Title: Fuel property detecting device of internal combustion engine
Inventor: MAEKAWA YOSHINORI
IPC: F02D41/06
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To judge fuel properties of the heavy fuel and the mixed fuel of poor volatility as the fuel to be fed to an internal combustion engine with excellent accuracy. SOLUTION: When the cooling water temperature of an internal combustion engine exceeds 0 deg.C (Step S102), and the elapsed time after the engine is started is between TS and TE (Step S103-Step S104), the engine speed Ne after it is not more than the preset engine speed NO in the case of the regular fuel of excellent volatility is integrated (Step S108). A judgment is made whether or not the deviation between the integrated value NT of the engine speed and the integrated value NOT of the preset engine speed (NOT-NT) is larger than the prescribed value of judgment VTH (Step S110). It can be understood whether the fuel fed to the internal combustion engine is as volatile as the regular fuel, and the fuel properties can be judged with excellent accuracy.

Title: Printer
Inventor: KAZAMA YUJI
IPC: B41J5/30
Filed: 1987-12-16
Abstract: PURPOSE:To permit a time-out printing function to operate in an optimum state by enabling a set time for the execution of printing data in a buffer memory to be freely selected when the transmission of data from a host is interrupted. CONSTITUTION:CPU for a controller and a driver 2 executes an interrupt routine each time a single piece of data is processed. First the CPU receives a single piece of data from a host computer 14 and stores the data into a buffer. After this, the CPU reads the value of data of a specific address RAM 10 that is set by means of command set routine, and multiplies the value by a value of reference time. This value obtained becomes real-time information for time for setting a time-out. Next, after this, the CPU sets this real-time information in a timer and permits the timer to be started, returning to a main routine. The CPU starts the timer each time the interrupt processing is performed as described above. For this reason, if the transmission of data is interrupted until the timer passes a set time, the time is out. In this way, a time-out printing control can be carried out by giving any set time.

CONSTITUTION:The magnet roller 50 is installed at the inside of the photosensitive drum 40 and on the position corresponding to the exposure position Ex. To put it concretely, the columnar magnet roller 50 is rotatably supported along the axial direction of the photosensitive drum 40. The magnet roller 50 is bisected into parts such as an N pole and an S pole, and the roller 50 is arranged so that the outer peripheral surface may be opposite to the inside surface at the exposure position Ex of the photosensitive drum 40. When the magnet roller 50 is rotated and driven at a speed higher than that of the photosensitlve drum 40 in the direction B opposite to the photosensitive drum 40 moving direction, an electric field is generated by electromagnetic induction and an overcurrent is generated on the exposure position Ex of the photosensitive drum 40. Thus, the exposure position Ex is heated by the overcurrent in a non-contact state, so that the temperature of the exposure position Ex rises higher than the other surface parts of the photosensitive drum 40.

Title: Pressure swing adsorbing method and apparatus
Inventor: HORII YUJI
IPC: B01D53/04
Filed: 1990-11-22
Abstract: PURPOSE:To recover two component gases with high purity by recovering the second component gas by adsorbing the first component gas easy to be adsorbed by a specific adsorbent and replacing and removing the residual impure gas in an adsorbing tower before recovering the first component gas by desorption under reduced pressure. CONSTITUTION:Both of the first component gas easiest to be adsorbed by a specific adsorbent and the second component gas hardest to be adsorbed by said adsorbent are recovered from raw material gas containing at least two components. At this time, in an adsorbing process, the raw material gas is introduced into adsorbing towers 10a, 10b packed with the adsorbent to adsorb the first component gas and the second component gas is taken out of the outlets of the adsorbing towers as a product. In the next cleaning process, the gas based on the first component gas is introduced into the adsorbing towers to remove the impurity gas in the adsorbing towers. Further, in a desorbing process, the adsorbing towers are reduced in pressure to desorb the first component gas to recover the same as a product. As a result, two component gases can be easily recovered from the raw material gas with high purity.

Title: Impression pressure adjustment mechanism of printing device
Inventor: SENBA SHINJI
IPC: B41F17/36
Filed: 1987-12-16
Abstract: PURPOSE:To permit printing adjustment to be performed in a short time without labor and thereby improve operability with manpower saving by spirally inserting a vertical screw shaft supported vertically on a machine body side with restrictions into a screw hole on a support member and, at the same time, a rotary drive device for the vertical screw shaft and a detection means to detect the number of rotations of the rotary drive device. CONSTITUTION:If an impression pressure is increased, a motor 21 is started after the setting of the number of rotations corresponding to a desired impression pressure to a detector 29. Then a screw shaft 24 rotates through a belt 26, and a receiving table 27 slightly lowers by screw action of a screw part and a screw hole 27b. At the same time, the motor 21 stops by detection of the set number of rotations by the detector 29 and the lowering of the receiving table 27 stops. Consequently, the impression pressure of a transfer roller 7 against a semiconductor device 10 increases to a specified impression pressure level. If the reduction of the impression pressure is desired, the motor 21 is reversed. As a result, the screw shaft 24 rotates, causing the receiving table 27 to rise to a set position. Concurrently, a mark head 4 is pushed up slightly to decrease the impression pressure.
