Title: Manufacture for diaphragm for speaker
Inventor: OKUMURA MASATOMI
IPC: H04R7/02
Filed: 1988-05-06
Abstract: PURPOSE:To obtain a diaphragm having excellent specific modulus by forming a membrane by melt spraying a diaphragm material composed of ceramics, metal, or the mixture of them, which is made into melt spraying powder, on a die having the shape of the diaphragm and accumulating the material and further executing high temperature hydrostatic pressure pressing (HIP hereafter) processing for the formed membrane. CONSTITUTION:For the diaphragm for a speaker, first the membrane having the shape of the diaphragm is manufactured by using a plasma melt spraying device 1. The melt spraying device 1 has an electrode 1a and a nozzle 1b and introduces a gas obtained by mixing the appropriate quantity of hydrogen gas in either a nitrogen gas or an argon gas into a clearance 1c between the electrode 1a and the nozzle 1b. Further, the mixed gas is ionized and made into a plasma flame 1d by applying electric power from a power source connected to a terminal to the clearance 1c between the electrode 1a and the nozzle 1b. A membrane 5 formed by the plasma melt spraying is set to an appropriate jig 10, placed in a high pressure container 6 of a HIP device which can also work as a kiln, and heated by a heater 8 composed of graphite, and the argon gas is introduced from a gas supply port 9 at a point where the temperature of the membrane 5 reaches approximately 500 deg.C.

Title: Image forming device
Inventor: FUKUSHI YUKIHIRO
IPC: B65H43/04
Filed: 1984-05-30
Abstract: PURPOSE:To prevent misoperation by counting a signal generated by a sorter every time a form is stored normally, and correcting the frequency of image formation into a counted value when abnormality occurs in the sorter. CONSTITUTION:A sorter control part 56 turns on a signal C-RCV for a certain time with a signal from a paper detection switch 34. A copying machine control part 51 counts how many times the signal C-RCV is turned on (the number of forms stored normally in the sorter) separately from the quantity of copies, and stores the counted value. If a jam is caused in the sorter, the copying machine carries on copying operation until the jam id detected, so there is a difference generated between the number of forms P sorted by the sorter and the number of forms P copied by the copying machine. For the purpose, the copying machine control part 51 replaces the stored frequency of on-level transition of the signal C-RCV with the number of copies counted so far when release the sorter from the jam. Consequently, there is no difference between the number of forms stored in the sorter and the number of copies taken by the copying machine when the copying operation is restarted.

Patent JP-S5734366-A (JP)
Title: Thyristor
Inventor: TAKEDA MITSUYOSHI
IPC: H01L29/10
Filed: 1980-08-09
Abstract: PURPOSE:To improve the gate sensitivity of the subject thyristor without reducing dV/dt resistant strength by a method wherein, in the case of a three-terminal element having four-layer structure, an n layer (or a p layer) is provided, aparting from an emitter layer, on the p base layer (or an n base layer) on which a gate electrode will be provided. CONSTITUTION:For example, in the case of a four-layer thyristor consisting of a pE layer, an nB layer, a pB layer and an nE layer, an nO layer 5 is formed in the pB layer 2 simultaneously with the diffusion performed on the nE layer 4, for example, and the nO layer and the pB layer are short-circuited by an electrode G. In this structure, when the gate voltage having the gate G as positive and a cathode as negative is applied, a junction 13 is biased inversely and the gate current reaches the nE layer 4 through the route as shown by solid arrow lines, thereby enabling to increase the implanting efficiency and increase the gate sensitivity. On the other hand, the dV/dt resistant strength is not reduced even when the nO layer is provided, because the direction of the displacement current ingredient shown by the dotted lines has no relation with the existence of the nO layer 5. Accordingly, a thyristor which is suited to a high-sensitive and low current capacity element having a low gate trigger current can be obtained.

Title: Manufacture of solder bump
Inventor: INOUE NAOAKI
IPC: H01L21/60
Filed: 1988-05-06
Abstract: PURPOSE:To perform a manufacturing process in the air by carrying out electric solder plating with a glass film as a mask in such a state that an Au thin film remains as an antioxidizing film at the solder bump formation part of a barrier metal layer. CONSTITUTION:After removing an Au thin film 4c with the exception of a solder bump formation part, a glass film is formed. Accordingly, a part covered with a mask results in the absence of the Au thin film 4c in the case of electric solder plating and then, no reaction of Au to glass takes place at the above part. This approach makes it possible to obtain a superior glass film 5 which sufficiently fulfils its function as the mask. Further, the Au thin film 4c remains as an antioxidizing film at the solder bump formation part of a barrier metal layer 4. Thus, electric solder plating is performed in the air.
