Title: Biological reaction vessel
Inventor: FUTABOSHI YUKIHIRO
IPC: C02F3/28
Filed: 1995-05-31
Abstract: PURPOSE: To provide the reaction vessel by which waste water treatment can continuously and stably be performed over a long period and also, the initial cost and running cost of which are low. CONSTITUTION: This reaction vessel 1 consists of an anaerobic tank 2 for receiving waste water that is at first allowed to flow from a sedimentation tank into the tank 2 and an aerobic tank 4 for receiving the treated water that is treated in the tank 2 and allowed to flow into the tank 4. In this vessel 1, when a coarse gas hole diffuser 5 that consists of polyvinyl chloride tubes having gas holes 5a, each of which has a 2 to 8mm diameter and which are arranged at a pitch of 100 to 1,000mm, is placed at the bottom of the anaerobic tank 2, the amount of dissolved oxygen in the waste water is reduced to about 0mg/liter and the oxidation-reduction potential(ORP) value is maintained within the range of -200 to 300mV.  Since clogging of the coarse gas hole diffuser 5 is inhibited from occurring, the waste water can stably be treated over a long period and also, since this reaction vessel 1 has no moving part and the need of overhauling the reaction vessel 1 is eliminated, the running cost of the reaction vessel can be reduced to a lower value.

Title: Profile measuring instrument
Inventor: ENDOU TAKASHI
IPC: G01B7/00
Filed: 1978-10-31
Abstract: PURPOSE: To measure the deformation of a pipe fitting hole in a short time and quantatively without taking off a pipe by detecting the profile of the pipe fitting hole on a pipe plate using change of resistance of magnetic resistance elements at the time of rotation of a permanent magnet.  
     CONSTITUTION: If a permanent magnet piece 2 is rotated by a driving motor 3 where a pipe fitting hole 17a is perfectly round, the magnetic flux of the permanent magnet piece 2 detected by each of magnetic resistance elements 4 1 W4 n  is constant and resistance changes by the same amount continuously. If such change of the resistance is converted into electrical signals a straight line a is obtained. On the contrary, when the internal surface of the pipe fitting hole 17a is corrosive and deformed, the change of resistance of each of th resistance elements 4 1 W4 n  becomes smaller at a layer diameter part. If such change of the resistance is converted into electrical signals a curve b is obtained. Thus, the deformation of the pipe fitting hole 17a can be detected in a short time and quantitively without taking off the pipe.

When a character region where a character display in black exists is detected, the start address and the end address of a picture signal of the character region stored in the picture signal storage area 19a are stored in address storage areas 19b, 19c.

Title: Buffer device of load detector
Inventor: OHIRA SHUJI
IPC: G01L5/16
Filed: 1986-06-12
Abstract: PURPOSE:To suppress the enlargement of the interval between a force acting part and the center of a load detector, by constituting a buffer device so as to surround the load detector. CONSTITUTION:When force acts on an acting part 2, said force successively passes through a Z-axis block 8, Z-axis parallel flat plates 7a, 7b, and X-axis block 3, X-axis parallel flat plates 5a, 5b, a Y-axis block 4 and Y-axis parallel flat plates 6a, 6b and reaches a load detector 1 from flange 1b to detect load. Further, said force is transmitted, for example, to the robot arm, connected to a flange 1a, from the flange 1a. The force component in an X-axis (or Y-axis, Z-axis) direction of the force allows only the flat plates 5a, 5b (or 6a, 6b, 7a, 7b) to bend. The displacement generated by the bending of said flat plates does not change the direction of the force. By this constitution, the buffering function of this buffer device is developed sufficiently to protect a load detector and the buffer device surrounds the load detector and, therefore, the distance between the force acting part in the acting part 2 and the center of the load detector can be shortened.

Abstract: PURPOSE:To improve the cooling power and the magnetic shielding effect by a method wherein a baffle plate of chimney form made of non-magnetic conductor is provided on a cooling unit, and a reactor is provided in the space surrounded by the baffle plate. CONSTITUTION:The baffle plate 7 made of non-magnetic conductor such as aluminum is arranged in chimney form so as to surround the top surface of the condensing part of a condenser 4 encased in a frame 2 installed below the floor of the body 1, and this baffle plate 7 is fixed to the condenser 4 by welding or screwing; besides, a reactor 5 is settled in the surrounded space. The external connection terminals 8 of the reactor 5 can be led out of the baffle plate 7. Since the magnetic flux leaking out of the reactor 5 to the side and lower directions is the alternating flux, eddy currents generate in the direction of cancelling this flux. Rising currents of air generate by the high temperature heating by the reactor 5, and the cooling power increases by the chimney effect produced by the baffle plate 7.

Abstract: PURPOSE: To prevent the breakdown of the gate of a protecting IGFET due to a spike-shaped overvoltage, by connecting a resistor between a constant voltage feed line and the source of the protecting IGFET coupled to an input terminal through another resistor.  
     CONSTITUTION: The gate of a protected IGFET 121 is connected to an input terminal 21 through a first protecting resistor 123. The drain and gate of a protecting IGFET 122 are coupled to the connection node 22 of the first resistor 123 with the protected IGFET 121. The source of the protecting IGFET 122 is coupled to a constant voltage feed line 24 at a connection node 23 through a second protecting resistor 124. Since the source potential of the protecting IGFET 122 is divided by the resistance of the IGFET and the second resistor, the potential difference between the source and gate is reduced. Therefore, the breakdown of the gate is prevented even if a spike-shaped high voltage is applied.
