Title: Ink jet recording device
Inventor: HIRABAYASHI HIROMITSU
IPC: B41J2/12
Filed: 1991-08-01
Abstract: PURPOSE:To make a discharge volume stable, then widen a temperature range and stabilize image quality without recording speed reduction by estimating the ink temperature of a recording head and maintaining the ink temperature at a higher level than an ambient temperature. CONSTITUTION:An auxiliary heater for temperature adjustment 8a, a train of discharge parts 8g where a main heater for discharge is arranged and a drive element 8h are formed on a single substrate. The temperature variation of a discharge part is estimated and forecast by assessing said variation using a temperature variation table indicating the thermal time constant of the discharge part including a recording head and ink as well as energy charged in a range from the past to the future relative to an ink temperature calculated previously. For example, if the retained temperature is set to 20 deg.C, an upper limit temperature which is controllable by PWM is 38 deg.C when an ink jet recording device is used under normal environments. If it is operated under high temperature environments at about 30 deg.C, the temperature range in which the discharge volume can be controlled is 38 deg.C. Therefore, the retained temperature which is higher than an environmental temperature is set to 36 deg.C with the help of the auxiliary heater 8d, so that the upper limit temperature is 54 deg.C and the temperature range in which the discharge volume can be controlled is narrow, resulting in a stable discharge volume.

Title: Manufacture of alkaline manganese battery
Inventor: NAGAMINE AKIO
IPC: H01M4/50
Filed: 1981-12-02
Abstract: PURPOSE:To allow to hold a large amount of alkaline electrolyte in a positive black mix and increase high rate discharge performance and the performance at low temperature by freeze-drying a mixture of manganese dioxide containing an electrolyte and keeping 3-9% moisture content after drying. CONSTITUTION:Manganese dioxide and conductive carbon material such as flake graphite are mixed and an alkaline electrolyte is added to prepare a uniform mixture. This mixture is freeze-dried to obtain a positive mix 2 containing 3- 9% moisture. Freeze-drying is a method that the moisture in the black mix is freezed, and freezed moisture is sublimed under a reduced pressure to remove moisture as vapor for drying. Because the black mix containing an alkaline electrolyte is freeze-dried under reduced pressure, absorption of carbon dioxide gas in the air is prevented. Therefore, increase of internal resistance of a battery caused by absorption of carbon dioxide is eliminated.

Title: Patterning method of positive resist
Inventor: MORIYAMA ICHIROU
IPC: G03F7/16
Filed: 1982-11-04
Abstract: PURPOSE:To obtain a pattern having steep cut surface by treating a surface of a resist film with strongly alkaline solution in advance of exposure in process of patterning on a resist film by forming the resist film composed of novolak- group resin containing o-naphthoquinonediazide group as photosensitive radical on a material to be etched, followed by the exposure and development. CONSTITUTION:When a compound containing o-naphthoquinonediazide group is treated with strongly alkaline solution such a KOH, NaOH or developing solution, condensation shown in the figure occurs to generate azo-compound. Accordingly, if the resist surface is bathed in strongly alkaline solution in advance of exposure, azo-compound is generated in a compound containing o-naphthoquinonediazide group as the surface, and further it is diffused in the resist so that concentration of molecules relating to photosensitivity becomes lower in adjacency of the surface. The result condition is illustrated in the figure where a borderline of non-photosensitive region 1 and photosensitive region 2 of the resist film formed on a substrate 3 is nearly vertical and wall of the left region 2 becomes steep.

IPC: H01F41/02
Filed: 1985-09-02
Abstract: PURPOSE:To prevent a coil from deteriorating in high frequency characteristics, by fixing a magnetic core with a thermal-shrinkable tube. CONSTITUTION:A coil 3 is arranged in a coil contraction space which is formed by combining EE-shaped cores 1 and 2, and then the cores 1 and 2 are butted, covered with a thermal-shrinkable tube 4, and heated for fixing. Then, the tube width (a) is made larger than the core width (b) so that the side parts of the cores 1 and 2 can be covered when heated and shrunk. In case of necessity of covering, the whole can correspond to fully enlarging the tube width (a), and the tube can be inserted from the (c) direction in addition to a direction of inserting the tube. Putting the tube doubly in the two directions enables the core to be completely insulated. Hence, the housed coil is prevented from deteriorating in high frequency characteristics.

Abstract: PURPOSE:To suppress the switching frequency and to prevent the deterioration and noise occurrence of the device by applying hysteresis characteristics when a part of intake valves and exhaust valves is switched to a valve pause state or a valve action state in accordance with operating conditions. CONSTITUTION:A control circuit controlling solenoids 24A, 24B of individual valve drive mechanisms selectively pausing multiple intake valves and exhaust valves compares the output Vn from a rotation voltage generator circuit 30 composed of an AC generator ACG rotating in synchronous with engine rotations and its rectifying/smoothing circuit with a reference voltage Vr in a comparator circuit 31. This comparator circuit 31 outputs a voltage -VOM when the input voltage Vn exceeds the voltage Vr+DELTAV1 and outputs a voltage +VOM when the input voltage Vn is less than the voltage Vr-DELTAV2, i.e., feeds the output with hysteresis characteristics to drive the solenoids 24A, 24B through a switch 32. Accordingly, the frequency of switching between a valve action state or a valve pause state in accordance with the engine speed can be suppressed, thereby the deterioration and noise occurrence can be prevented.
