Title: Fixing roller
Inventor: KON SHUJI
IPC: F16C13/00
Filed: 1993-06-24
Abstract: PURPOSE:To produce the fixing roller which does not generate offset even in the initial period of using a copying machine. CONSTITUTION:An arbor 2 formed with an elastic material layer 3 is inserted into a fluororesin tube and is cured by heating, by which the fluororesin layer 4 is integrated to the arbor.

Title: Exposure of electron beam
Inventor: MATSUURA SHIZUYA
IPC: H01L21/027
Filed: 1979-11-27
Abstract: PURPOSE:To prevent insufficient exposure of microminiature pattern by varying electron beam scanning speed in response to the size of a pattern element when selectively scanning the electron beam on the pattern element forming a predetermined pattern configuration. CONSTITUTION:An output from a computer 1 is applied to a pattern generator 2 and a motor control circuit 8 for controlling a specimen stage 10. When exposing the exposure pattern by decomposing the pattern into pattern elements (rectangular pattern), a function for varying the electron beam scanning speed in response to the size of the pattern element (width of electron beam) is provided at the generator 2, and the scanning speed is decelerated in exposure on the region having small beam width. Since the scanning speed can be thus varied according to the beam width of the element pattern, a sharp drawing pattern can be formed in a short time.

Title: Ink jet recorder
Inventor: MIZUNO TSUNEO
IPC: B41J2/175
Filed: 1979-11-29
Abstract: PURPOSE:To equalize the jet speed of ink from each nozzle by connecting a common ink chamber and a liquid chamber with a piezoelectric element by an ink supply pathway formed in to a plurally bent structure. CONSTITUTION:Ink in a common ink chamber 2 is directed through an ink supply pathway 3 into a liquid chamber whose wall is fitted with a piezoelectric element 4 and then injected in the form of fine particles from top nozzle 7 by means of the contraction of the piezoelectric element 4 in an ink jet recorder provided with a multinozzle type print head.

Title: Electric rice boiling machine
Inventor: MIYAKE KAZUYA
IPC: A47J27/00
Filed: 1988-06-23
Abstract: PURPOSE:To detect the quantity of rice at a gool precision, properly heat a pot corresponding to the rice quantity, and surely prevent blowout by excessive heat or deterioration of taste by lack of heat by detecting the temperature change of the pot at the time of breakage of energization to a rice boiling heater by a temperature detecting means. CONSTITUTION:The titled device is composed of a pot for boiling rice, a rice boiling heater for heating this pot, a detecting means for detecting the temperature of this pot, and a control means for controlling the input to the rice boiling heater. After the rice boiling heater is energized for a predetermined time, energization is broken for a predetermined time for immersion boiling, and after this immersion boiling, substantial rice boiling is performed. For a period of breakage of energization to the rice boiling heater in immersion boiling, if the quantity of rice in the pot is small, the pot is heated by remaining heat after breakage of energization to the rice boiling heater to continue increase of the temperature, while if the rice quantity is large, heat of the pot is absorbed by rice and water in it to stop the increase of the temperature of the pot or decrease it. The temperature change of the pot when energization to the rice boiling heater is broken is therefore detected by the temperature detecting means, and the rice quantity in the pot is determined based on this detection.
