Patent JP-S61284930-A (JP)
Title: Semiconductor device
Inventor: TOMITA YUKIO
IPC: H01L21/318
Filed: 1985-06-11
Abstract: PURPOSE:To prevent a resin-sealed semiconductor device from deteriorating in its reliability due to the resin stress of the device by forming a nitride film as a surface protective film only on the outer periphery of the device. CONSTITUTION:A nitride film 16 is formed as a surface protective film only on the outer periphery of a semiconductor device. For example, a semiconductor layer 12 having an active region 13 formed with a semiconductor element is formed on a silicon semiconductor substrate 11, aluminum wirings 14 are formed on the region 13, and coated with an oxide film 15 as a surface protective film. A nitride film 15 is formed as a surface protective film on the outer periphery of the region 13. Thus, the damage of the protective film due to a resin stress is larger at the outer periphery, the stress is prevented by providing a nitride film having strong mechanical strength, the corrosion of aluminum electrodes is prevented particularly in wet resistance to improve the reliability without altering the structure for forming the nitride film on the entire surface.

Title: Atf signal recorder
Inventor: TAKI TETSUYA
IPC: G11B15/467
Filed: 1986-05-31
Abstract: PURPOSE:To prevent the tracking error by setting the level of a signal current recorded by duplicated writing to a prescribed value under the decision of a level of a preceding pilot signal, thereby suppressing the rocking of a tape at the tracking to a permissible value. CONSTITUTION:A recording/reproducing head 2 is traced along a track recorded on a magnetic tape 3 of a recorder and a pilot signal from an ATF signal recording section of the preceding and succeeding tracks adjacent to both sides of the track by the 1st and 2nd sample and hold circuits 25, 27. The 3rd sampling pulse SP3 is inputted to the circuits 25, 27 and the pilot signal P is held by the 3rd sample and hold circuit 30. Then the output of the circuit 20 is fed to a level discrimination circuit 31 to discriminate whether the level is smaller or larger than the existing signal, and when the signal P is larger, the amplification factor of an amplifier 9 connected to a head 2 is controlled by a storage current setting section 32 to prevent the production of a tracking error.

Title: Bipolar transistor
Inventor: KONO YASUHIKO
IPC: H04N3/16
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To reduce loss at the time of switching of a bipolar transistor, by making the thickness and the impurity concentration of a drift layer satisfy a specified relation. SOLUTION: By making the thickness td and the impurity concentration Nd of a drift layer 201 in a semiconductor device satisfy a relation of 2.1×10<-16> (cm<-2> )<=td/Nd<=9×10<-16> (cm<-2> ), a tail current can be restrained without decreasing the current amplification factor hFE. When td/Nd<=2.1×10<-16> (cm<-2> ), the performance is sharply decreased because a carrier stored in a drift layer 201 at the time of turn-off is discharged outside a device along a flow line shown by an arrow mark Ih. As a result, a junction is biased in the forward direction by a parasitic resistance Rp in a base, and causes the tail current. When 9×10<-16> (cm<-2> )<=td/Nd, the performance is sharply decreased because the current amplification factor hFE decreases. Thereby the tail current can be decreased without deteriorating the current amplification factor hFE.

Title: Rolling mill
Inventor: MASUI TAKESHI
IPC: B21B13/22
Filed: 1983-07-11
Abstract: PURPOSE:To obtain a rolling mill capable of finishing a thin steel billet, having 20-50mm. thickness and manufactured by a continuous casting method, into a hot rolled steel sheet at a low intial investment, by further reducing the thickness of a material, rolled by horizontal rolls with the aid of a die provided to the outlet side of a roll gap. CONSTITUTION:A rolling material 11 of thin cast billet is pushed into a four high mill 13 by applying a compressive force to it from its rear side while rolling it by a push-in rolling mill 14, to roll it between the work rolls W1, W2 of the mill 13. The material 11 is further extruded by a fixed die 2 at the same time, to reduce the material thickness into a prescribed one. The application of the compressive force from rear side by the mill 14 is not required when only the push-in force of mill 13 is enough for the extrusion. Further, the material 11 can be rolled and extruded to the limit of producing a buckling between the rolls W1, W2 and the die 2, by setting the die 2 at the downstream of the outlet of roll gap. Accordingly, the material 11 is perfectly prevented from being forced out between the rolls W1, W2 and the die 2.

Title: Jabber detecting circuit
Inventor: HASEGAWA YOSHIO
IPC: H04L69/40
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To reduce the external size of the circuit by measuring the time when a jabber is detected and the time when the jabber is reset by one capacitor. SOLUTION: When the power source is turned on, the capacitor C2 is not charged, so an output OUT3 is at low level, an output OUT4 is at high level, and a jabber detection signal JAB is at low level. When a transmission acknowledgement signal TxE goes up to high level, a signal TxE.JAB- goes up to high level and a switch SW5 is closed. The time t3 from when the transmission acknowledgement signal TxE goes up to the high level to when the jabber detection signal JAB goes up to the high level depends upon the electrostatic capacity of the capacitor C3 , and the current value and reference voltage VTH of a current source I3 . When a transmission state lasts for longer than the time t3 , the time measurement for detecting the jabber and resetting it for a specific time is performed by the capacitor C, so that the external shape of the circuit can be made small.

Abstract: PROBLEM TO BE SOLVED: To produce a three-dimensional article having an undistorted three- dimensional shape and having a cavity part provided therein without requiring skilled technique. SOLUTION: A mold balloon 20 is expanded into a shape almost same to that on a headrest side. Next, a lower press member 24 is pressed to a first sheet material 16 from below while an upper press member 26 is pressed to a second sheet material 18 from above.

Abstract: PURPOSE:To perform position control in a short time by controlling the position of a magnetic head by the output signal of a quadripartite optical detector which receives reflected light from the magnetic head provided with light reflectance in accordance with the flux density of a vertical magnetic field by a reflection part. CONSTITUTION:A laser beam 17 reflected on the light reflection part of the magnetic head 10 is made incident on the quadripartite optical detector 3 of an optical head. The reflection part of the head 10 is set at the light reflectance in accordance with the flux density of a generated vertical magnetic field, therefore, the relative position of a light irradiation part with the vertical magnetic field maximum part of the head 10 coincides with each other when the intensity of all the light inputted to the detector 3 are set equally when the head 10 is moved. To move the head 10, the position of the head 10 is controlled by feeding back the output signal of the detector 3 to travel devices 6, 7, and the head 10 is fixed at the optimum position. Thereby, it is possible to adjust the position of the magnetic head in a short time.

Abstract: PURPOSE:To shorten the executing time of both call and return instructions by storing temporarily the contents of a program counter to be stored in an instruction mode causing the branch into a high-speed stack buffer. CONSTITUTION:The present contents of a program counter 3 are set to a stack buffer 52 via a multiplexer 51 when a call instruction is fetched and the decoding of an instruction is through. Then the contents of the counter 3 are stored in a subroutine stack 6 via a driver 7 and a stack bus (a). Thus the contents of the counter 3 can be changed to a call destination address before the storing operation to the stack 6 is through since they are once stored in the buffer 52. Thus the next instruction can be fetched early.
