Abstract: PURPOSE: To prepare an iron blue pigment with an improved coloring power and giving an beautiful violet hue, by precipitating a Berliner white dough from sodium hexacyanoferrate (II) and washing this dough by decantation until it is free of salt.  
     CONSTITUTION: An aqueous solution of sodium hexacyanoferrate (II) is mixed with aqueous solutions of ammonium sulfate and iron (II) sulfate, and a white dough is precipitated until an excess of iron up to 1.4 to 1.7 g/l, calculated as Fe, is attained in the filtrate.

Title: Air conditioning system
Inventor: HOJO TOSHIYUKI
IPC: F25B41/04
Filed: 1990-11-21
Abstract: PURPOSE:To efficiently use retained refrigerant for operation with expansion of retained refrigerant by providing a gas cooling branch pipe, a bypass pipe to a liquid refrigerant branch pipe and a flow control valves on the bypass pipe. CONSTITUTION:In the case an indoor unit 2a is stopped and an indoor unit 2b is in operation, refrigerant retained in a high pressure gas refrigerant branch pipe 21a flows through a bypass pipe 24a and discharges into a high pressure refrigerant branch pipe 23a when a flow regulating valve 18a is opened. At this time, as a cooling changeover solenoid valve 12a is opened, the pressure of a room-side heat exchanger 10a drops nearly to the suction pressure Ps of a compressor 2, so that refrigerant is prevented from being retained. Then, in the case the indoor unit 2a carries out cooling operation and the indoor unit 2b performs heating operation, a heating changeover solenoid valve 11a is closed, the cooling changeover solenoid valve 12a is opened, a room-side expansion valve 9a is opened, a heating changeover valve 11b is opened, a cooling changeover valve 12b is closed, and a room-side expansion valve 9b is opened. Then, when the flow regulating valve 18a is opened, retained refrigerant is discharged to the high pressure refrigerant branch pipe 23a through a bypass pipe 24a.

Title: Line pressure control device for automatic transmission
Inventor: WAKAHARA TATSUO
IPC: F16H61/00
Filed: 1990-11-21
Abstract: PURPOSE:To improve control accuracy by changing a relation of a line pressure relating to a duty oil pressure or a duty oil pressure corresponding pressure, and using the relatively high duty oil pressure or duty oil pressure corresponding pressure. CONSTITUTION:Since a line pressure acting in a gain change port 112, in a predetermined speed change shift, is matched with a duty oil pressure or a duty oil pressure corresponding pressure acting in a pilot port 126 with a line pressure acting in a feedback port 114, the line pressure obtains a relatively low value relating to the relatively high duty oil pressure or duty oil pressure corresponding pressure. Accordingly, even in a condition that a low oil pressure is governed, the duty oil pressure or duty oil pressure corresponding pressure obtains a relatively high value, and duty ratio, given to a solenoid 97, obtains a relatively large value. In this way, stable control of the oil pressure can be performed by improving control accuracy.

IPC: G01B7/00
Filed: 1993-12-16
Abstract: PURPOSE:To sufficiently protect magnetic track at low costs by so attaching a resin tape to cover the magnetic track needed for position detection. CONSTITUTION:A magnetic body 2 of low rigidity such as a thin plate-like magnetic material is fixed to a scale base 3 such as an iron of high rigidity. To a position detection unit 5 mounted to slide freely, with a specified distance from the magnetic body 2 kept, a magnetoresistance element 12 for reading magnetic scale of the magnetic body 2 is provided, and the detected signal is led out by a lead 14. A resin tape 1 is so attached to cover the surface of magnetic scale recorded on the magnetic body 2. Here, magnetic scale track width (c) of magnetic body 2 is always larger than track width (a) (detection width of element 12 plus such conditions as mounting tolerance) for detection. Therefore, the tape 1 is so attached to, at least, cover the track width (a) even if the track width (c) is sufficiently larger than the track width (a). With this, the magnetic track is sufficiently protected from external pressure and oxidation.

Title: Pedometer
Inventor: TASAKA ISAO
IPC: A61B5/11
Filed: 1988-12-15
Abstract: PURPOSE:To accurately measure the number of steps regardless of a place for walking, a pair of shoes, a mode of walking, etc., by equipping the title pedometer with a selecting part to select which walk signal out of respective walk signals from an upper detecting part and a lower detecting part is to be made into the object of counting, etc. CONSTITUTION:The output of an acceleration sensor 1 is inputted through a selecting part 2 to one out of an upper side comparator 3a as the upper detecting part and a lower side comparator 3b as the lower detecting part. The upper side comparator 3a has a prescribed threshold Th1, and when the output of the acceleration sensor 1 is inputted to the comparator 3a, the comparator 3a inverts the output and generates a pulselike walk signal only during a period in which the absolute value of the output voltage is >= the threshold Th1. On the other hand, the lower side comparator 3b inverts the output and generates another pulselike walk signal only during a period in which the absolute value of the output voltage is >=Th2. Further, only one walk signal is taken out for one step, and the number of the steps can be accurately measured by making only the walk signal generated first into an effective signal even when plural walk signals are generated for one step.

IPC: F02D35/00
Filed: 1987-12-17
Abstract: PURPOSE:To simplify a circuit structure by housing a temperature sensing sensor in an ignition control case which houses a lead angle operating circuit. CONSTITUTION:In an internal combustion engine, an ignition control case 25 which composes a CDI ignition unit is fixed to the side portion of an engine body 17. The ignition control case 25 houses an ignition circuit base board 26 and a temperature sensing sensor 27 by means of a mold resin 28. The ignition circuit base board 26 includes a lead angle operating circuit, a diode, a capacitor, and an SCR. Thus, since the temperature sensing sensor 27 is also housed in the ignition control case 25 which houses the lead angle operating circuit, it is not necessary to provide such long wiring as to connect the temperature sensing sensor 27 to the lead angle operating circuit on the outer face of an engine, simplifying a circuit structure.
