Title: Resonance type inverter device
Inventor: ISHII TAKAYUKI
IPC: H02M7/523
Filed: 1993-09-30
Abstract: PURPOSE:To make it possible to reduce losses in a broad load range by changing the minimum value of a resonant DC voltage in response to the load factor of the output load, and switching the ON/OFF pattern of a main switching element with the minimum voltage value. CONSTITUTION:With a resonance circuit 4 constituted of a reactor 2 and a capacitor 3, which are connected to a DC voltage source 1 in parallel, the resonant DC voltage generated across both ends of the capacitor 3 is suppressed to a constant voltage or less. At this time, the charging and discharging state of a capacitor 11 is detected from the output of a detecting circuit 17, which detects the current flowing through a series circuit 12 of the capacitor 11 and a switching element (Tr) 8 that are connected to the reactor 2 in parallel. The ON/OFF operation of the Tr 8 of the series circuit 12 is controlled with switching element control means 18 and 19, and the charging and discharging amounts for the capacitor 11 are controlled. Namely, the ON/OFF pattern is switched at a period where the resonant DC voltage becomes zero when the load factor is large, and the ON/OFF pattern is switched at a period where the resonant DC voltage becomes the minimum low-voltage value when the load factor is small.

Abstract: PURPOSE:To manufacture an Al alloy sheet excellent in strength and formability with superior productivity, by subjecting an ingot of Al alloy containing specific amounts of Mn, Mg, Si, Fe, and Cu to heat treatment and then working the above into a metal sheet by means of hot and cold rollings. CONSTITUTION:An ingot of Al alloy having a composition containing, by weight, 0.5-1.5% Mn, 0.5-2.0% Mg, 0.1-0.8% Si, 0.1-0.8% Fe, and 0.1-0.4% Cu is subjected to soaking treatment at >=580 deg.C for >=2hr. Subsequently, the above ingot is cooled down to a temp. in the range of 450-550 deg.C, held at that temp. for >=2hr, and then hot-rolled into a metal plate under the conditions in which draft in the final pass and rolling-finishing temp. are regulated to >=40% and >=310 deg.C, respectively, followed by coiling. This hot-rolled coil is subjected to forced cooling and then cold-rolled, by which a metal sheet of the desired final thickness can be manufactured. By this method, the cold-rolled Al-alloy sheet having uniform structure and properties over the whole length and width of the sheet metal and excellent in strength and formability as a material for cans, etc., can be manufactured.

Title: Digital impulse noise absorbing circuit
Inventor: HATSUTORI TAKAHIKO
IPC: G11B20/10
Filed: 1983-12-26
Abstract: PURPOSE:To absorb impulse noise by applying fade-out and fade-in to a signal before and after an erroneous signal in a digital signal demodulating circuit of a digital audio signal. CONSTITUTION:A demodulate data 1a of a demodulation circuit 1 enters a delay circuit 2 and the data enters a bit shift circuit 10 as a data 2a with a delay of N-word. A P-S shift circuit 3 is activated with a clock signal 9a and in case of fade-out, an output (inhibiting signal) 7a of an up-counter 7 goes to logical ''1'' for a duration period (p), and a shift clock SCK is inhibited by a gate circuit 9. An S-P shift circuit 4 receives each bit being the MSB or below, applies parallel conversion and outputs a corrected demodulation data 4a. The corrected demodulation data 4a shifts right the signal 2a and decreases the amplitude so as to form the fade-out state. Then when the signal is applied with N-word delay, the system is brought into the muting state. The system enters the fade-in state during the muting state and restores to the normal state finally.

Inventor: YASUGADAIRA MASAHIKO
IPC: B60R19/24
Filed: 1993-09-30
Abstract: PURPOSE:To prevent mutual interference of mating parts in the vertical direction between a front bumper and a car main body in mounting the front bumper on the car main body while conducting positioning in the vertical direction. CONSTITUTION:An eccentric rotary body 21 is rotatably inserted into a fixed body fixed to a hood ridge panel 9.

IPC: G03H1/02
Filed: 1985-10-31
Abstract: PURPOSE:To increase the volume of stored information and make a reading system small-sized and lightweight by providing an optical waveguide layer, an optical coupler which takes irradiated light for reading into the optical waveguide layer, and holograms of stored information formed in recessed parts provided in the upper layer part of the optical waveguide layer. CONSTITUTION:An optical waveguide layer 23 is provided with an optical coupler 27, which is formed by waving a part of the upper layer part, and many recessed parts 24 (data bits) where holograms are received, and light reflection preventing layers 28 are stuck to end faces of this layer 23.

Title: Paper feeding/separating device for facsimile machine or copying machine
Inventor: MORADO EMU SAMII
IPC: B65H3/52
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent feed of two or more sheets at a time over a separator pad by providing a sheet feed spring in which resistance added to a first eccentric part of the sheet feed spring by rotation of a separator roller is fluctuated, and in which resistance added to a cylindrical part of a separator spring is constant. SOLUTION: A front edge part of a sheet stack extended on a rack part 18 is applied to a separator roller 20 of rubber, and downward force is provided by a sheet feed spring 24 to the sheet stack 14. As a separator roller 20 is rotated, plural sheets are pulled into a machine by friction between the separator roller 2 and a bottommost sheet, and friction between the bottommost sheet and the sheet positioned above that. A separator pad 26 of rubber downwardly deflected by a separator spring 27 prohibits all the sheets other than the bottommost sheet. As a result, only the bottommost sheet which directly gets in contact with the separator roller 20 of rubber is fed over the separator pad 26.

Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a fan by forming an annular part between a fan casing and a top surface of a diffuser, and bonding the annular part to the top surface of the diffuser for integration. SOLUTION: An annular part 24 is formed between a fan casing and a top surface of a diffuser, and the annular part 24 is bonded to the top surface of the diffuser for integration, and a clearance formed by rugged parts of the fan casing is thereby sealed by a flat surface 22, which contacts with the fan casing, and a clearance due to drop or deformation of the diffuser is sealed by bonding to the top surface of the diffuser so as to restrict the lowering of performance at the minimum. Generation of flutter of a sheet due to the air flowing in a diffuser flow passage in the case where the sheet is interposed is prevented by forming the annular part 24 from the same material of the diffuser or the similar synthetic resin and having rigidity, and lowering of performance of an electric fan due to the generation of noise and increase of the air resistance can be prevented.
