Title: Measuring device for surface roughness
Inventor: KOJIMA TOUSAKU
IPC: G01B11/30
Filed: 1983-11-16
Abstract: PURPOSE:To take a high-precision measurement without contacting by projecting a pattern from slantingly above the surface of a body to be measured, forming a light section line which sections the image into a light and a dark part from the projection of a straight line part, and calculating surface roughness of the objective body from its shape. CONSTITUTION:A light source 20 is powered on by an illumination power source 32 to transmit light through a fiber bundle 21. Further, the light is collimated by a lens 22 to form an image of a semicircular pattern 23 on the surface 12 of the objective body through an objective lens 24. The light section line which sections the image on the surface 12 into the light part and dark part is enlarged through the objective lens 24 and a lens 25 and made incident to a photodetecting element 29 through a multifiber sensor 26. Then, the signal is amplified by an amplifier 30 and recorded on a recorder 31. The objective body is moved by lateral jogging mechanism 34 and vertical jogging mechanism 35. Consequently, the roughness of the surface 12 of the objective body is measured continuously without contacting.

Title: Air-fuel ratio feedback control for internal combustion engine
Inventor: KUMAGAI SHIRO
IPC: F02D41/00
Filed: 1986-09-12
Abstract: PURPOSE:To judge the reversal of air-fuel ratio always after the lapse of a certain time by determining the delay time on the basis of the response time up to the time when the output of an exhaust sensor reverses the prescribed judgement value from the time point when the air-fuel ratio in the ordinary operation is varied. CONSTITUTION:An electronic controller 16 calculates the fundamental fuel injection quantity on the basis of each detection value of an air flow sensor 14 and a crank angle sensor 22 and performs a variety of correction on the basis of each detection value of a throttle opening degree sensor 19, O2 sensor 21, water temperature sensor 24. etc. In the region where the variation of number of revolution is little after warming, the supplied fuel quantity is sharply varied at each prescribed traveling distance, and the time necessary for the change of the output of the O2 sensor 21 from rich to lean or from lean to rich is measured from the above-described time point, and the delay time is calculated by subtracting said time from the max. allowable response delay time. In the air-fuel ratio feedback control region, reversal of the air-fuel ratio is judged after the calculated delay time after the output of the O2 sensor 21 reverses.

Title: Balancer device in reciprocating engine
Inventor: YONEZAWA TOORU
IPC: F16F15/26
Filed: 1983-11-14
Abstract: PURPOSE:To provide a piston crank mechanism for reciprocating engine with reduced engagement between tooth parts with each other and reduced abnormal wear therebetween by increasing backlashes among a train of eccentric gears and making eccentricities of the gears less than 0.11. CONSTITUTION:When a piston is at top and bottom dead centers in eccentric gears 4, 5, there is produced a state where a pitch circle engages too hardly with the other pitch circle on the way of respective rotations of the gears. When the ratio between the amount of too hard engagement of gears and the diameter of one of the pitch circles is assumed to be a hard engagement ratio, and if it lies in the range from 0-0.11, it is possible to absorb the amount of hard engagement by increasing the amounts of backlashes among the eccentric gears. Hereby, abnormal wear can be prevented from being produced in the balancer part of the piston crank mechanism.

Title: Erasion method of circular arc shift instruction sentence
Inventor: MATSUDA AKIRA
IPC: G05B19/42
Filed: 1983-11-15
Abstract: PURPOSE:To attain the effective use of programs by erasing a circular arc shift instruction sentence after obtaining the coincidence between the circular arc shift instruction sentence as well as two of three points to receive teaching and the teaching data on another point. CONSTITUTION:The teaching is given to a welding line (solid line) 1 between teaching points P100-P109. For instance, a circular arc (broken line) passing teaching points P106-P108 functions as a shift instruction sentence which shifts a welding torch 2. In case the welding point shown by a solid line is shifted with no program change, a write button is pushed with the torch 2 kept at a teaching point P106 to write the teaching data on a teaching point P107. In the same way, the data on a teaching point P108 is written. Therefore the coincidence is obtained among three teaching points P106-108. Then the radius calculated when a program is executed is set at zero. Thus a circular arc shift instruction sentence is substantially erased out of the program.

If a set value of room temperature is in a range between 11 deg.C and 22 deg.C, for example, 18 deg.C, an intermittent operation of a specified rate is performed with a minimum frequency in a range between 11 deg.C and 18 deg.C and the operation is stopped when the temperature is more than 18 deg.C. Even if the set room temperature is 22 deg.C or more, for example, 25 deg.C, the intermittent operation with a specified rate is up to 22 deg.C and the operation with a temperature more than 22 deg.C is stopped. In a range of an intermittent operation, a capability of condensor and a capability of evaporator are selected in such a way as the power consumption becomes a minimum value.
