IPC: H01L27/088
Filed: 1985-10-31
Abstract: PURPOSE:To reduce the number of wirings while enabling driving at a TTL level normally used by unifying a high withstanding-voltage field-effect semiconductor device and a logic circuit, such as a shift register, a latch, a gate, etc. CONSTITUTION:An insulator layer 31 is attached to a p-type semiconductor substrate 30, and n-type ions are implanted partially to form an n-type ion implantation layer 41 to the substrate 30. Thick insulating substance layers 33 are shaped through oxidation, and a p-type impurity is ion-implanted or diffused from openings 35, 37 to form p-type impurity layers 42. An n-type impurity is diffused similarly to shape n-type impurity layers 43-1-43-4. Accordingly, a high withstanding-voltage field-effect semiconductor device and a logic circuit are unified and manufactured by using a DSA technique, thus simplifying a manufacturing process, then easily preparing the circuit because the manufacture is performed with the same semiconductor substrate 30.

Title: Power control circuit for sound synthesizing device
Inventor: TATSUTA NORIHIRO
IPC: G10L19/00
Filed: 1992-09-16
Abstract: PURPOSE:To easily understand the content of a document without finishing the document in its midst by supplying power until the sound transformation operation of stored data is finished even when an IC card is unloaded from a main body. CONSTITUTION:If an IC card 2 is detached from the main body while the sound transformation operation is carried out by a sound synthesizing circuit 6, a detective switch 11 is opened, a bias current supplied to the base of a control transistor 13 through a power switch 10, the detective switch 11 and a resistor 15 is cut off and the signal level of a detective signal input terminal 8 is inverted from an H level to an L level. In this case, the sound synthesizing circuit 6 is in an operative state and the output signal of a driving signal output terminal 9 is not inverted from the H level to the L level. Thus, even when the detective switch 11 is opened, a power is conducted to a power supply transistor and held. Then, the reading and sound changing operations of data stored in a data memory circuit 5 are continuously carried out even after the IC card is detached.

Title: Semiconductor laser and manufacture thereof
Inventor: SUDO HISAO
IPC: H01S5/00
Filed: 1984-11-21
Abstract: PURPOSE:To reduce the magnitude of wet current, by reducing the difference in steps between the interface between an active layer and a clad layer and a junction plane, which stops the current. CONSTITUTION:On a substrate 1a, on which grating is formed, a guide layer 2, an active layer 3 and a P type InP layer 4a are formed. A stripe shaped SiO2 insulating film 13 is formed thereon. Then selective etching is performed. By using the substrate 1a as a stopper, the surface remains approximately flat. Then, a P type InGaAsP layer 7 and an N type InP layer 8a are grown, and a block layer 9a is formed. At this time, since the growing of the surface of the insulating film 13 is stopped, general height of the P type InGaAsP layer 7a is made higher than the P type InP layer 4. Even if the height is slightly changed, the height of the P type InGaAsP layer 7a at the side end of the insulating film 13 approximately agrees with the height of the P type InP layer 4a. At the N type InP layer 8a, the height of the side end of the insulating film 13 becomes the same. After the insulating film 13 is removed, a P type InP layer 4b and a contact layer 5a are grown, electrodes 11 and 12 are deposited and a DFB laser can be formed.

Title: Method for preventing crack of cold pilger die
Inventor: NISHIHAMA WATARU
IPC: B21B27/00
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent cracking of a caliber bottom part by nitriding a roll die caliber surface to generate the compressive residual stress in the roll die caliber bottom part. SOLUTION: Iron nitride is generated on the surface part of a roll die to form a hardened layer by nitriding the roll die, the compressive residual stress in a steel member is increased, and the time fatigue strength is sufficiently improved on the high stress side. When cold rolling is performed on a metallic tube stock 5 by nitriding the roll die, the compressive residual stress is generated in a caliber bottom part, the tensile stress to be concentratedly applied to the bottom part during the cold rolling is relaxed by the residual stress, and small cracks are hardly generated in the surface in contact with the metallic tube stock. Even when small cracks are generated, they can be prevented from propagating inside by relaxing the tensile stress propagating in the die by the compressive residual stress.
