Title: Controller for fixing heater
Inventor: IWATA ATSUTAKA
IPC: G03G15/20
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce an adverse effect such as the flicker of a fluorescent lamp caused by the fluctuation of a power source voltage and exerted on the other electric equipment by providing a device with a control means turning on or off a fixing heater at an interval being equal to or longer than a set time so as to conduct. SOLUTION: This device is provided with the control means 4 controlling the fixing heater 2 to be turned on or off. The control means 4 is provided with a time measurement means. Then, the heater 2 is controlled to be turned on or off by an AC power source 5 based on prescribed switching processing according to the detection output of a temperature detection means 3. By the control means 4, the on/off switching processing is judged, that means, it is judged by the time signal of the time measurement means whether the previously set time elapses or not after the heater 3 is turned off. When more than the set time elapses, the temperature value of a fixing roller 1 detected by the detection means 3 is compared with a target value. When the temperature value of the roller 1 is equal to or under the target value, the heater 2 is turned on.

Inventor: TAKASHIMA NOBUTSUGU
IPC: C22C38/00
Filed: 1990-03-28
Abstract: PURPOSE:To reduce the work hardenability of a non-magnetic steel without impairing its fundamental characteristics and to permet its drilling or deep drawing without cracking by controlling its chemical components, metallic structure and the content of non-metallic inclusions. CONSTITUTION:This high Mn non-magnetic steel is a one contg. 0.15 to 0.70% C, 0.10 to 3.00% Si and 12 to 30% Mn, in which the content of C and Mn furthermore satisfies the inequality and the balance Fe as well as in which the fractional rate of unrecrytallized grains in an austenitic structure is regulated to <=50% and the content of non-metallic inclusions is regulated to <=0.03% in cleanliness. In this steel, fundamentally, C and Mn stabilize austenite to secure its non-magnetic properties, but in the case the content of both C and MN lies in the vicinity of the lower limit of the above defining range, austenite is made unstable. For preventing this, the above inequality shall be satisfied. As for the fractional rate of unrecrystallized grains, its notch elongation is reduced as it increases, and in the case of >50%, the notch elongation is rapidly reduced, and furthermore, as for the cleanliness, in the case of <=0.03%, the notch elongation rapidly increases, so that each is regulated in the above-mentioned manner.

Title: Heat exchanger
Inventor: ANDO TOMOAKI
IPC: F28F1/32
Filed: 1985-04-18
Abstract: PURPOSE:To permit the elongation of operating time during frosting by a method wherein the heat exchanger is constituted of the group of fins formed with recesses and protrusions, slanted with respect to the inflow direction of air, on the inflow side end of air and the group of heat transfer tubes, through which fluid is flowed. CONSTITUTION:The air, flowed into the heat exchanger 6, contacts at first with the crest 12 of the protrusion 13 and effects heat exchange. The difference of absolute humidity between the inflow air and the crest 12 of the protrusion 13 is very large, therefore, the amount of frost adhered to the crest 12 of the protrusion 13 is very large. Next, the inflow air contacts with the trough 11 of the recess 14 and effects heat exchange. In this case, the trough 11 of the recess 14 is closed to the group 7 of heat transfer tubes, through which low-temperature fluid is flowed,therefore, the surface temperature of the tubes is lower than the same of the crest 12 of the protrusion 13. However, most of the inflow air is dehumidified already at the protrusion13 and the difference of absolute humidity between the inflow air and the trough 11 of the recess 14 is smaller compared with the same between the inflow air and the crest 12 of protrusion 13, therefore, the amount of frost, adhered to the trough 11 of the recess 14, is small.

Title: Flame detector
Inventor: KOMORI TOSHIYUKI
IPC: G01J1/42
Filed: 1980-06-20
Abstract: PURPOSE: To monitor the state of flames by disposing a variable resistance element responding to flames on field side, and a load and a power source on the central side, connecting these in series and detecting the change in the voltage across the load.  
     CONSTITUTION: An AC power source 23 for calibration in the central side is fed simultaneously with a DC power source 21 for measurement to a field by a switch 22 via a 2-wire type transmission line. By a separator 31, the AC flows from a terminal 30 to a liquid crystal driving circuit 34 and a liquid crystal 33 acting as a shutter, thereby operating the liquid crystal and applying a flame absent state to a flame sensor 32. The sensor 32, an amplifier 35 and a variable resistance element 36 are supplied with power from the DC terminal 29 of the separator 31, and the power returns to the DC power source 21. The operator confirms that the voltage across a load 20 is indicating flame absence. Thence, when the operator opens the  switch 22 to set a measurement state, the liquid crystal 33 goes transparent and the  sensor 32 outputs a flame signal, thus the voltage across the load 20 indicates the  state of flames in the same manner as that at the calibration. Thereby, the detector  having a checking function is constituted.

CONSTITUTION:A positioning pin 25 of a stationary mold 11 is inserted into a positioning hole 32 of a core material 30. Sprue 17 is filled with molten resin through an injection machine in a mold clamping state, the molten resin arrives at the central part of a cavity 15, abuts against a bushing 18 and ejector pin 19 through a resin circulation hole 31 of the core material 30 and charged toward the fringe of the cavity 15 through a space among the core material 30 and each of mold surfaces 13a, 14a. Therefore, injection pressure is hardly applied to the surface of the core material 30 and a deformation can be prevented. As both surfaces of the core material 30 are pressed by press pins 26, 28, the core material 30 can maintain a state wherein the same runs parallel with both the mold surfaces 13a, 14a and a resin layer 52 covering both the surfaces of the core material can be made into a uniform thickness extending over the whole surface.

Abstract: PURPOSE:To prevent an engine speed from dropping, by compensating a reduction in the suction quantity caused by a supply stop of suction air by a suction feeding device after the elapse of a given period of time from hot restarting with an idling speed regulating device. CONSTITUTION:During a given period of time after hot restarting, fuel is also fed out of a second fuel feeding device 12 together with suction air out of a suction feeding device in addition to fuel feed out of a first fuel feeding device. Therefore, with the occurrence of air bubbles in fuel out of the device 11, an air-fuel ratio is prevented from being lean by a fuel supply by the device 12 whereby the air-fuel ratio becomes proper and an engine start at the time of hot restarting is improved so better. Afterward, if the specified time elapses, the feed of suction air by the device 24 is stopped, but simultaneously with this, an idling speed regulating device 22 is compensated by a compensating device 25, so that suction air almost nearly commensurate to a suction quantity out of the device 24 is supplied. Accordingly, a drop in an engine speed is prevented from occurring.

Title: Digital signal recording method

IPC: G11B5/09
Filed: 1986-04-11
Abstract: PURPOSE:To prevent adjacent data in the same positions from recording start positions of respective tracks from being erroneous together because of a flaw or the like which occurs in the lengthwise direction of a recording medium, by not linearly arranging recording start positions of plural tracks simultaneously formed in the lengthwise direction of the tape. CONSTITUTION:With respect to a recording track pattern, recording start positions of tracks TA' and TB' are shifted from each other by a length W in the breadthwise direction of a tape. That is, recording start positions of tracks TA' and TB' are not linearly arranged in the lengthwise direction of the tape 17. This arrangement is realized if recording start positions in the track direction of tracks TA' and TB' are shifted from each other by a length L2 of positional deviation in the rotating direction between heads HA and HB. Though a flaw occurs in the lengthwise direction of the tape, data in the same positions in the track direction from recording start positions of tracks TA' and TB' are prevented from being erroneous together because of this flaw.
