Title: Air-fuel ratio controller for internal combustion engine
Inventor: ISHIDA KAZUMI
IPC: F02D41/14
Filed: 1991-10-02
Abstract: PURPOSE:To execute precise emission control, even after a start of the catalytic deterioration, thereby giving the performance of the catalyzer to its maximum, and, in case the catalyzer is so deteriorated that the situation can no longer be left as it is, to precisely judge the situation to execute the prescribed treatment like an alarm. CONSTITUTION:In a double O2 sensor system, a raw value V3 of a second O2 sensor is used for the correction of the feedback control, while a raw, output voltage V2 of the second O2 sensor 13 is used for the judgment on the deterioration of a catalyzer. 1 Accordingly, by using the raw value V3, the feedback control can be executed without being biased onto an over-rich side or over-lean side, thereby giving the purifying performance of the catalyzer to its maximum even after a start of the deterioration of the catalyzer. In addition, by judging the state of the deterioration of the catalyzer by employing the raw value V2, the degree of deterioration can precisely be judged.

Abstract: PURPOSE: To accurately judge defective printing by picking up patterns on a web-shaped body, which runs to undergo repeated printing, detecting and storing an outline density difference and a black density, comparing the density differences with stored density differences one by one, and passing a judgement of defect when the density differences exceed set values. CONSTITUTION: An image pick-up unit 1 picks up a standard pattern to provide a unidimensional picture, a picture generating unit 2 provides a two-dimensional picture, an edge detecting unit 3 extracts a density difference between pixels spaced a distance from each other, and an outline density difference for a single screen is stored in an edge memory 4 while successively shifting positions of pixels. Two original pixels, of which an outline density difference is extracted, are simultaneously inputted into a black density detecting unit 5 to be judged in density through comparison with a black density set value, and a result of detection for a single screen is stored in a black density memory 6.  Subsequently, a pattern being inspected is picked up to be made a two-dimensional picture, and an outline density difference is obtained in a similar manner, so that a difference between it and an outline density difference stored in the edge memory 4 is found by an density difference comparison unit 8 for detection.

IPC: G10F1/02
Filed: 1993-10-13
Abstract: PURPOSE:To obtain a touch which is close to that of an acoustic piano by arranging springs between keys and hammer devices while varying their elastic forces in pitch order. CONSTITUTION:The keys 11 are arranged in the pitch order so that each key has one end supported on a chassis 12 as a fulcrum and the other end freely swings up and down; and a hammer 13 having sufficient mass is arranged below the key 11 so that it can swing around a nearly center part 14 as a fulcrum associatively with the push-up operation of the key. Further, the springs 15a-15e are extended between the hammer 13 and keys 11 so that they are energized in return directions. The springs 15a-15e are equal in width B and length C, but different in plate thickness D; and the spring 15a is the thickest and the springs decrease in thickness in the order of 15b15e. Thus, the plate thickness D is reduced to decrease the elastic reaction forces of the springs 15b-15e, and the pressing force to the keys 11 becomes less. Namely, the springs 15a-15e are arranged varying in elastic force in the pitch order.

Title: Resistance pressure sensitive tablet and its pen-on detection method
Inventor: YOSHIKAWA OSAMU
IPC: G06F3/045
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To provide the detection method which can set the pen-on detection threshold of every resistance pressure sensitive tablet and can decide the pen-on in a state the contact resistance is satisfactorily reduced. SOLUTION: The reference detection voltage VCC is applied to one of both sides of a detection voltage applied resistance plate via the control resistance RP, and the other side of the resistance plate is grounded. The voltage drop due to the RP referred to as the 1st potential difference VA is compared with the voltage drop due to the contact resistance (r) referred to as the 2nd potential difference VB. Thus the resistance value can be compared with each other between both resistance RP and (r). The pen-on detection threshold VTR decided by the difference VA can be easily set when the resistance value of the RP is set equal to the threshold (contact resistance threshold rc) that is optimum to decide a pen-on state.  Then it is possible to decide the pressing of the resistance plate when the resistance (r) is equal to the threshold rc without being affected by the plate pressing position, if the pressing of the resistance plate is decided to be the time when the difference VB is less than the threshold VTR after they are compared with each other.

Abstract: PURPOSE:To shorten the original point resetting time by moving an arm of a robot toward an area of the opposite side based on the result of detection to decide whether the arm is presently kept at one or the other side of the original point. CONSTITUTION:A base 1 is provided with a photointerrupter 6 serving as an original point position detection means, and a light shielding plate 7 is attached to a slider (arm) 3. Thus the plate 7 enters between the light projecting and receiving elements of the photointerrupter 6 and cuts the light. Thus the photointerrupter 6 detects the slider 3 having reached the position of the original point. Meanwhile an approximation switch 8 is provided in a left half of the movable range of the slider 3 and functions as a present area detection means which detects whether the slider 3 is kept in the right or left area centering on a boundary. In an original point resetting state, the present area detection means detects whether the arm 3 is presently kept at one or the other side of the original point position. Based on this detection result, a drive source is driven in the forward or reverse direction. Thus the original point resetting time is shortened.
