Title: Method and device for cutting off hard brittle material by vibration
Inventor: ISHIKAWA KENICHI
IPC: B28D5/04
Filed: 1978-12-27
Abstract: PURPOSE:To reduce an inertial force to motion and simultaneously and easily cut off and pick up numerous hard brittle wafers, by superposing low-frequency vibration and reciprocation on the workpieces of relatively small weight. CONSTITUTION:A vibrating system comprising a parallel spring 14, a workpiece mounting rest 16 and a vibrator 18 is provided on a sliding rest 11. The sliding rest is reciprocated by a reciprocating drive means at a desired travel in the direction of the cutting edge of a flat cutter 2. At the same time, the workpiece mounting rest 16 and workpieces 5 are vibrated at low frequency in a cutting-off direction by the vibrator 18. A working liquid in which abrasive grains are suspended is continuously supplied from a nozzle 20 to the parts of the workpieces to be cut off while the cutting edge of the flat cutter 2 is thrusted under a cutting-off load upon the workpieces 5. The workpieces are thus accurately and easily cut off as an inertial force to motion remains reduced.

Title: Water-level detector of nuclear reactor
Inventor: ARA KATSUYUKI
IPC: G21C17/035
Filed: 1979-12-13
Abstract: PURPOSE: To obtain the water-level detector which is not influenced by temperature, pressure, velocity of flow of coolant, etc. by providing a heat-generating body inside a metal pipe installed  in the axial direction of the container of the nuclear reactor and thereby detecting the change in  temperature in the axial direction of the metal pipe.  
     CONSTITUTION: The metal pipe 7 is inserted into the container 6 of the nuclear reactor and an electric heater 8 supplied with current by a power source 18 and temperature sensors 9W16 formed of thermocouples numbering (m) are arranged inside the pipe, while each temperature sensor is connected to a device 19 for processing a signal from the thermocouples and judging the water level. The metal pipe heated by the heater 8 is cooled down nearly to the temperature of water at its part in the water because of good heat conduction from the surface of metal, while it retains the temperature close to that of the heater at its part in the air because of bad heat conduction. Accordingly, the distribution of temperature of the metal pipe in the axial direction thereof changes largely at a position corresponding to the water level 20 inside the container as shown by a solid line 21 in the figure. Therefore, the water level in the container 6 is detected by detecting the point by means of the device 19 for processing the signal from the thermocouples and judging the water level.

Title: Communication system
Inventor: NAMIKI JUNJI
IPC: H04B7/212
Filed: 1985-07-22
Abstract: PURPOSE:To reduce the polling period by completing autonomously a poll addressed to the own station to a slave station not desiring a polling at the present point of time. CONSTITUTION:The 3rd slave station uses a reservation slot to send the last three-packet and then stops communication. In this case, since the polling to the 3rd slave station is useless afterward, a registration elimination signal to stop the polling addressed to the own station is sent to the master station autonomously. A (N) of a signal D3(N) depicts it. The master station receiving the signal D3(N) sends the poll signal Ai(k) to the 1st and 2nd slave stations as shown in the right end in figure, the 3rd slave station is skipped and the 4th slave station is polled. Thus, the 3rd slave station is removed out of the poll period automatically.

Filed: 1990-06-22
Abstract: PURPOSE:To enhance a switching speed without lowering reliability by forming an N-channel semiconductor device whose gate length is shorter than the gate length of other MIS semiconductor devices and whose threshold voltage is lower than that of them. CONSTITUTION:At a semiconductor device which is provided with a bipolar C-MIS composite-type semiconductor device 100 and a C-MIS semiconductor device 200, hot electrons are hard to generate when a source potential is raised. By having an eye to this fact, the gate length of at least an N-MIS Tr 103 out of MIS semiconductor devices constituting the device 100 is made short and a switching speed can be increased without lowering reliability. An apparent threshold voltage of a MIS semiconductor device is increased by a substrate bias effect at about 0.7 V. By having an eye to this fact, a threshold voltage of at least the Tr 103 out of the MIS semiconductor devices constituting the device 100 is set low. The switching speed can be increased when a depletion type is constituted as required.

Title: Detecting device for temperature
Inventor: KOJIMA SUZUO
IPC: G01K7/00
Filed: 1979-12-12
Abstract: PURPOSE: To make blocking oscillation generating when temperature exceeds a prescribed value by inserting a heat-sensitive thyristor into the gate circuit of PUT of a relaxation oscillation circuit.  
     CONSTITUTION: The heat-sensitive thyristor 3 is inserted into the gate circuit of PUT2 of the blocking oscillation circuit. In the case when a circuit as shown by the figure is used, for instance, the heat-sensitive thyristor 3 is in the state OFF when the temperature to be detected is low, and the potential of the gate is nearly equal to the voltage of a DC power source 1. Therefore, even when a capacitor 4 is charged, PUT2 does not turn into the state ON since the gate is reversely biased, thereby not making blocking oscillation. When the temperature rises up to a prescribed value, the heat-sensitive thyristor 3 turns into the state ON, the gate of PUT2 is biased by the voltage set by resistors 7 and 8, and the circuit performs blocking oscillation. The heat-sensitive thyristor 3 which is turned into the state ON by the rise of temperature does not return to the state OFF even when the temperature lowers below the prescribed value and thus the blocking oscillation continues. Accordingly, it continues to generate pulse signals at both ends of a load 6 after the arrival of the temperature at the prescribed value irrespective of the rise and fall of temperature.

Title: Binder type carrier
Inventor: SANO OICHI
IPC: G03G9/10
Filed: 1986-07-10
Abstract: PURPOSE:To prevent the flocculation of carriers by magnetic force and to obtain an image having no white lines by specifying the acid value and hydroxyl value of a binder resin to increase the volume electric resistivity thereof. CONSTITUTION:The binder resin of a binder type carrier consisting of at least ferromagnetic powder and binder resin has both the acid value and hydroxyl value. Both the acid value and hydroxyl value thereof are <=50mgKOH/g and the product of the acid value and hydroxyl value is >=1 and <=600. The carrier constituted of the resin, either of the acid value or hydroxyl value of which has the value in excess of 50mgKOH/g, has the possibility to yield the carrier having the large volume electric resistivity in the initial period of prepn., but such carrier has poor moisture resistance and cannot impart the stable electric charge quantity stable for a long period of time to the toner. The carrier prepd. by using the resin of which the product of the acid value and hydroxyl value is the value larger than 600 has low moisture resistance. The moisture resistance is thereby improved and the stable charge quantity is supplied to the toner even at and under a high temp. and high humidity.
