Title: Formation of wiring for semiconductor device
Inventor: HARADA YUSUKE
IPC: H01L21/3205
Filed: 1987-11-10
Abstract: PURPOSE:To prevent a hillock from being generated on the surface of a wiring and to easily remove a side hillock by a method wherein, after a wiring composed of Al or an Al-based wiring has been formed on a semiconductor substrate and this assembly has been heat-treated, the hillock generated on the side of the wiring is etched and removed by making use of a cap film as a mask. CONSTITUTION:A side hillock 25 due to release of a stress inside an Al-Si-based alloy film is generated on the side of a first-layer wiring 23 by a first sintering operation. Then, an etching operation is executed again by making use of a tungsten cap film 24 as a mask. Then, only the side hillock 25 generated on the side of the first-layer wiring 23 is etched; the first-layer wiring 23 returns to a structure having no side hillock. Then, a PSG film as an interlayer insulating film 26 is formed on the whole surface. After that, the interlayer insulating film 26 is flattened. After that, an Al-Si-based alloy film is formed on the flat interlayer insulating film 26 by a sputtering operation. This Al-Si-based alloy film is patterned by photolithographic etching.

Title: Fm modulator for tv
Inventor: TSUBOIKE MITSUYOSHI
IPC: H04N5/40
Filed: 1990-10-19
Abstract: PURPOSE:To reduce a transcation noise even in the case that the APL of a TV signal is low by supplying difference voltage to the AFC control voltage terminal of an FM modulator. CONSTITUTION:The TV signal supplied from an input terminal 11 is outputted after being converted into an FM modulated wave by the FM modulator 1, and from the branch signal of this output, voltage to make the FM modulated wave proportional to an FM spectrum is outputted by a frequency detector 2, and on the other hand, from a part of the inputted TV signal, the mean voltage of the TV signal is detected by a detector 4. Here, a voltage comparator 3 compares the output voltages of the detector 2 and the detector 4, and feeds back this error voltage to the AFC (mean value type automatic frequency control) control voltage terminal of the modulator 1. Accordingly, since in the case that the FM modulated wave is of positive modulation, and the APL (average picture level) of the TV signal is low, the frequency of the FM modulated wave is controlled so as to become low by the error voltage, the almost whole spectrum of the FM modulated wave passes through a receiving side filter. Thus, even in the case that the APL of the TV signal is low, the transcation noise is reduced.

Title: Solenoid assembly and method of extending wear lifetime of solenoid assembly
Inventor: DANIERU ERU KAATAA
IPC: H01F7/127
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To prolong the life. SOLUTION: Part of a solenoid housing 50 to be inserted in a mounting plate has two flat faces 60 continued to mutually opposed two protrudent faces 56. The housing 50 is cut so as to form this double-D structure, allowing the housing to be rotated 180 deg. from one lock position to another. While a plunger is engaged in a vertical motion of the solenoid assembly, this 180 deg. rotation allows the solenoid plunger to contact its unused and unworn surface with a rotary mechanism e.g. actuator, thereby prolonging the solenoid.

Title: Spread spectrum receiver
Inventor: KURIHARA TAKAO
IPC: H04B1/707
Filed: 1987-11-11
Abstract: PURPOSE:To make the operation of initial synchronization at high speed by using a specific pattern so as to obtain the start timing of the initial synchronization and demodulation data. CONSTITUTION:A prescribed pattern for the initial synchronization is included in a sent data and a correction pulse outputted from a binarization circuit 2 through the coincidence between a received PN code and a reference PN code is given to a matching filter 3. When the correlation pulse is coincident with a prescribed pattern, the filter 3 outputs the pulse to an up-down counter 4. Thus, the counter 4 is switched into down-count in the timing (up count by an offset from an external circuit) and outputs a borrow pulse to a PN code phase control pulse generating circuit 8 in case of 0. Thus, the generation circuit 8 is triggered to output a phase control pulse to a reference PN code generator 5 and a phase locked loop circuit 7.

