Title: Manufacture of semiconductor memory device
Inventor: NAKAJIMA HIDEHARU
IPC: H01L21/3205
Filed: 1990-04-04
Abstract: PURPOSE:To reduce the lateral size of a memory cell, with the lateral width of the work line on an element isolating region as the thickness of a conductive layer, by forming an insulating layer, whose sidewall is in the shape nearly vertical to the main face of a substrate, on the element isolating region. CONSTITUTION:When a silicon oxide film 3 is etched using a photoresist layer 4 as a mask, the silicon oxide film 3 is made into such shape that the sidewall is nearly vertical to the main face of a substrate. And a conductive layer 6 having polycide structure is made to cover the surface of the silicon oxide film 3 being patterned. With the photoresist layer as a mask 7, the whole face is etched back. Hereby, a sidewall film 6b is left on the sidewall of the silicon oxide film 3 on the element isolating region 2, and the gate electrode 6a of an access transistor is made on the element formation area. The sidewall film 6b is made a non-selective word line. Since the sidewall of the silicon oxide film 3 is nearly vertical to the main face of the substrate, the width of the non-selective word line is made the thickness of the sidewall 6b.

Title: Measuring device of gear root diameter
Inventor: NISHIHARA TATSUTOMO
IPC: G01B21/20
Filed: 1981-06-12
Abstract: PURPOSE:To measure a gear root diameter automatically with high accuracy, by using a detecting part for outputting a variation of the gear root diameter by an electric signal, and a mechanism for moving this detecting part, when measuring the gear root diameter of a gear, a screw rotor, etc. CONSTITUTION:When a measuring instrument 7 for outside diameter position 7 is pushed up by rotation of a gear 1, a motor 10 is driven by a signal of a potentiometer 8, and a moving lever 11 is moved. As the lever is moved, a measuring probe 2 for gear root position goes forward by expanding force of a spring 5. When the measuring probe contacts with the gear root, the motor is stopped by operation of a limit switch 12, and the lever is pressed against the gear by only the spring in a free state. In this case, the gear is rotated, the gear root radius is scanned, and its radius is detected by a differential transformer 4. A gear root diameter of the gear 1 is obtained by averaging each gear root radius.

Abstract: PURPOSE:To enable a preheating condition to be correctly displayed by compact construction further with a low price, by changing the voltage across both ends of a preheating display lamp in accordance with a rapid change to the resistance value in a PTC ceramic resistor so as to vary intensity of illumination of the preheating display lamp. CONSTITUTION:If a key switch contact 3 is closed, the voltage of a battery 7 is applied to glow plugs 4 via a fixed resistor 12 and a PTC ceramic resistor 2 connected in parallel to each other. At initial time of electrification when a resistance value of the ceramic resistor 2 is very small as compared with the resistance value of the fixed resistor 12, the battery voltage is applied to the glow plugs 4 without causing any voltage drop on the half way of supply, thus rapidly heating the glow plugs 4 and increasing their temperature. Here the high battery voltage, being applied to also a preheating display lamp 6 parallelly connected to the glow plugs 4, brightly turns on the preheating display lamp 6. In this way, a preheating condition can be correctly recognized by changing intensity of illumination of the preheating display lamp 6.

Abstract: PURPOSE: To detect a jammed condition of paper before an abnormal printing takes place as a result of the jamming, by a method wherein the movement of the paper is monitored through the output of a generator for a check roller so that a line feed and a jam can be checked.  
     CONSTITUTION: Within the region B wherein pins provided on a sprocket wheel 1 are engaged with feeding holes of the paper 2, the check roller (a rubber roller) 10 fitted to the generator 9 (a small motor) is placed in contact with the paper 2 so as to hold the paper 2 between the roller 10 and a press plate 6. When the pape 2 is fed, the roller 10 is driven by frictional forces, and the number of lines by which the paper is fed is checked. The force of a spring 11 is so set that the plate 6 can be lifted up with a small force, namely, when the paper 2 is jammed, the plate 6 is liffted up instead of breaking the feeding holes of the paper 2. If a micro-switch is provided so that it is operated by a lifting-up of the plate 6, when the paper 2 is partly disengaged from the pins and lifts the plate 6, this condition can be detected instantaneously and the device can be stopped easily.
