Title: Food dividing device and method for continuously dividing food by using the device
IPC: B26D3/28
Filed: 1992-03-31
Abstract: PURPOSE:To ensure a given gap during cutting of a food and to improve peel of a food by a method wherein an uneven surface curve is formed on one surface and other surface forms a plane or a curved surface not brought into a interpolation relation with one surface, in a plurality of sheet-form cutting blades disposed in respective division frames. CONSTITUTION:A food dividing device 1 is formed such that a plurality of sheet-form cutting blades 2 are disposed in respective division frames 3. In this case, in the sheet-form cutting blade 2, one surface forms an uneven curved surface continuing in a direction in which a food passes. The other surface forms a curved surface not brought into an interpolation relation with a plane or the uneven curved surface of one surface. During cutting of a food, the sections of adjoining foods 5 and 6 are positioned facing each other in shapes different from each other. This constitution causes the adjoining foods 5 and 6 to approach each other by a distance equivalent to the thickness of a blade when each sheet-form cutting blade 2 is removed, resulting in causing a given gap 7 to remain. Thus, a contact area between the mutually adjacent foods 5 and 6 is reduced and peeling ability is improved.

Title: Production of sintered aluminum nitride having high thermal conductivity
Inventor: ITSUDO YOSHIKO
IPC: C04B35/581
Filed: 1990-03-29
Abstract: PURPOSE:To obtain a sintered aluminum nitride having dense texture and high thermal conductivity by sintering formed aluminum nitride powder without using an assistant and baking the sintered product in reducing atmosphere under reduced pressure. CONSTITUTION:The objective sintered material can be produced by forming aluminum nitride powder, sintering without using an assistant and baking the sintered product in reducing atmosphere under reduced pressure, thereby decreasing the oxygen content in the aluminum nitride crystal particles. A sintered product having high purity and strength and resistant to deformation even at a high temperature can be produced by this process. Since the product lacks grain boundary phase, it has uniform color tone and is producible in improved yield and remarkably increased productivity. The sintered product is preferable to be used e.g. as a bottom plate for the baking of an aluminum nitride product.

Title: Auto-tracking monitor
Inventor: IKEDA TOSHIYUKI
IPC: H03L7/00
Filed: 1988-03-30
Abstract: PURPOSE:To expand a pull in range and to stabilize by feeding-back a signal from an impedance conversion part to a pulse generation part through a feed- back resistance and controlling a pulse width. CONSTITUTION:For example, when a synchronization frequency is made higher, an emitter voltage (v) is made lower, an electric current flowing into a capacitor 3 is decreased by a feed-back resistance 11 and the width of the output pulse of a monostable multivibrator 1 is widened like a broken line from a solid line. When the pulse width is widened, its average voltage is increased. Namely, the emitter voltage (v) is further decreased by the feed-back registance 11, an electric current (i) flowing into a capacitor 9 is increased and a self-travelling frequency is further increased. Consequently, a gain is increased by the feed-back resistance 11. Thus, the synchronization frequency can be accurately followed.

Title: Filling process of gas cubicle with gas
Inventor: KUBOKI SHIGEO
IPC: F17C5/00
Filed: 1982-05-13
Abstract: PURPOSE:To discharge air efficiently from a cubicle in a short time using less amount of insulating gas, by introducing said insulating gas through the valve on the lower part of said cubicle and discharging air from the valve on the inclined top, and reintroducing the gas after a certain time. CONSTITUTION:In a substitution process in which an insulating gas 3, such as SF6, is introduced in a gas cubicle 1 through a stop valve 2, and the air is discharged at a stop valve 4 on an inclined top 1a, the gas 3 is mixed with air and unsubstituted air remains. After being left for a certain time, the gas 3 with a greater sp.gr. moves downward and the air with a smaller sp.gr. moves upward. When substitution work is resumed at this point, the remaining air is discharged promptly along the angle of inclination 1a, through the valve 4. Thus, the density of gas 3 can be increased in a short time thereby reducing the required gas quantity.

Abstract: PURPOSE:To obtain an AGC circuit which prevents a decrease in reception sensitivity right after reception frequency switching by providing a switching point detecting means and a resetting means, and resetting an AGC voltage to an initial value right after the reception frequency switching. CONSTITUTION:When a knob relating to a reception frequency switch 4 and a switch 15 for detection is rotated by one step in order to a channel where the level of a receive wave (fi) is low, the amplifying transistor (TR) Q1, TRQ2 for differentiation, and switching circuit 14 of a resetting circuit 13 operate by detection information on a switching point which is sent out of the switch 15 for detection to a terminal 12b of the AGC circuit 12 to connect the output side 3b of a filter circuit 3 to a reference potential point. The charged load of the capacitor C1 of the filter circuit 3 is discharged immediately through the reference potential point to attain to the initial value. Consequently, a high frequency amplifier 7 and an intermediate frequency amplifier 9 increase in gain and the gain of a receiving circuit is held constant regardless of an abrupt drop in the level of the receive wave (fi) to prevent a decrease in reception sensitivity right after the reception frequency switching.
