IPC: A61L9/015
Filed: 1988-06-07
Abstract: PURPOSE:To efficiently purify air by a method wherein room air is introduced into an ozone generator after dehumidification to form ozone and air is brought into contact with said ozone and, after excessive ozone is decomposed, the treated air is dehumidified, deodorized and enriched with oxygen. CONSTITUTION:In order to remove not only humidity but also suspended fine particles (especially having a particle size of 0.5mum or more) in room air, a membrane filter wherein two or more membranes having different pore sizes are combined is used. At this time, by properly selecting a membrane, a part of nitrogen in air is caught to concentrate and enrich oxygen. The air wherein both humidity and suspended fine particles are removed is introduced into an ozone generator to be subjected to the formation of ozone. Unutilized air is brought into contact with the formed ozone and the odor components in the air are removed to deodorize said air while the generated oxygen is mixed with the deodorized air to enrich oxygen. By this method, purified air dehumidified, deodorized and enriched with oxygen is discharged to a room.

Title: Catalyst deterioration diagnostic system for engine
Inventor: AIHARA MASAAKI
IPC: F02D41/14
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To determine deterioration accurately even when characteristics of air-fuel ratio sensors on the upstream and downstream side are different by determining diagnostic conditions based on operation condition and diagnosing deterioration of a catalyst based on the time for an output value of a rear air-fuel ratio sensor to reach a set value after fuel is recovered from fuel-cut condition when the conditions hold. SOLUTION: An electronic control system determines if diagnostic conditions based on operation condition have held or not, and monitors conditions of fuel injection upon the holding. Deterioration of catalysts 21, 22 is diagnosed based on the time for an output value of a rear air-fuel ratio (RO2) sensor 31 in downstream of the catalysts 21, 22 to reach a set value after fuel is recovered from fuel-cut condition. That is to say, the fuel-cut at deceleration, etc., during vehicle running is focused, and thus large amount of oxygen is stored in the catalysts 21, 22 by their oxygen storage performance during fuel-cut, however, the amount of oxygen stored decreases due to deterioration.  Therefore, the time for the output value of the RO2 sensor to reach the set value becomes longer along with progress in deterioration of the catalysts 21, 22, and catalyst deterioration can be diagnosed accurately based on this time.

Title: Phase locked loop oscillating circuit
Inventor: YASHIKI MINORU
IPC: H04L7/033
Filed: 1989-05-31
Abstract: PURPOSE:To reduce fluctuation in an output frequency even when a reference clock signal whose phase is changed is inputted by controlling the circuit so that the phase of a reference clock signal after a phase change and a phase of the outputted clock signal from a frequency divider are synchronized when the phase change in the reference clock signal is detected. CONSTITUTION:When a reference clock signal S1 is abnormal and the reference clock signal S1 whose phase is shifted by +90 deg. is sent to a phase comparator 9, a counter (1)14 gives no output and since the phase is deviated by T+t2 of above from the usual phase, a counter (2)15 outputs a pulse S13. A pulse width conversion circuit 18 converts the pulse width of a signal S15 of an AND gate 17 to generate a signal S16 whose pulse width is 1/4T, the signal is fed to frequency divider 12, which is cleared. The frequency divider 12 restarts the frequency division when the pulse of the signal S16 is lost and the phase of the output signal S5 is synchronized with the phase of the reference clock signal S1 after the phase change.

Title: Traveling distance detecting device
Inventor: WATANABE TADASHI
IPC: G08C19/36
Filed: 1995-06-06
Abstract: PURPOSE: To provide a traveling distance detecting device which can detect the traveling distance of a traveling object with high accuracy from the unit of distance displayed on an odometer. CONSTITUTION: In a picture processing section 8, an arithmetic section 9 converts the output signal of an image pickup element into signals which can be processed by a collating section 11. The collating section 11 discriminates each numeric pattern shown by the signals by comparing the numeric patterns with numeric patterns from '0' to '9' stored in advance in a memory 10. The accuracy of a traveling distance signal is improved by dividing the interval between a currently displayed numeral and the next displayed numeral into (n) equal parts and collating the numeric pattern.

Title: Printing apparatus
Inventor: SHIBATA FUMIHIRO
IPC: B41J13/26
Filed: 1987-06-05
Abstract: PURPOSE:To make printing density uniform over the entire printing medium by providing a control means which controls a printing means to change printing density in accordance with outputs of distance between the printing means and a medium to be printed. CONSTITUTION:When printing density is normal, a signal 54 corresponding to the printing density of printed characters is output to one of input terminals on a comparator 707 by entry of a signal from a CCD sensor to an operational amplifier 706. The comparator 707 transmits a signal 56 which shows an H level by time exceeding a reference value 55 to a programmable timer 702 by comparison of the levels of the signal 54 and the reference value 55, and counts the number of pulses N1 of clock pulse by time corresponding to the H level of the signal 56. Then the comparator issues a command for printing with an impression force as it is, and, when printing density is low, counts the number of counts N2 which is equivalent to a lower value than the number of counts N1. After this, the comparator issues a command for increasing the impression force of a printing head 31, and consequently, the impression force of the printing head 31 increases. Thus it is possible to make printing density uniform over the entire range of a printing medium such as a pass book and improve the resolution of characters printed.