Patent JP-H10108961-A (JP)
Title: Game machine
Inventor: FUKUSHIMA SEIICHIRO
IPC: A63F7/02
Filed: 1996-10-05
Abstract: PROBLEM TO BE SOLVED: To remedy a malfunction that makes the treatment of a special big prize occurring in a special game condition difficult to understand, is apt to cause complaints about the treatment and complicates control. SOLUTION: When a previous big prize occurred, the value of a counter is incremented in a step S118 only when a special big prize occurs, but it is returned to αzeroβ except when it is not a special big prize, so if the value of the counter is judged at a step S104 when there is a win into a start opening, the condition of high probability that makes a big prize occur easily, is only for when the previous big prize was a special big prize. In addition, the cumulative frequency of occurrence of a big prize on the basis of such high probability can be restricted only by the counter, so settings for the game can be made simple and interesting, entertaining properties are followed, and control also can be made simple.

Title: Microwave band frequency synthesizer
Inventor: MISAIZU KIMIHIDE
IPC: H04B1/04
Filed: 1985-12-16
Abstract: PURPOSE:To reduce the degradation in phase noise to reduce the noise by constituting another phase synchronizing loop using the signal from a variable frequency loop as the reference and adopting higher phase comparison there. CONSTITUTION:In the first phase synthesizing loop, a voltage controlled quartz oscillator 10 is stabilized by a reference quartz oscillator 11. A highly stable oscillator of 10MHz which is put in a thermostat and has the temperature controlled is used as the reference quartz oscillator 11. Since the phase noise of the voltage controlled quartz oscillator 10 for a high detuning frequency from a carrier is smaller than that of the oscillator 11 through the stability of the oscillator 10 is lower than that of the oscillator 11, the range of the detuning frequency contributing to the phase noise of the loop output is divided by two oscillators if a natural frequency of the first synchronizing loop is selected, and a low-noise and highly stable reference signal is generated.

Filed: 1999-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a reflectivity control type end face light emitting semiconductor element having a high wavelength detuning quantity at a light absorptive region from a light emission wavelength. SOLUTION: An Nd: YAG layer, e.g. irradiates an n-InP substrate 3 at an optical power of 12 W/cm-2 for about 30 min to cause crystals to be amorphous at the hetero-interface of a quantum well layer 13 due to the heat anneal effect, the condition of the crystals being amorphous changes the quantum level of this well layer 13 to shift the PL peak wavelength to a short wavelength, resulting in that the PL peak wavelength at the beam center is approximately 1290 nm and the PL peak wavelength at a light absorptive region B apart from the beam center by 1 mm is approximately 1460 nm. Thus, the wavelength detuning quantity at the light absorptive region B from the emission wavelength is approximately 170 nm.

Filed: 1990-10-23
Abstract: PURPOSE:To decrease remarkably amt. of a resin and time needed for changing in material and color by making a gap between the inner wall face of a heating cylinder and the heating cylinder and the outer peripheral face of a screw head very small when the screw head is forwarded to its limit and providing a path for a molten resin engraved on the outer peripheral face part of the screw head. CONSTITUTION:When injection is finished, a screw 4 is forwarded to its limit and thereafter, when rotation of the screw is started, a screw head 5 is also rotated and an old resin adhered and remaining in a gap part between an inner wall face 18 and a screw head 5 is peeled off by means of rotation of the screw head 5 when a new resin which is sent from a screw 4 side through a communicating path 12 of a shut-off ring 10 and a molten resin path 14 passes through the gap part and is dispersed into a new resin for changing in material and color. As a distance between the inner wall face 18 of the heating cylinder head and the outer peripheral face part 17 of the screw head is extremely small, the amt. of the old resin adhered on the inner wall face 18 of the heating cylinder head becomes small and the amt. of the old resin dispersed in the new resin is accordingly small.
