Patent JP-S5917846-A (JP)
Title: Manufacture of rotor yoke
Inventor: MIZUYAMA AKINORI
IPC: H02K1/24
Filed: 1982-07-20
Abstract: PURPOSE:To shorten a machining time for yokes by a method wherein an engagement portion of opening and circular hole for a dove-tail groove is fusion- cut in each of medium-thickness steel plates, while these steel plates are laminated, and a fixing key abutment portion is cut to form a hammer-like dove- tail groove. CONSTITUTION:A dove-tail groove 10 for magnetic pole used for engageably fixing each of magnetic poles through a fixing key is formed as follows, the magnetic pole having a leg part in the hammer-like dove-tail form. First, an engagement portion of opening 3 and circular hole 4 of the dove-tail groove is fusion-cut in each of medium-thickness steel plates 1, and these medium-thickness steel plates 1 are laminated into the block form having a desired thickness. Subsequently, a fixing key abutment portion 5 of the dove-tail groove is formed by cutting. By so doing, since the engagement portion of the dove-tail groove is of a circular hole which has a diameter larger than a groove width L, the cutting work is facilitated because the escape space for a cutter is formed when cutting the fixing key abutment portion.

Title: Sound level detecting circuit
Inventor: FUJII KENSAKU
IPC: G10L25/21
Filed: 1989-05-18
Abstract: PURPOSE:To stabilize a detection level by comparing the level of an input signal held in a shift register with the level of a current input signal and using the output of the shift register as a detection level when the level of the current input signal is larger. CONSTITUTION:The shift register is stored with as many as N signal levels samples which are sampled in, for example, 30ms or N/2 signal levels when alternate sampled signals are sampled out. Then, a comparator 2 compares the level of the input signal with the stored signal levels and stores a larger level to update the contents, the level is shifted toward the most significant address (rightward), and the level of the signal in the most significant address is outputted as the sound detection level. Consequently, the level never varies to a no-sound level in a sound section and the no-sound level can be varied to a no-sound level at the end of the sound section with small delay of 30ms.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device which can reduce the parasitic capacitance between wiring formed on a semiconductor substrate and a capacitor, formed on a passivation film formed an the wiring and a method for manufacturing the device. SOLUTION: A passivation film 15 is formed on a semiconductor substrate 11 on which a semiconductor element and wiring 13 and 14 are formed and a capacitor 19 is formed on the passivation film 15 by successively forming a lower electrode 16, a capacitor insulating film 17, and an upper electrode 18 on the film 15. Immediately below the lower electrode 16, a plurality of air gaps (cavities) 23 consisting of recessed grooves 31 formed into the passivation film 15 are arranged at required intervals.

IPC: C21D9/30
Filed: 1990-05-17
Abstract: PURPOSE: To enhance the durability of a crank shaft in a range of a migration radius from a crank piston to a crank arm by subjecting the migration radius to a hardening treatment of a prescribed depth and working the surface up to the end of a contact collar to a prescribed roughness with the cutting edge between a supporting point and the migration radius as a start point.

The heating of this case is usually inductively executed and is cooled with water for the purpose of rapid cooling. The surface up to the end of the contact collar 3 is worked at the roughness 'RZ' larger than 6.3 μm with the cutting edge 6 between the supporting point 1a and the migration radius 4 as the start point. As a result, the durability of the crank shaft in the migration part described above is enhanced without changing geometry and without executing wasteful surface working.

Abstract: PURPOSE:In a spiral electrode structure where the positive and the negative plate strips are wound through a separator, to reduce the defective process when constructing the cell by cutting the end corner section of a current collector exposed at the end-of-winding portion of one plane such as the positive plate located at the outermost circumferential section and providing the tapered shape. CONSTITUTION:The positive plate 3 is laminated through a separator 5 with the negative plate 4 then the entirety is wound spirally to form a spiral electrode member 9 where the positive plate 3 is located at the outermost circumferential section. The titanium net current collector 6 exposed at the end-of-winding portion of the positive plate 3 is tapered to prevent the shifting or the jutting out when inserting the electrode member 9 into the positive inner can 11. The shifting due to the stopping of the exposed current collector 6 at the open circumferential section 11' of the inner can 11 is slight, thereby it will be inserted into the inner can 11 without jutting from the inner can.
