Title: Surface displacement detecting method
Inventor: TAKAMATSU HIROYUKI
IPC: G01N29/00
Filed: 1988-03-09
Abstract: PURPOSE:To improve the detecting accuracy of surface displacement by an acousto- optic measuring method by projecting a laser beam for measuring displacement on the surface of a sample and measuring the laser beam and the interference light of a reference beam having a frequency different from that of the laser beam and its reflecting light. CONSTITUTION:The laser light 2 from an excitation laser 1 is projected on a sample 4 after the laser is intensity-modulated at a frequency (f) Hz by means of an optical modulator 3. On the other hand, laser light of a number of vibration f0 is emitted from a laser 5 for measuring displacement and divided into two parts by means of a half mirror 6. One part of the laser is led to the sample 4 (optical path 1) and the other part is led to a reflecting mirror 8 (optical path 2). The frequency of the reflecting light of the optical path 2 is converted into f0-DELTAf by passing through a frequency shifter 9. Then the interference light of the reflecting light of the optical path 1 and the frequency-converted reflecting light of the optical path 2 is detected by means of a photodetector 7 and the output of the photodetector 7 is passed through band-pass filters 10 and 11 and a multiplier 12. The 2f-component of the multiplied result of the multiplier 12 is detected by a lock-in amplifier 13. Since the 2f-component does not have the phase item which is varied by a disturbance, the 2f-component can be measured with high accuracy.

Title: Fuel injection amount control device for internal combustion engine
Inventor: ABE SHINICHI
IPC: F02D41/12
Filed: 1988-03-09
Abstract: PURPOSE:To obtain the optimum fuel injection time eliminating generation of the air-fuel ratio lean due to a calculation delay by starting calculation of a weighted mean value of an intake air amount by the fast timing when the intake air amount increases its change rate. CONSTITUTION:A control circuit 16 calculates an intake air amount QN per unit rotation being based on outputs of a movable vane type air quantity sensor 2 and a rotary angle (engine speed) sensor 12. While a mean value arithmetic means, when an engine deceleration condition is detected further with the QN not more than a reference value, increases weight of the QN, calculated in the past, calculating a weighted mean value. In accordance with a value of the intake air amount QN, when its change rate decreases to the predetermined value or less, the reference value, determining the calculation start timing of the weighted mean value, is set, and a control means controls a fuel injection valve 8 being based on the weighted mean value of the present intake air amount. Thus even when an undershoot amount changes, the improvement of drivability can be contrived by preventing the overlean and the overrich in the initial period of deceleration.

Title: Controller for toner density
Inventor: URABE KENJI
IPC: G03G15/08
Filed: 1985-03-20
Abstract: PURPOSE:To detect and control invariably accurate toner density by obtaining reference toner density data with a reference developer having constant toner density, calculating the maximum and minimum values and their mean value, and performing toner density control on the basis of those values. CONSTITUTION:The reference developer which has constant toner density is put in a developing device 7 previously and toner density is detected specific times to find the maximum value A and minimum value B, which are stored in a RAM 40. Then, every time an interruption is allowed, the maximum value A and minimum value B are read out to calculate their mean value C, which compared with toner density data D obtained by A/D conversion. Then, when D=C, a solenoid 39 is turned on to supply toner and when D>C, the data D is compared with the maximum value A; when D<=A, the solenoid 39 is turned on and when D>A, the solenoid is turned off. Further, when D<C, the data D is compared with the minimum value B; when D>=B, the solenoid is turned on and when D<B, the solenoid is turned off. Consequently, a reference value for density decision making is given a specific range and invariably accurate toner density is detected and controlled.

Title: Printed matter
Inventor: HIGUCHI SHOICHI
IPC: B42D1/00
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To make spaces between adjacent lines small, increase the amount of information to be contained per unit area and reduce the pages of a printed matter by making different the character direction of character rows between adjacent lines and constituting sentences formed of the character rows of the same character direction. SOLUTION: The directions of character rows are made different between the adjacent lines, for example by 180 deg., and a continued sentence is constituted of the character rows in the same character direction. On a printed matter, one continued sentence is read by setting the printed matter in the normal direction, while the other continued sentence is read by setting the printed matter in the reverse direction. Thus the character direction of character rows is made to be different between the adjacent lines so that readers can recognize unconsciously the difference of the character direction of the character rows between the adjacent lines even when spaces between the adjacent lines are made small.  Thus not only the discrimination of the character rows between the adjacent line can be made easily, but also the amount of information contained in the unit area is increased by the arrangement.
