Title: Hot roll excellent in surface roughing resistance and wear resistance
Inventor: KOIDE TARO
IPC: C22C38/34
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To produce a rolling roll, which has excellent wear resistance and in which the formation of mill scale due to the oxidation of the roll itself is inhibited and surface roughing resistance is improved, by constituting the outer layer of a hot roll for steel stock by the use of a high carbon, low alloy steel of specific composition. SOLUTION: The hot roll is manufactured by using a low alloy steel material, having a composition containing, by weight, 0.8-2% C, 1.5-3% Si, 8.0-15% Cr, 0.5-8% Mo, 1-5% V, 5-10% W, 1-5% Nb, and 3-10% Co. The hot roll is integrally formed by using the same low alloy steel material, or the hot roll is a composite roll in which only outer layer is composed of the same low alloy steel material. Then, heat treatment, such as hardening and tempering, is applied to the resultant cast roll to form the desired structure and hardness. By this method, the rolling roll, containing hard metal carbide, excellent in wear resistance, and minimal in the occurrence of surface roughing caused by the formation of mill scale on the roll surface and its attendant peeling-off of the mill scale during use, can be obtained.

IPC: H01L29/78
Filed: 1982-11-05
Abstract: PURPOSE:To restrain the variation of threshold voltage even to a short channel length of a sub-micron region by providing at least one of a source and a drain on a material which has an effective specific inductive capacity less than a specific value. CONSTITUTION:The materials having a specific inductive capacity lower than that of a semiconductor substrate or the effective specific inductive capacity, e.g., polymer films 3 and 4 particularly having the specific inductive capacity smaller than 3.9 are provided immediately under the source 1 and the drain 2. At this time, a back bias voltage is absorbed to this part, therefore a depletion layer is not formed, the threshold voltage becomes difficult to decrease in the short channel; accordingly it is extremely effective to manufacture a finely formed LSI.

Filed: 1990-07-20
Abstract: PURPOSE:To prevent a color image having an undesired color from being formed and to prevent unexpected number of sheets where an image is formed from being outputted by providing a correction discriminating mark on the bar code of a mask original plate and reading it by a bar code sensor. CONSTITUTION:An aligning mark 105 for aligning, a monochromic image 106 which is color-separated and a bar code 108 which is printed within a length l from the trailing edge of a paper 107 and which shows the color of exposing light and the number of outputted sheets of the color image are printed on the mask original plate 15. The correction discriminating mark Pb is provided on the bar code 108.

Abstract: PURPOSE:To control heating under a condition that the effect of the noise of microwave is excluded, and improve the finish of cooking, by a method wherein the driving of a microwave supplying means is stopped to correct a desired temperature when a detecting temperature has arrived at a temperature of low value, which is lower than the desired temperature by a predetermined temperature, while the driving of the microwave supplying means is started again and effected until the detecting temperature arrives at a corrected temperature. CONSTITUTION:When a detecting temperature has arrived at a low value temperature Tt, lower than a cooking finishing temperature T0 by a predetermined temperature 5 deg.C, microwave heating is stopped, and a predetermined time of 5 sec is set in a timer (TM). When 5 sec has elapsed, a flag F1 is set.

Title: Noise signal removing circuit for magnetic type crank angle sensor
Inventor: NISHIYAMA SHIYUUJI
IPC: G01D3/00
Filed: 1982-11-04
Abstract: PURPOSE:To prevent erroneous detection of a crank angle, by providing a mask circuit, which prevents input of the detected signal of a magnetic crank angle sensor into a signal processing circuit, which outputs a timing signal, for a specified time from the start of the engine of an automobile. CONSTITUTION:When an engine is started, a starter signal ST, which is applied to a buffer B through an input terminal IN, is changed from a 0 to a 1. When the signal ST is a 0, the output signal level of the buffer B is VL. When the signal ST is a 1, the output signal level is VH. Therefore, an output signal (e) of a voltage comparator COM becomes a 1 for a specified time from the rise up of the signal ST. Then a transistor (TR) Q is turned ON. Therefore, a detected signal (a) of a magnetic type crank angle sensor 6 is grounded through the TRQ. Even though noise signals are superimposed on the signal (a) at the time of the engine start, the noise signals are not inputted to a signal processing circuit 7 because of a mask circuit 8, and the erroneous detection of the crank angle can be prevented.
