier 4 inputted from an amplitude detecting part 7 is at a prescribed reference value or more, and decides whether or not an error value calculated in a process for decoding by error correction of a signal quantized in a digital signal processing circuit 10 into the original digital signal is at a prescribed value or more.

Title: Nozzle for atomizing gas and liquid mixture
Inventor: ASAKAWA HIROYOSHI
IPC: B05B7/04
Filed: 1985-01-10
Abstract: PURPOSE:To make the flow rate distribution uniform with a simple and inexpensive modification at the leading end of the nozzle main body by decreasing gradually the diameter of the bent peripheral surface at the inner bottom part toward the downstream side in the atomization direction of a gas and liq. mixture. CONSTITUTION:A convergent bent inner peripheral surface 2 at the inner bottom part of a nozzle main body 1 is formed with plural stages of bent inner peripheral surface parts 2a and 2b so that the diameter may be gradually decreased toward the downstream side in the atomization direction of a gas and liq. mixture. Consequently, the gas and liq. mixture flowing and guided along the bent inner peripheral surface part 2a on the outermost side collides with the gas and liq. mixture flowing toward the bent inner peripheral surface 2b on the one-stage inner side, and receives the outward component force in the radial direction with respect to the axis P of the nozzle. The curvature of the inner peripheral surface parts 2a and 2b is freely set. Accordingly, the density of the gas and liq. mixture in the lengthwise direction of the orifice 3 is freely controlled, and the flow rate distribution is made uniform.

Title: Speed change control mechanism for electronic control type automatic transmission
Inventor: MAEDA HIROAKI
IPC: F16H61/02
Filed: 1985-01-14
Abstract: PURPOSE:To make a failsafe mechanism and an inhibit mechanism compatible while to retard reversing of speed changer even upon reversing of a manual valve under high speed travel. CONSTITUTION:Upon malfunction of electronic control, power is interrupted from first and second solenoid valves 60, 110 to enter into 4th speed shift condition. When shifting a manual valve 40 to 3rd speed, it will enter into same condition with 4th speed shift because there is no corresponding oil path. Upon shifting to 2nd speed range, a high pressure signal from an oil path 9 will function onto 3-4 shift valve 90 thus to enter into 3rd speed shift. While upon shifting to 1st speed range, an oil path 1 will communicated through a shuttle valve 180 with an oil path 10 to function a high pressure signal onto a safety valve B thus to achieve 1st speed shift. Upon shifting to reverse range, a high pressure signal from an oil path 12 will lift 3-4 shift valve 90 while lower 1-2 shift valve 70 thus to achieve reversing.

A transistor 2 becomes off, and welding is ended. Accordingly, when welding has ended, the tip of the wire has no molten metal at all times, becomes a pointed shape, and the following  arc is started very well.
