Title: Screening of semiconductor device
Inventor: ISHINO MASAKAZU
IPC: H01L21/66
Filed: 1990-08-18
Abstract: PURPOSE:To enable screening time to be reduced and production cost to be reduced by measuring correlation between gm value and NF value at a low drain current and then performing screening based on the measured gm value for measuring the gm value of a MOSFET using a DC measuring equipment and for performing screening easily. CONSTITUTION:In a MOSFET, carriers flow from a source 22 to a drain 23 via a channel part which is directly below a gate electrode 25 but a noise figure (NF value) of an element is affected by crystal defect or metal contamination at a gate oxide film 24 and a channel interface. When drain current is fully lower than normal operation current, a channel is formed on a surface. Therefore, scattering of the carriers due to crystal defect or heavy metal contamination at the interface can be understood if the gm value is measured at this time. The gm value and NF value at the low drain current are strongly correlated and the NF value can be obtained and screening can be executed simply by measuring the gm value without directly measuring the NF.

Title: Differential transformer
Inventor: IMAIZUMI HIROSHI
IPC: H01F29/10
Filed: 1982-12-14
Abstract: PURPOSE:To take out a differential voltage having excellent linearity, by simultaneously changing voltages, which are induced in two secondary coils. CONSTITUTION:A constant AC voltage is applied to primary coils 23 and 24, respectively so as to excite the coils. Then induced voltages are generated in secondary coils 25 and 26, respectively. The secondary coils 25 and 26 are connected in the reverse direction to each other. Therefore, a differential voltage is yielded across terminals (a) and (b). The voltages induced in the secondary coils 25 and 26 are simultaneusly changed in response to the rotation of a magnetic disk 1. A voltage E1 and a voltage E2 appear across both terminals of load resistors 17 and 18, respectively, through rectifying and smoothing circuits. The polarities of the voltages E1 and E2 are reverse to each other. An output voltage E0 is obtained by E0=E1-E2. The linearity of change in the output voltage E0 with respect to the amount of change is remarkably improved.

When the counter value of the counter exceeds a predetermined time, the output voltage value of the pressure sensor 11 is read in, and the output voltage value of the pressure sensor 11 is written onto a RAM. Thereafter, when the internal combustion engine 1 is restarted and the output voltage value of the pressure sensor 11 is read in, the leaning value stored in the RAM is read out, and a value obtained by reducing the learning value from the output voltage value of the pressure sensor 11 is regarded as an actual output signal value so as to control a fuel injection valve 2.

Title: Plastic bottle with handle
Inventor: YANAGISAWA TAKEO
IPC: B65D25/28
Filed: 1994-09-13
Abstract: PURPOSE: To assuredly attach a handle to a bottle main body, and prevent the handle from deforming by adding a hard filler at least to a part of the handle which comes into contact with the bottle main body. CONSTITUTION: A plastic bottle 1 with handle is formed in such a manner that a handle 3 which is a separate body is attached to a bottle main body 2 which is obtained by blow molding a polyester resin. For such a plastic bottle 1 with handle, a hard filler is added at least in areas of respective fastening parts 32a, 33a of the handle 3, which come into contact with the bottle main body 2. As the hard filler, inorganic particles such as talc, mica, etc., or glass fiber, etc., can be applied, and 5-30wt.% is preferable as the adding quantity. By this method, when the bottle main body 2 is flow-molded, and the handle 3 is attached, a wall surface grows while sliding on an uneven surface which is formed by the hard filler, and a rupture of the bottle main body 2 due to an overdrawing of the wall surface and a deformation of the handle 3 can be prevented from generating. In addition, since a rigidity is increased also, the handle can be prevented from deforming.

Title: Feeding drive cam
Inventor: SASAKI HIDEMI
IPC: F16H53/02
Filed: 1985-10-03
Abstract: PURPOSE:To improve the manufacturing performance, productivity and accuracy of a cam by fixing a reinforcing plate nearly similar to a cam plate and having a smaller diameter than that of the cam plate to both faces of the thin cam plate with a prescribed shape respectively. CONSTITUTION:It is required to form the cam 53 for the shape with high accuracy to attain highly accurate feed drive. In order to form a cam plate 153 specifying the shape of the cam 53 into a thin plate, the plate is manufactured with high accuracy by discharge processing, laser processing or etching processing. Then the reinforcing plates 154, 155 having a slightly smaller diameter than that of the cam plate 163 and formed nearly similarly clip the cam plate 153 from both the faces. Thus, although the circumferential ridge of the cam plate 153 pressed into contact onto a cam follower 45 is provided with sufficient rigidity to attain a prescribed feeding drive while being pressed into contact with the cam follower 45 regardless of the thin plate. Thus, the productivity and accuracy are improved in this way.
