Patent JP-H0479266-A (JP)
Title: Manufacture of semiconductor device
Inventor: FUJISAWA AKIRA
IPC: H01L27/115
Filed: 1990-07-20
Abstract: PURPOSE:To hold a stress caused by crystallization of a ferroelectric thin film to the minimum for fabricating a high-quality capacitive element at a high yield by patterning the thin film which would be a ferroelectric layer before heat treatment is effected on the thin film. CONSTITUTION:A lower electrode 103 is formed with, for example, platinum, by the sputtering method or other method. Then, it is patterned by a photolithography with platinum left over only in the region required for forming a capacitive element. Next, a thin film 201 which would be a ferroelectric layer is formed by, for example, the sputtering method and is so patterned that it may be left over at least in the region required for forming the capacitive element. After that, the thin film 201 which would be a ferroelectric layer is heat-treated for the first time to be crystallized. The thin film 201 which would be a ferroelectric layer is heat-treated after patterning as shown above, therefore a stress to be caused by a pronounced volumetric shrinkage of the thin film which accompanies the crystallization of the thin film is held to the minimum. Consequently, an effect given to the characteristics of a transistor formed under the capacitive element can be minimized and the exfoliation of the ferroelectric thin film itself is also prevented.

Title: Incoming call notifying device
Inventor: HAMADA HIROYUKI
IPC: H04M1/00
Filed: 1990-07-23
Abstract: PURPOSE:To notify incoming calls in various manners by processing a prescribed incoming call signal in such a way that, after the data stored in a RAM are read out and processed and the kind of the incoming call signal contained in the data is discriminated, the prescribed incoming call signal is outputted and an address is set. CONSTITUTION:A control signal received by means of a transmission/ reception circuit 103 is sent to a home bus interface section 104 and subject to protocol conversion by means of a home bus protocol controller. After the protocol conversion, the control signal is sent to the data bus of an MPU 106 and received data are recorded at the data address of a RAM 109 as received data. Thereafter, the MPU 106 reads out the received data in the RAM 109 and discriminates that the data are a line ringing command to a designated address. Then the MPU 106 sends 'line ringing' to an incoming call I/F circuit 114 through a decoder 113. A line ringing signal pattern is sent to an incoming call signal drive circuit 115 from the 'line ringing' information and an incoming call signal notifying means 116 is actuated.

Abstract: PURPOSE:To prepare an inexpensive high-strength conductive copper alloy excellent in strength and springiness and also excellent in corrosion resistance, by applying heat treatment to an alloy having a specific composition consisting of Zn, P, Sn, Al and Cu under proper condition after final cold rolling. CONSTITUTION:An alloy containing, on a wt. basis, 10-40% Zn, 0.005-0.070% P, 0.05-1.0% Sn and 0.05-1.0% Al and comprising the remainder of Cu and inevitable impurities is subjected to final cold rolling and subsequently subjected to heat treatment at 150-700 deg.C for 30sec-20hr to obtain a high-strength conductive copper alloy simultaneously and remarkably enhanced in strength, especially, tensile strength and elongation and a spring limit value. The above mentioned alloying components are limited for such reason that strength is reduced if Zn is below 10% and material properties are not stable if it exceeds 40% and, if P is below 0.005%, strength and corrosion resistance are reduced and, if exceeds 0.070%, conductivity is lowered and grain boundary attack is easy to be generated while strength is lowered if Sn is below 0.05% and processability and conductivity are lowered if exceeds 1.0% and strength is reduced if Al is below 0.05% and processability and conductivity are lowered if exceeds 1.0%.

Abstract: PURPOSE:To detect even variation in torque which varies in one rotation by calculating torque corresponding to the rotational position of a torque transmission shaft by an arithmetic means by synchronizing the detection signal of a detection head with the pulse signal of a position detecting means. CONSTITUTION:While the torque transmission shaft 21 makes one rotation in an unloaded state, a detection signal (s) is by detection coils 28 and 29 and while the torque transmission shaft 21 rotates, 32 pulse signals (p) are outputted by a rotary encoder 31 in one rotation. The signals (s) and (p) in the unloaded state are stored in the memory of a microcomputer 39 by turning on an initial setting switch 43. When the varying torque is applied to the transmission shaft 21, induced magnetic anisotropy is generated in magnetic metallic thin belts 22 and 23 to vary the magnetic permeability in the direction of excitation by exciting coils 26 and 27 and the variation appears at the detection coils 28 and 29, so that a detection signal DELTAs is obtained. The microcomputer 39 reads the value of the detection signal (s) in the unloaded state out of the memory according to the pulse signals (p) from the encoder 31 and compares the value of the detection signal DELTAs to calculate instantaneous torque (t) corresponding to the rotational position of the transmission shaft 21.
