Title: Heater disconnection detecting apparatus
Inventor: FUJIMOTO RYOICHI
IPC: G05D23/19
Filed: 1994-10-19
Abstract: PURPOSE: To surely detect disconnection of a plurality of heaters and lower the manufacturing cost of a heater disconnection detecting apparatus by switching the connection of the heaters between series connection and parallel connection at the time of warming up and detecting the temperature rising state of a heating medium. CONSTITUTION: When an electric power switch is turned on, exciting current is supplied to a coil C and terminals COM and NO are connected in a relay 140. As a result, a main heater 32, an electric power source 110, and a subheater 33 are connected in series. A CPU 102 supplies a control signal to an LED 121 of a switch 120 to open electric communication of a bilateral SCR 122. In the case the temperature of a fixing roller does not rise and reach the a threshold temperature θ1 even if a time t1 passes, the temperature data is supplied from a thermistor 40 to the CPU 102 and the CPU determines that disconnection occurs in either one of heaters 32, 33. After a time t1 passes, the CPU 102 supplies electricity only to the heater 32. In the case the temperature of the roller reaches θ2 after a time t2 passes, it is judged that disconnection occurs in the heater 33.

Title: Soft ground reinforcing method
Inventor: UCHIDA JUN
IPC: C09K17/00
Filed: 1992-09-24
Abstract: PURPOSE:To improve quality in executing works for solidifying ground with hardening injection material slurry and high-pressure air supplied thereto while a multitubular pipe penetrated into soft ground are extracted being rotated by specifying the composition of the slurry. CONSTITUTION:Slurry containing cement, dispersing agent, water-soluble silicate containing SiO2 in 0.02-20 times the solid fraction of the dispersing agent by weight, silica sol and silicic acid water-containing gel is prepared as hardening injection material slurry. As this slurry and high-pressure air are supplied into a multitubular pipe and the pipe is rotated, earth in the ground is scraped off. Then, by rotation and extraction of the pipe, the scraped-off earth and the slurry are mixed together and thereby soil dispersing slurry is formed in the ground. During solidification process thereof, the additive such as water-soluble silicate effectively prevents moisture in the slurry from being separated, and bleeding of water can be restrained therewith. Thereby the bleeding that is common in conventional way of excavation can be prevented and excavation in the direction of radius can be made in a large scale while ensuring smooth execution of work.

Title: Torque fluctuation reducing device for internal combustion engine
Inventor: SHINSHI MAMORU
IPC: F02B75/06
Filed: 1984-12-04
Abstract: PURPOSE:To control the amount of fluctuation of torque within a desired value in an internal combustion engine which has on its rotating shaft an electrical rotary machine which is switchable to a generator or a motor by changing the switching timing in response to the battery terminal voltage. CONSTITUTION:An internal combustion engine 2 experiences a reduction of the angular speed during the compression stroke, and an increase during the explosion stroke. In order to cope with such, a counter torque is given to the internal combustion engine 2 by comparing the angular speed as detected by a detecting means 6 such as a crank angle sensor etc. with the predetermined switching angular speed by a first control means 8, and operating an electrical rotary machine 4 as a generator if the detected angular speed exceeds the switching angular speed. If the comparison is contrary to the above, the electrical rotary machine 4 is operated as a synchronized motor to yield a supplemental driving torque. The switching angular speed is determined by correcting the basic average angular speed of the crankshaft by a second control means 12 in proportion to the terminal voltage of a battery 10.

Abstract: PURPOSE: To obtain a high density image by setting a space for accumulating a toner in such a way that the ear of a developing agent held on a developing agent holding member is not brought into contact with the developing agent accumulated in the space for accumulating the toner. CONSTITUTION: A printing head 200 forms a space A for accumulating a toner by the inner peripheral face of a hole 23a of an electrode 21 and the surrounding of a hole 23b of an insulation layer 20. This space A for accumulating a toner is set in such a way that the ear of a developing agent held on a toner feeding roller 1 as a developing agent holding member is not brought into contact with the toner accumulated in the space A for accumulating the toner. This setting results in no possibility that the toner 42 accumulated in the space for accumulating the toner is not scraped out by means of a carrier 41 of the ear of the developing agent. As the result, as the amt. of the toner passing through a toner passing-through hole 23 increases during printing, a high density image can be obtd.

Title: Power steering
Inventor: WATANABE OSAMU
IPC: B62D5/22
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To damp what is called kick back, reversely inputted to a pinion shaft through a rack shaft, by viscous shearing resistance of a viscous fluid by sealing the viscous fluid in a closed chamber formed between a housing and the pinion shaft. SOLUTION: A power steering consists of a first member 42 of ring shape formed of metal or resin and engaged with a serration part 41, formed at one end of a pinion shaft 31, so as to be rotated integrally with the pinion shaft 31, and a second member 44 of ring shape formed of metal or resin and fittingly fixed into an annular hole formed in a gear housing 11. A viscous fluid 46 formed of silicone oil or the like is sealed in an annular chamber 45 formed between the first member 42 and second member 44 being sealed by sealing members 47, 48. Viscous shearing resistance of the viscous fluid 46 becomes larger with the increase of rotating speed at the time of the first member 42 and second member 44 being relatively displaced.  Rotation caused by kick back is considerably damped by viscous shearing resistance of the viscous fluid 46, so that reverse input is hardly transmitted to a steering wheel.
