IPC: H01L21/306
Filed: 1990-03-07
Abstract: PURPOSE:To enable a gentle taper-shaped contact hole to be formed without any protruding part by succeeding anisotropic etching by cladding an additional insulation film to an insulation film which is formed at a recessed part. CONSTITUTION:A first-layer aluminum wire 11 is formed on a semiconductor substrate, then an insulation film 12 which consists of SiO2 is formed, and a photo resist 13 as a mask for etching is clad on the insulation film 12. Then, an opening H is formed selectively on the photo resist for exposing the insulation film 12 and the exposed insulation film 12 is etched by anisotropic etching, thus forming a recessed part. Then, after eliminating the photo resist 13, for example SiO2 is deposited on an entire surface, thus forming an additional insulation film 14. After that, by performing anisotropic etching to the additional insulation film 14, the additional insulation film 14 remains in projecting shape at a side wall of the recessed part. When anisotropic etching continues until a first-layer aluminum wire is exposed, a gentle tape-shaped contact hole without any projecting part can be formed.

Filed: 1987-03-11
Abstract: PURPOSE:To obtain a high sensitivity sensor, by forming diffused resistors in the vicinity of a weight part and in the vicinity of a frame part so that the longitudinal directions of the resistors are aligned with the extending direction of deflecting parts. CONSTITUTION:Diffused resistors R1, R2, R3 and R4 are arranged so that the longitudinal directions of the resistors are in parallel with the extending directions of corresponding deflecting parts 11-1-11-4. The resistors are bent at the central parts in order to obtain large effective lengths in this structure. The width of each of the deflecting parts 11-1-11-4 is not restricted by the length of the longitudinal direction of each of the diffused resistors R1-R4. As a result, the value of stress T, which is applied on the diffused resistor forming part, is large when a force having the same magnitude is applied on a weight part 12. Therefore a large output signal is obtained.

IPC: G01G23/42
Filed: 1981-04-15
Abstract: PURPOSE:To improve an operating efficiency of a weighing recording, by a method wherein it is automatically detected whether a weighing result is heavier or lighter than a given weight, and if it is heavier, it is recorded in a total item, and if it lighter, it is recorded in a tare item. CONSTITUTION:When a truck stops on a table 3 and the weight is weighed, the weighing result is compared with a given weight being fed to and set at a measuring device. If the given weight is set to, for example, 9,000kg, and if the truck is empty and the dead weight or a tare is 8,200kg, it is detected that the weighing result is lighter than the given weight, and [8,200] is automatically recorded in a [tare] item of a delivery and despatch slip. If a loading weight of gravel is, for example, 9,200kg, a total weight goes to 17,400kg. Then, it is detected that the weighing result is heavier than the given weight, and the weighing result is automatically recorded in a [total weight] of the slip. This eliminates the need for changing-over of a changing-over switch of a measuring device, which results in improving an operating efficiency.

Title: If signal reproduction circuit
Inventor: SAITO AKIRA
IPC: H04B1/04
Filed: 1994-03-28
Abstract: PURPOSE:To easily reproduce an IF signal without provision of a PLL circuit consisting of a frequency divider, a phase comparator and a reference signal oscillator for reproducing the IF signal by mixing an output of a voltage controlled oscillator and an output signal of an FM modulator so as to extract the IF signal. CONSTITUTION:A control output signal of a phase comparator A4 required to make a frequency of a direct FM modulator 2 stable is branched to a VCO 8 to control the VCO 8, from which a local oscillation signal fL is obtained. Then the local oscillation signal fL and a transmission high frequency signal fo are mixed by a mixer 9 and a difference frequency is used for a reproduced IF signal. In this case, the relation of IF=fo-fL is established and a circuit with the same characteristic such as a temperature declination in the oscillating frequency or the like as that of the direct FM modulator 2 is employed for the VCO 8, then the IF reproduction signal frequency is kept substantially constant. Furthermore, the frequency deviation in the reference signal oscillator A5 is cancelled by the mixer 9. As a result, the IF reproduction is implemented by using the VCO 8 and the mixer 9 only and then the circuit is simplified.
