Patent JP-H0535264-A (JP)
Title: Manufacture of music box and diaphragm
Inventor: ISAKA AKIHIKO
IPC: G10F1/06
Filed: 1991-07-26
Abstract: PURPOSE:To shorten the time for as much as possible and to cause no decrease in sound quality due to the tuning by the side slanting length or valve width and valve tip width of a vibrating valve different according to music and tuning the valve by grinding. CONSTITUTION:The tapered side of the vibrating valve is varied. By this method, the frequency is low when the length (x) of the slanting surface is short and high when long. The vibration plate is constituted by using the vibrating varied in the elements corresponding to music and this plate can be incorporated in the music box. The valve width (b), valve tip with (v), slanting surface length, (x) valve length L, etc., as those frequency decision elements relate to the shape viewed in a plan, wire cut work by a electric discharge machine is relatively easy according to the free design of the valve shape. Thus, once the plate in the desired shape is cut by the machine, only sight tuning is required thereafter and there is no vibration in the value thickness, so a decrease in the sound quality is never caused.

Title: Bit-correspondence processing system of flip-flop group
Inventor: SETO HAJIME
IPC: G06F13/24
Filed: 1980-12-29
Abstract: PURPOSE:To achieve correspondence processing by fractionizing the state of peripheral equipment by previously specifying the group number of a flip-flop and a bit position in it, and then generating an interruption signal to a CPU only when the state of the equipment is coincident. CONSTITUTION:A specifying register IDR is stored with a flip-flop group number and information on the specification of a bit position in the same group. A setting specifying part ST inputs the input information to a specification information terminal IDT and when a register-storage command terminal RST is specified, this input information is stored in the register IDR. With a set key STB pressed, the circuit of a condition discriminating part CDD starts to compare the states of flip-flops, which correspond to devices, from a terminal FFGm with the contents of the register IDR. Then when a flip-flop group bit coincident with the specified contents of the register IDR turns on, the output CCS of the discrimination part CDD is used as the interruption signal to the CPU, which is then stopped.

Patent JP-S5891147-A (JP)
Title: Molding of silicon nitride and its production
Inventor: SATAKE TOSHIAKI
IPC: C22C29/16
Filed: 1981-11-26
Abstract: PURPOSE:To obtain moldings having excellent dimensional accuracy, good surface roughness and specific rates of nitriding in moldings of Si3N4 sintered after reaction by specifying the rate of packing of Si in the molding stage, the initial reaction temp. with the N2 of the moldings and the heating rate and temp. thereafter. CONSTITUTION:This molding is a molding of Si3N4 contg. metallic Si wherein 20-80% of metallic Si is converted to Si3N4. In order to obtain the same, fine powder of Si is so packed as to contain >=64vol% of the molding and is molded to the molding. If the ratio is <64%, the dimensional accuracy is not kept and deformation arises in the heating stage of removing the binder. The molding is sintered after the removal of the binder and at this time the molding is brought into contact with N2 at 1,000-1,100 deg.C to convert the surface of Si particles to Si3N4 to prevent the sintering of the Si particles, whereby high dimensional accuracy is obtained. Further the molding is heated to intensify strength, wherein the molding is heated to 1,200-1,380 deg.C at <=20 deg.C/hr heating rate under repetition of contact with N2 or holding in a vacuum and introducing of N2.  When the heating rate exceeds the above-mentioned limit, surface smoothness is lost by spheroidal deposition of Si. Within the above-described temp. range, the rate of conversion to Si3N4 is maintained at necessary and sufficient rate, i.e. 20-80%.

Title: Testing method of receptacle-type optical module
Inventor: SHIGENO KAZUO
IPC: G01M11/00
Filed: 1990-07-17
Abstract: PURPOSE:To improve the precision in evaluation of the reliability of a module to be measured, by prescribing a characteristic fluctuation value of the module by the square mean of characteristic fluctuation values in three optical connectors. CONSTITUTION:In regard to four cases when displacement is made by 1 mum in the direction of +x between optical connectors C and B, in the direction of +y between C and B and in the direction of +y in the center of optical connectors A, B and C, fluctuations in the optical connectors A, B and C and square mean values of these three connectors for measurement in a set are rearranged. According to this rearrangement, it is known that values of little nonuniformity are obtained for various displacements by 1 mum by taking the square mean of fluctuation values by using the set of the optical connectors having a core at the position of an equilateral triangle of high symmetry. Accordingly, it is possible to reduce the nonuniformity in the fluctuation value of a coupling characterstic and to increase the precision in evaluation of reliabil ity.
