Title: Semiconductor device, and its manufacture
Inventor: MARUO YUTAKA
IPC: H01L21/336
Filed: 1992-12-14
Abstract: PURPOSE:To get a semiconductor device high in yield and reliability by accumulating a gate electrode layer on a semiconductor substrate. CONSTITUTION:A polycrystalline silicon film 208 is accumulated all over the surface, and p-type ions are diffused into the polycrystalline silicon film by heat treatment. At the same time, a partial area 207a of a source or a drain and an element formation area 207b to connect with a silicon substrate are made high-concentration impurity areas. And, patterning is performed by a photoetching method, and then the etching of a gate electrode material is performed to form a gate electrode 208, and besides the gate electrode of a MIS transistor and the gate electrode material connected with the silicon substrate are left. Even if charge occurs by ion implantation, since the gate electrode 208 is connected to the silicon substrate, the charge flows to the silicon substrate through a gate electrode material and the element formation area 207b. For this reason, the gate insulating film 105 under the gate electrode never causes breakdown of insulation.

Title: Method and device for measuring contour of article
Inventor: ROBAATO JIYON FUIIDAA
IPC: G01B21/20
Filed: 1989-12-22
Abstract: PURPOSE: To inspect a curved article with high sensitivity and accuracy by scanning the surface of the article with a sensor head having chips and a probe which are brought into contact with the surface along a prescribed path. CONSTITUTION: When the two contact chips 12 of a sensor head 10 stop on the surface 11 of a segment at a distance S, the chips 12 draw a chord 14 having the length S of a circle of R in radius. A third contact point has the freedom of moving in the direction perpendicular to the surface of an article to be measured and can be given by means of a probe 15 attached to the head 10. When the probe 15 is on the straight line between the chips 12, an arbitrary recessing and projecting section of the surface 11 displaces the probe chip to the upper or lower side of the chord 14 by a distance (h). When the probe 15 is at the exact center between the chips 12, a rectangular equilateral triangle having sides 1/2 S, R-h, and R is formed. Since the length S is known, the decision of the radius R only depends on the value of the distance (h) continuously given by the output of the probe 15.

Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication unit with a high communication efficiency that uses a communication channel when noise is produced in the communication channel. SOLUTION: When the level of a reception electric field strength signal RSSI of a communication channel (n) is a set level Vr or over, communication channels are scanned. When the number of the communication channels is a set number Nr or over, it is discriminated that the communication channel (n) is a communication channel used by an SS system wireless communication unit or a communication channel in which noise is produced, and the wireless communication unit uses the communication channel (n) to conduct its communications.  In the case that the level of the reception electric field strength signal RSSI is lower than the set level Vr before the number of the channels reaches the set number Nr, it is decided that the communication channel (n) is used by another wireless unit whose frequency bans is narrower than that of the SS system wireless communication unit, and the communication channel (n) is not used. Furthermore, in the case that it is decided that the communication channel (n) is not usable, a new communication channel is selected based on the history of the reception electric field strength signal RSSI of each communication channel.

IPC: B65H43/02
Filed: 1993-12-28
Abstract: PURPOSE:To detect running-out of a roll sheet at early timing by controlling a conveyance means and a roll sheet feed means according to combination of the condition of a sheet detection means provided in a sheet conveyance section with a roll sheet feed section. CONSTITUTION:When a timer means 14 sends out a roll sheet 1 from a roll sheet feed section 4', it judges that there is no remaining amount of the roll sheet 1 and displays it, when a roll sheet feed detection sensor 13 continues to output an off signal for a predetermined period of time after the timer is started. Also, when a speed detection means 15 sends out the roll sheet 1 from the roll sheet feed section 4' and the number of revolutions of a motor M is constant, feed-out speed V1 becomes higher if the diameter of the roll sheet 1 is large, and speed V2 becomes lower if the roll sheet 1 is consumed and its diameter becomes small. Therefore, it judges that the remaining amount of the roll sheet 1 is small when the speed V2 drops below a predetermined speed and gives an alarm for it for display.
