Title: Glass valve for cathode-ray tube
Inventor: SUGAWARA TSUNEHIKO
IPC: H01J31/20
Filed: 1995-09-14
Abstract: PURPOSE: To construct a cathode-ray glass bulb with a small wall thickness and light weight by controlling the cooling speed and maintained temp. at the time of slow cooling after glass molding process of the glass bulb. CONSTITUTION: In physical strengthening of the region with the panel 3 of a glass bulb 2, the amount of the compression stress δKC generated at quick cooling from a high temp. near the glass softening point is adjusted with the time required for the glass surface temp. to sink to the strain point from the slow cooling temp. At this time, δKC is made so that the relations 1<CδVTmax /δSG<=1-(KC/δ SG) and δ KC<=-30kg/cm <2> are met, where δSG represents the fracture strength of the glass bulb and δVTmax the max. value of tensile stresses generated when the atmospheric pressure is applied to the surface of the glass bulb which is evacuated, under the condition that 2<=C<=4. Thereby the glass bulb can be constructed with small wall thickness and light weight without implosion.

Title: Two-stage pulsed arc welding
Inventor: SUZUKI HIROSHI
IPC: B23K9/09
Filed: 1984-11-09
Abstract: PURPOSE:To prevent generation of spatter surely, make droplets small particles and speed up welding by impressing the second pulse current before the first pulse current rises up and making the pulse current off by one pulse at the time of short circuit. CONSTITUTION:Before the first pulse current IP1 rises up, the second pulse current IP2 of larger peak is impressed. When welding is made by short arc length, droplets are separated by pinching force caused by the peak current IP2 by the high frequency pulse current before the wire short-circuits to the base metal to prevent generation of spatter. When short circuit is caused by the first pulse current IP1, the first and second pulse current IP1 and IP2 become off, and shift to base current IB. Thus, generation of spatter is prevented surely.

Title: Acoustic boundary wave device and its production
Inventor: MISHIMA NAOYUKI
IPC: H03H9/10
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To produce a compact and inexpensive device which has a function equivalent to an SAW (surface acoustic wave) device by transmitting an SAW along the boundary surface between a 1st layer of an Si group and a piezoelectric 2nd layer. SOLUTION: A dielectric film 4 having the comb-line grooves 3 is formed on the main side of a 1st substrate 2 of an Si group, and these grooves 3 are filled with a conductive material to form a comb-line electrode 5. Then a piezoelectric 2nd substrate 6 is bonded on the substrate 2. Thus, an acoustic boundary wave device is obtained. It's desirable for the substrate 2 to have high resistance of 10Ωcm or more to prevent the DC leakage caused by the electrode 5. The substrate 6 uses LiNO3 ., for example. The area of the main side of the substrate 6 is smaller than that of the main side of the substrate 2, and the substrate 6 has only an effective area that is necessary at least for transmission of the acoustic boundary wave. The film 4 uses SiO2 , for example.  In such a constitution, an SiO2 film is formed just by applying an oxidation treatment on the main side of the substrate 2.

Title: Ofdm synchronization demodulation circuit
Inventor: SATO MAKOTO
IPC: H04L27/227
Filed: 1994-09-30
Abstract: PURPOSE: To provide accurate frame synchronization and symbol synchronization. CONSTITUTION: I and Q signals from A/D converters 18 and 20 are supplied to an envelope detection circuit 31 and an envelope is detected. A movement average circuit 32 obtains the movement average of the envelope and a minimum value level detection circuit 34 detects the minimum value level of movement average output. A comparison level generation part 37 sets a comparison level higher than the minimum value level for a prescribed value and a level comparison part 38 detects a timing when the movement average output exceeds the comparison level. The timing when the movement average output rises from the minimum value level is matched with the end timing of a null symbol period at all times regardless of the influence of multipath and the C/N of reception signals.  By attaining synchronization based on the timing detected by the comparison part 38, the accurate symbol synchronization and frame synchronization are obtained.

IPC: H01L27/146
Filed: 1994-10-03
Abstract: PURPOSE: To form an image of high quality over the entire pixel constituent element region of a solid state image sensor even when the exit pupil of an imaging lens system is near by disposing the optical axis of a microlens at the positional relation suitably displaced to the optical axis side of the system with respect to the central axis of a pixel opening. CONSTITUTION: The positional relation of a pixel opening 14 and a microlens 20 of a pixel constituent element 12 is set to the positional relation in which the optical axis A2 of the microlens 20 is displaced to the optical axis A0 side of an imaging lens system with respect to the central axis A1 of the opening 14 by a displacement δh responsive to a center distance (h) between the axis A0 of the system and the axis A1 of the opening 14. Then, even when the exit pupil of the system is near, the luminous flux fetched by the lens 20 is efficiently fetched to the opening 14 despite the position of the element 12 on a solid state image sensor 16. Accordingly, the image of high quality can be formed over the entire region of the element 16.

Abstract: PURPOSE:To reduce the size of a device provided with a one-way clutch by a method wherein a rotary member is extended in the direction of an axis, and a space on which the large part of an idle wear fronts is formed between a reduction gear and a clutch body. CONSTITUTION:A reduction gear 31 generated with a small part 19a of an idle gear 19 is integrally mounted to the tip part of a rotary member 24.

The rotary body 24 is extended in the direction of an axis, and an annular space G on which a large part 19b of the idle gear 19 fronts is formed between the clutch body 22 and the reduction gear 31. Thus, separation of a drive gear 33, engaged with the large part 19b of the idle gear 19, axially away from the clutch body 22 is suppressed. Besides, since there is no need to increase the size of the reduction gear 31, a starting device 16 is not extended in a direction extending at right angles with the axis of a one-way clutch 17.

Abstract: PROBLEM TO BE SOLVED: To eliminate positional errors generated during partial one-shot irradiation by extracting a repetition pattern having no pattern connection with the same line width on a partial one-shot electron-beam lithography boundary, from a design pattern data by mask data extraction processing. SOLUTION: In the case where a gate pattern 1 is repeatedly laid out in X-axis and Y-axis directions in a memory cell region, a pattern group is mechanically divided from a pattern laid out on the leftmost and lowermost part of the memory cell region, using a maximum irradiation size 2 which enables partial one-shot lithography. The pattern group is then extracted. Subsequently, it is checked whether or not divided patterns exist in the extracted pattern group. If divided patterns 9 exist, the divided patterns 9 are deleted from the extracted pattern group 10.
