Title: Device and method for sigmal-delta modulation with improved tone removal function
Inventor: ROBAATO SHII RETSUDOJIUSU
IPC: H03M3/02
Filed: 1994-03-09
Abstract: PURPOSE: To obtain a sigma/delta modulator for removing an in-band tone. CONSTITUTION: Modulators 50 and 100 attenuate the frequency area frequencies of a signal feedbacked to a first stage 60 to the neighborhood of fS/2. The fS is the clock frequencies of the modulator. The modulator substantially removes an in-band tone known in the field of a sigma/delta modulator, and unnecessitates any complicate dither technique. The feedback loop of the modulator 50 includes a two tap finite impulse response FIR filter 80. This smoothly switches the transition, and provides a feedback signal from the output of a second stage 70 to a first stage 60. This structure is valid to either the digital/ analog sigma/delta modulator 50 or an analog/digital sigma/delta modulator.

Title: Coolant inlet and outlet guide unit for liquid-cooled rotor type rotary electric machine
Inventor: OKAMOTO KOUICHI
IPC: H02K9/19
Filed: 1979-05-22
Abstract: PURPOSE:To enhance the corrosion resistance of the inner wall of an outlet chamber at a coolant inlet and outlet guide unit for a liquid-cooled rotor type rotary electric machine and prevent occurrence of noise thereat by forming an L-shaped cross sectional exhaust ring at the opening of an outflowing tube for discharging coolant into the outlet chamber so as to surround the opening and thus discharging axially the coolant from the exhaust passage. CONSTITUTION:An L-shaped cross sectional exhaust ring 11 is so mounted at the exhaut portion for discharging coolant into an outlet chamber 612 from the exhaust passage 31b of a coolant supply and exhaust tube 41 as to form a container 11a surrounding the opening of the exhaust passage 31b. An axial exhaust passage 12 is so formed at the portion making contact with the outer peripheral surface of the inflowing tube 21 of the ring 11 as to be inclined in a direction opposite to the rotating direction of a rotary shaft to exhaust the coolant into the outlet chamaber 612. In this manner, this configuration can decelerate the speed of the coolant in radially outward direction, prevent the coolant from colliding with the inner wall of the outlet chamber 612 and also prevents occurrence of corrosion and noise at the inner wall of the outlet chamber.

Title: Continuous variable transmission
Inventor: ESU DABURIYU EMU BAN BIYUUREN
IPC: F16H37/02
Filed: 1991-03-07
Abstract: PURPOSE: To prevent the friction of a continuously variable transmission and pulleys and increase transmission efficiency by providing a slip preventing means preventing an endless transmission element from being slipped between the pulleys on the transmission. CONSTITUTION: A blade 11 provided on a clutch 10 transmits large torque from an in-going shaft 1 to a secondary shaft 2 by the frictional contact between the blade 11 and a plunger 12 when the blade 11 is strongly compressed by the plunger 12 and transmits small torque when it is weakly compressed. The fluid pressure in a cylinder 13 for the plunger 12 to compress the blade 11 of the clutch 10 is adjusted so that the maximum torque transmitted by the clutch 10 is invariably made smaller, preferably slightly smaller, than the torque when an endless transmission element 8 is slipped on pulleys. The clutch 10 is slipped faster than the endless transmission element 8 under all conditions for this purpose.

Title: Image forming device

IPC: G03G21/00
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To maintain an image of high quality over a long period by selectively using an electrifying means, an exposing means and a developing means out of plural electrifying, exposing and developing means. SOLUTION: When a single color of black is specified by a user, the light emission cumulative times used before the specification of first and second laser light emitting devices are calculated/compared by a main CPU, based on the information of a storage part. The laser light emitting device whose cumulative time is shorter is used to form a laser beam. Further, as an electrifier, when a first laser beam L1 is selected, a first electrifier 2 is automatically selected and when a second laser beam L2 is selected, cumulative energizing times are calculated/compared with the information in the storage part, in the same way as the laser beam and the electrifier whose cumulative time is shorter can be selected. Thus, either of the electrifying, exposing and developing means is selectively used.

Title: Electric foot warmer
Inventor: HOSAKA MASATO
IPC: F24H3/04
Filed: 1989-03-16
Abstract: PURPOSE:To eliminate inside odor by installing an insulator around an electric resistance heat generating body, a heat resistant porous layer around its outer periphery, which supports a platinum-based catalyst for an electric heat generating body. CONSTITUTION:When electric power is supplied to an electric resistance heat generating body 12, an insulator 13 provided around the heating element is subjected to high temperature. A heat resistant porous layer 14, which supports platinum-based catalyst 15, is provided around the outside of the insulator 13, which subjects the heat resistant porous layer 14 to high temperature as well and raises the temperature of the platinum-based catalyst 15 up to active temperature. The air, which circulates inside a 'kotatsu' or foot warmer by a centrifugal fan 8, is brought into contact with the platinum-based catalyst 15 when it is passing through the electric heating element 10 so that the catalyst 15 is raised up to the satisfactory active temperature which allows catalysis to be exerted. Therefore, the air which contains the odor inside the foot warmer is cleaned by the catalysis so that the odor may be eliminated. It is, therefore, possible to use the foot warmer for a long time, eliminating body smell from the inside of the foot warmer.

IPC: H04L29/08
Filed: 1993-03-02
Abstract: PURPOSE:To attain the setting of a period of a wakeup pulse without being affected by oscillation operation stabilization time of a master station. CONSTITUTION:A 2nd timer 110 is provided to continue the oscillation of an oscillation circuit 105 during prescribed counts after a sleep execution command. A counter 108 outputs a count-up signal being both one of wakeup pulses and plural pulses and when the pulse is received after the end of counting by the timer, the sleep state is released by one pulse. Moreover, when the signal is received while counting, a selector 111 is switched to release plural pulses. Thus, even when a noise invades just after sleep command, the noise is identified and eliminated and since the oscillation continues to the wake-up pulse, the period of the wake-up pulse is set without being affected by an oscillation stabilizing time.
