Title: Aluminized steel sheet for can and production thereof
Inventor: KAGECHIKA HIROSHI
IPC: C23C28/02
Filed: 1987-12-10
Abstract: PURPOSE:To obtain superior corrosion resistance under a coating film at a low cost and to prevent bimetallic corrosion between steel and Al for a lid by forming an Al layer of a specified thickness as an upper layer by aluminizing and a Cr layer of a specified thickness as a lower layer by electroplating. CONSTITUTION:A Cr layer of 0.005-0.05mum thickness as a lower layer is formed on steel stock by electroplating and an Al layer of >=0.01mum thickness as an upper layer is formed on the lower layer by aluminizing. Since the electrode potential of Cr is between the electrode potential of Al and that of steel, the potential difference between steel and Al is reduced, bimetallic corrosion between them is prevented and corrosion resistance under a coating film can be ensured. Since the Cr layer has a function to galvanically prevent the corrosion of the steel, even when the layer has defects, it has a local corrosion inhibiting effect and prevents the corrosion of the steel satisfactorily in spite of a thin layer thickness.

Filed: 1988-12-12
Abstract: PURPOSE:To always ensure the level of required illumination and at the same time to realize lighting having a feeling of coolness by detecting the rise of temperature in a bathroom and then compensating the fall of light flux in a low color-temperature light source having required illumination at the normal temperature thereof through compound light from a high color-temperature light source. CONSTITUTION:The title illuminator is provided with a low color-temperature light source 1 having required illumination at the normal temperature of a bathroom. A temperature sensor 2 detects a bathroom temperature rising with the use of the bathroom. By this detection result output, an arithmetic unit 3 computes the quantity of a fall in light flux generated from a low color-temperature light source on the basis of existing data regarding the rate of a fall in light flux to ambient temperature. A light adjustment control unit 4 receives this computed fall-value data from the arithmetic unit 3, and then it gives a light adjustment output to a high color-temperature light source 5 for compensating the fall of light flux so that the compensated amount of light flux is allowed to tally with the fall value of light flux computed by the arithmetic unit 3. For this reason, a fall in the quantity of low color- temperature light being caused with the rise of temperature in the bathroom is compensated by high color-temperature light for permitting to obtain compound light having required illumination as well as resulting in the realization of lighting having a better feeling of coolness by the color output of high color-temperature.

Patent JP-S63163875-A (JP)
Title: Blank lamp for electrophotographic copying machine
Inventor: OGAKI SHINJI
IPC: G03G21/00
Filed: 1986-12-26
Abstract: PURPOSE:To improve copy quality by increasing the quantity of light emission of some of light emitting elements which are selected and emit light. CONSTITUTION:When a transistor (TR) Ta3 turns on, a current nearly as much as a rated current flows to a light emitting diode (LED) 3, which emits light by a prescribed quantity enough to discharge a specific area electrostatically. When a TR Tb3 turns on at this time, the parallel circuit of resistances Ra and Rb is formed between the LED 3 and a power source, so a current larger than the rated current flows to the LED 3, which increases in the quantity of light. Thus, when the LED 3 emits light by a large quantity, the illuminance at the exposed part on a photosensitive body 110 is not affected by a partition plate 103. Consequently, the copy quality is improved.

Title: Retainer of rolling bearing
Inventor: KURITA MASAHIRO
IPC: F16C33/38
Filed: 1989-11-30
Abstract: PURPOSE:To give aligning function to an oil film by forming the guide face of a retainer with plural arc-shaped faces which are symmetrical to the center of the retainer and have curvature different from that of a bearing peripheral face, and forming a wedge-shaped clearance between the arc-shaped face and the bearing peripheral face. CONSTITUTION:The bore face of a retainer 1 is formed with plural arc-shaped faces 2 which are symmetrical to the center O of the retainer 1, and formed with plural (as many as the arc-shaped face 2) recesses 4 to form a clearance to the outer peripheral face 7 of an inner ring 6. The arc-shaped face 2 has a radius of curvature larger than that of the outer peripheral face 7, and its central part approaches the outer peripheral face 7 to form a wedge-shaped clearance 3 between the outer peripheral face 7 and itself. Thus, since oil film pressure P of a lubricating oil 8 between the bore face and the outer peripheral face 7 of the retainer 1 is low in the recess 4 and high in the wedge-shaped clearance 3, the pressure P is applied to the retainer 1 from the wedge-shaped clearance 3 toward its center. When the retainer 1 is going to be eccentric in this state, such eccentric motion is forced back by the oil film pressure P, and the inner and outer rings of a bearing are automatically aligned to produce smooth guidance for the retainer.

Title: Frame synchronizing circuit
Inventor: KONO KENJI
IPC: H04J3/06
Filed: 1989-12-04
Abstract: PURPOSE:To operate a frame synchronization circuit even with a clock at high speed and wrong duty ratio by forming a frame counter section with a frame counter and a reference signal generating section. CONSTITUTION:A frame counter 21 stops the operation when no synchronization state is detected by a phase comparator section 3 and starts its operation when the synchronization state is detected. Then a reference signal generating section 22 generates a reference signal outputting a synchronization state detection signal from the phase comparator section 3 when a frame detection signal is outputted by a frame pattern detection section 1 while no synchronization state is detected by the phase comparator section 3 and the phase comparator section 3 generates a reference signal to output the synchronization state detection signal regardless of the output of the frame detection signal by the frame pattern detection section 1 when a synchronization protection section 4 detects the establishment of the synchronization state. Thus, the circuit is operated sufficiently at high speed even a wrong duty ratio clock is used.

Filed: 1986-12-23
Abstract: PURPOSE:To make it possible to uniformly for the time of signal propagation between wirings by a method wherein a part of the insulating film located directly under the wirings is thinly formed, and the time constant of two wirings is made equivalent. CONSTITUTION:A P-type impurity region 5 is formed on a P-type substrate 6, and a selective oxide film 3 is formed by oxidizing said impurity region 5. A nitride film 4 is formed on the film 3, and the wirings 1 and 1' which require uniform signal propagating time are formed thereon. As the wiring 1 has large input impedance, parasitic capacitance and resistance, its capacitance with respect to the substrate is increased by thinning the film 3 located directly under the wiring 1', and the wirings 1 and 1' are made equal in the time constant to each other. As a result, the signal propagating time can be made uniform without increasing the number of processed and the number of elements.
