Title: Semiconductor device having junction structure of element isolation region of different shape
Inventor: MORITA SHIGERU
IPC: H01L21/76
Filed: 1989-12-27
Abstract: PURPOSE:To restrain crystal defect generated in a semiconductor substrate in the vicinity in contact with a junction point, and improve the junction breakdown strength of an impurity diffusion layer in contact with the junction point, by making the junction point have an obtuse angle between both regions. CONSTITUTION:When a fine buried element region 12 is joined to a LOCOS element isolation region 11 having a wide area in an integrated circuit formed on a semiconductor substrate, the region 11 side end portion of the region 12 is formed so as to be a fan-type taper 13 having a taper angle of, e.g. 20 deg. to one side of the region 12. The taper 13 part of the region 12 is joined to a rectilinear side 11a of a region 11 perpendicular to an axis C of the region 12 so as to be overlapped. As a result, a buried junction is so formed that the angle between the taper 13 of the region 12 and the rectilinear side 11a of the region 11 becomes, e.g. 120 deg.. By making the junction point have an obtuse angle between both regions, crystal defect generated in a semiconductor substrate in the vicinity in contact with the junction point is restrained, and the junction breakdown strength of an impurity diffusion layer in contact with the junction point can be improved.

Title: Roof provided with solar batteries and method for setting solar battery panels
Inventor: MASUDA TOSHIHIRO
IPC: H01L31/042
Filed: 1999-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a roof provided with solar batteries, which is ensured with respect to the waterproofing performance and cooling function thereof, and to provide a method for setting solar battery panels. SOLUTION: This solar battery panels 50 are arranged along declining ridges 13 of the roof 10. One side of each solar battery panel 50 is arranged along the declining ridge 13, and a coping member 13A is set along the declining ridge 13 so as to caver one side. Thus, a joint portion formed between the solar battery panels 50, arranged along both sides of the declining ridge 13, is concealed by the coping member 13A, and therefore the joint portion is not exposed directly to rainwater. Furthermore, since the opening of a gap formed between the solar battery panel 50 and the substrate surface of the roof is blocked with the coping member 13A on the side of the declining ridge 13, infiltration of rainwater into the interior of the opening can be eliminated, thereby ensuring the waterproofing performance of the roof 10.

IPC: H03M1/86
Filed: 1991-11-27
Abstract: PURPOSE:To improve the response without losing the linearity of D/A conversion in a PDM (pulse density modulation) D/A converter circuit by using an error between a D/A conversion detection value and a 50% command so as to correct the original command thereby forming a new correction value. CONSTITUTION:According to a command and a digital command from an error computing element 3, a PDM circuit 4A implements pulse density adjustment to input PDM pulses of a prescribed number to a linear filter 6A. The pulse is inputted to the computing element 3 via an A/D converter 2, in which a digital command value (true value) is calculated and outputted to have a 50% output to the circuit 4A. Simultaneously, an error epsilonr between the 50% command value and a detected value being the output of the converter 2 is calculated and the error epsilonr is inputted to a correction computing element 5. The computing element 5 uses the error epsilonr with respect to a digital command N to be inputted to implement command correction calculation and inputs the result to a PDM circuit 4B, in which pulse density modulation is implemented to generate a PDM pulse and an analog output equivalent to a command ST is given via a linear filter 6B.

Filed: 1989-12-28
Abstract: PURPOSE:To prevent the growth of lumps, produced on the upper part of the inner wall of the body of a furnace, by forming the inner diameter of the furnace body so as to be widened gradually toward the bottom of the furnace body. CONSTITUTION:When the melting of cold material is advanced in a furnace body 71 by the effect of an induction coil 32, lumps are produced on the upper inner wall of the furnace body 71 in accordance with the progress of the melting, however, the inner wall of the furnace body 71 is widened gradually toward the lower part of the same and, therefore, the lumps produced on the upper inner wall are readily dropped. Further, when new cold material is thrown into the furnace body 71 and the cold material pushes the lumps, the lumps are dropped simply. Accordingly, the lumps will never grow or enlarge gradually.

Title: Production of hot dip galvanized steel plate excellent in plating adhesion
Inventor: IWAI MASATOSHI
IPC: C23C2/02
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To produce a hot-dip galvanized steel plate excellent in plating adhesion by applying, prior to plating, heating treatment to the surface of a steel plate under specific conditions, and developing cracking in an oxide film, at the time of applying hot-dip galvanizing to a steel plate on which an oxide film remains. SOLUTION: Before hot-dip galvanizing is applied to a steel plate (e.g. hot rolled steel plate) on which an oxide film remains, a part of the oxide film is reduced by holding for >=20sec in a reducing atmosphere of >=500 deg.C. Subsequently, prior to plating treatment, the surface of the steel plate is heated to >=500 deg.C while regulating the average heating rate between room temp. to 500 deg.C to >=10 deg.C/sec, or the steel plate is heated and the surface of the steel plate is cooled, before immersion into a plating bath, by >=50 deg.C at >=10 deg.C/sec average cooling rate, or the temp. of the surface of the steel plate is regulated so that it is higher by >=50 deg.C than the temp. of the plating bath.  By this method, cracks are developed in the oxide film and plating metal is allowed to penetrate into the oxide film, and the hot-dip galvanized steel plate having superior adhesion of plating can be obtained.

Title: Tire pressure detecting device
Inventor: TAGUCHI TAKEYASU
IPC: G01L17/00
Filed: 1992-12-18
Abstract: PURPOSE:To indirectly detect tire pressure and improve its detecting precision. CONSTITUTION:In a step 171, a maximum peak gain Gp is calculated in a frequency band where the presence of a resonance frequency is estimated. In a step 172, frequencies f1, f2 in the points under the threshold of a predetermined frequency band Fb are calculated with several % (for example, 70%) of the peak gain Gp as a threshold Gs. In a step 173, it is examined whether two points (p) under the threshold are present or not, and only when only two points are present, the procedure is advanced to a step 174, in which the intermediate frequency fm between the calculated frequencies f1, f2 is taken as a resonance frequency (f). On the basis of this resonance frequency, the state of tire pressure is detected.

Title: Self-closing check valve
Inventor: TAKAHASHI AKITAKE
IPC: F16K15/06
Filed: 1990-11-30
Abstract: PURPOSE:To perform the pneumatic conveyance of granules in a stable manner by making a valve element, installed in the downstream side end of a valve stem by dint of spring force, contact with a ringlike projection in a casing, and covering the inside of the casing. CONSTITUTION:When high pressure air is fed to a compressor and it is entered into a check valve 18, a valve stem 20 is moved to the downstream side against the resilient force of a compression spring 24, and a contact projection 33 between packing 27 and a casing 19 is opened, thus this air is fed to the side of a blowdown tank. Since air pressure to be fed to this blowdown tank is almost a constant value in relation to a granule conveying capacity, a spring constant is being preset to open only at a time when it is exceeded the specified value. Subsequently, a specific air quantity of constant pressure is stored in the blowdown tank, and when the compressor stop its operation, pressure in pneumatic pipeline is little lowered, so that extensible force of the spring 24 grows larger than the air pressure, thus an opening is closed before the high pressure air with granules in the blowdown tank flows back.
