Title: Detecting device for strand of granulating equipment
Inventor: SHINDO HIROHIKO
IPC: B29B9/06
Filed: 1988-01-11
Abstract: PURPOSE:To enable the title device to cope immediately with a situation at the time of cutting, by a method wherein passing of a strand is detected with a stationary roller and movable roller, a rotation of the roller is detected with a rotation detecting sensor and reflector and a detected result is applied to an instrument in a central monitoring chamber. CONSTITUTION:At the time of the normal operation, a movable roller 16 and stationary roller 17 are turned by passing a strand 5 through a strand detecting part. Rays to be emitted through a rotary detecting sensor 19 are reflected continuously through a reflector 20 during rotation of the movable roller 16, therefore, it is known that the roller is moved by stretching the strand continuously in a row. In the case where the strand 5 is cut off, as the strand does not turn rollers each of the strand detecting part, a matter that the movable roller 16 is not rotating is sent to a central monitoring chamber through a signal of a rotation detecting sensor 19. An alarm 21 mounted within the central monitoring chamber breaks out an alarm by detecting a signal of suspension or disorder of a period of the roll. As the title device can detects disconnection of the strand at once and cope immediately with a situation, a loss of a product can be controlled to the minimum.

Title: Electron gun and electron tube provided with electron gun
Inventor: NAKANISHI TOSHIO
IPC: H01J29/48
Filed: 1994-01-18
Abstract: PURPOSE:To effectively suppress undesired electron emission by forming a nitride film having an electric insulation property in the neighborhood of an electron beam passing opening pore of an electrode in the neighborhood of a cathode. CONSTITUTION:Nitride films 40 and 42 are formed in the neighborhood of electron beam passing opening pores 18a and 20a of electrodes 18 and 20 in the neighborhood of an electron emission layer 14 of a cathode 17. Thereby, since deposition parts 18b and 20b of an electron emission substance such as barium, etc., from a layer 4 are deposited on films 40 and 42, no electron is supplied very short time after the initial electron emission ends and stray electron emission ends rapidly. Consequently, grid emission can be suppressed to a very minute quantity.

Filed: 1986-01-13
Abstract: PURPOSE:To eliminate the need for the generation of a filter output to all-circuit faults by outputting an oscillation pulse having a level over a setting value of a level detection circuit only when a pulse signal frequency of an input circuit is a prescribed frequency or below. CONSTITUTION:When an input signal e1 to a base of a transistor (TR) Q11 of a low pass filter circuit 10 goes to an L level, the TR Q11 is turned off and an H level is outputted from the collector side. When the frequency is a low frequency in a degree that the duration time of the H level output is larger than an integration time constant C11.(R11+R12), the level of the anode reaches a gate voltage Vg1 of a programmable unijunction TR PUT 12, which is turned on, an oscillation pulse Vp having a level over the setting value Vth of a level detection circuit 13 is generated at the cathode of the PUT 12 and a pulse is generated at the output side of the circuit 13. On the other hand, when the input signal is a high frequency input signal e1, since the voltage at a point (b) does not reach the voltage Vg1, the PUT 12 is not conducted and no pulse is generated.

A secondary heat flow β is generated along the upper surface of a straightening vane 9 after flowing the heat flow through the gap S downward at the portion where the recessed parts 2a' and 2b' are located and the second heat flow βmerges with the primary heat flow α to reach distant part.  At the portion without the recessed parts 2a' and 2b', the secondary heat flow β is not generated being stymied by a cooking object and the heat flow reaches only short distance. The heat distribution is equalized by arranging the recessed parts 2a' and 2b' on both side walls 2a and 2b.
