Title: Detector for concentration of trace hydrogen peroxide
Inventor: YOSHIZAWA SHIN
IPC: G01N31/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a detector high in sensitivity and simple by a method wherein a solid coloring agent which is composed of phenolphthalin, of a compound which generates copper ions when dissolved in water and of an alkaline compound is sealed in a translucent container from which oxygen and carbon dioxide are removed. SOLUTION: As phenophthalin, its salt with an alkaline compound is used in an amount which amounts to about 3 to 30μmol/l when a sample is dissolved. As a compound which generates copper ions when dissolved in water, copper sulfate, copper chloride, copper formate or the like is used in an amount which amounts to about 0.03 to 2.8μmol/l of copper ions when the sample is dissolved. As an alkaline compound, lithium hydroxide, sodium hydroxide, potassium hydroxide or the like is used in an amount which amounts to a pH of about 10 to 13 when the sample is dissolved. A coloring agent which is composed of them is sealed into the inside of a glass pipe 1 in the order of glass wool 2, a filtering material 3, glass wool 4 and the coloring agent 5, and a detector is formed. The sample is sucked into the detector so as to come into contact with the coloring agent. Then, when hydrogen peroxide is contained in the sample, it is colored to be a reddish purple color, and it is compared with a color reference so as to be determined quantitatively.

IPC: H04L7/08
Filed: 1995-03-24
Abstract: PURPOSE: To provide a frame synchronization method capable of establishing frame synchronization by using a frame synchronization circuit of a low speed at the time of receiving STM-N signals. CONSTITUTION: At the time of receiving the STM-N signals stipulated by SDHNNI and establishing the frame synchronization, so as to completely specify the bit shift amount of a byte assigning circuit 1, an NU1 byte undefined in an ITU-T recommendation is used in addition to A1 and A2 bytes and the frame synchronization is established in the frame synchronization circuits 3-1 to 3-3 arranged behind a byte separation circuit 2. Thus, since the frame synchronization circuits 3-1 to 3-3 can be operated at an extremely low speed, a synchronization circuit is constituted by using the CMOS LSI technique of small power consumption and also, the operation margin of the synchronization circuit can be taken extremely large compared to the case of using a high-speed frame synchronization circuit.

Title: Flag generating circuit
Inventor: YAMADA HIDEAKI
IPC: H03M9/00
Filed: 1989-03-17
Abstract: PURPOSE:To prevent the production of an erroneous flag by applying a hazard to shift registers of n-stage and using an AND means so as to AND an output of a pre-stage and an output of a final stage. CONSTITUTION:A circuit generating a flag when a signal having a period being a multiple of m (m>2) of a clock period is inputted is provided with an n-stage shift resister 4 shifting the input signal by a multiple of n (n>=m) of the clock period and an AND means 5 ANDing a final stage output of the shift register 4 and an output of an optional stage within from the (n-2)th stage till the [n-(m-1)]th stage. Thus, when a hazard is inputted, it is converted into a pulse with the same period as the clock period at the 1st stage of the shift register 4, the resulting pulse is shifted sequentially by each clock period and an L level AND output is obtained by ANDing the n-stage output and the output from the preceding stage from the (n-2)th stage because of the production of a period over one clock period between the final stage output and the output of the preceding stage before the (n-2)th stage. Thus, the production of an erroneous flag is prevented.

Title: Measuring method for current distribution on metal plate
Inventor: MATSUI TOSHIO
IPC: G01R19/08
Filed: 1980-05-20
Abstract: PURPOSE:To make it possible to simply measure the current distribution on a metal plate by sticking magnetic tape coated with magnetic powder on the metal plate, and after making a current flow through said metal plate, observing the arranged condition of the magnetic powder. CONSTITUTION:Tape 3, which has a surface coated with magnetic powder and a back surface coated with a bonding agent, is stuck on various places on the metal plate 1. When a current flows through the metal plate 1, a magnetic field is generated thereat, so that the magnetic powder is lined up in a given direction affected by the flowing direction of the current. Accordingly, by observing the arranged condition of the magnetic powder on the tape after the current has flowed by using a microscope, or investigating said arranged condition of the magnetic powder by applying a polarized light, the current distribution can be measured. Thereby, the distribution of current flowing through a metal plate can be measured by an extremely simple method.

Title: Method of separately supplying candy piece and its equipment
Inventor: KAWASAKI KAORU
IPC: B65B35/26
Filed: 1980-05-20
Abstract: PURPOSE: To smoothly drop candy pieces which are entered on a rotary move disk by applying a fluid approximate intermittent rotary motion in which rotary stop status does not continue to the disk when the candy pieces are distributed by centrifugal force and dropped separately into a receiving hole on the edge of the disk.  
     CONSTITUTION: When a crank shaft 7 is uniformly revolved, the revolution of the drive gears 9 of an eccentric shaft 10 is transferred to a move disk 1 through decelerated gears 16W18 and a rotary support shaft 3. At the same time, since a link 21 vibrates through a link 20 by the rotation of a crank 8, the angular speed of the move disk 1 perodically changes by the compound rotation. When candy pieces (a) are collectively entered on the move disk 1 in this state, the candy pieces (a) which was not dropped in a receiving hole 2 among the candy pieces (a) which were distributed into a disk periphery by centrifugal force are put on the receiving hole 2 in a bridging form and vibrate when they are transferred in the rotary direction of the disk 1. This accurately drops the candy pieces (a) in the receiving hole 2 and separately supplied to a feed tub.
