Title: Surface treatment of plastic material
Inventor: ITOI MICHIO
IPC: C08J7/14
Filed: 1985-04-17
Abstract: PURPOSE:To impart an excellent air diffusing effect, etc., to a porous plastic obtained by sintering small particles of a thermoplastic synthetic resin and molding this sinter by impregnating by coating its surface with a specified inorganic acid and thereby changing the hydrophobic surface into hydrophilic one. CONSTITUTION:Small particles of a thermoplastic synthetic resin such as polypropylene are sintered and molded into a porous plastic material such as a sheet or pipe. The surface of this plastic material is impregnated by coating with an inorganic acid (e.g., conc. sulfuric acid) which does not cause the decomposition of the material but causes its chemical change to change the hydrophobic surface into hydrophilic one. The obtained plastic material can be suitably used for diffuser plates or tubes used in the aeration step in a sewage treatment plant and, in addition, for flowerpots, hydroponic filters, etc.

Abstract: PURPOSE:To transfer only the value of analog information that a monitor station requires by inserting monitor item information which indicates which analog information value is abnormal into the information transferred from a station to be monitored to the monitor station. CONSTITUTION:The station to be monitored adds a value of analog information requested by the monitor station to be transferred or values 2 and 3 of analog information in which abnormality is detected to transfer data and transfers them to the monitor station. In this case, the monitor item information which indicates which analog information is to be transferred is also added as well. Consequently, the monitor station knows which monitor item is abnormal. The station to be monitored, on the other hand, transfers only the monitor item information 8 indicating which analog information value is abnormal to the monitor station firstly, which returns transfer request information 9 of a required value of analog information to the monitor station on the basis of said item information. Then, the station to be monitored converts the corresponding value of analog information into a digital value 10, which is transferred to the monitor station.

Title: Gear shift control device for automatic transmission
Inventor: OKADA TAKASHI
IPC: B60W10/10
Filed: 1987-04-03
Abstract: PURPOSE:To obtain always an optimum speed change ratio regardless of changes in carrying loads by changing speed change patterns according to the loads carried on a vehicle and at the same time setting a speed change pattern for starting the vehicle from the 2nd speed when the load is small. CONSTITUTION:A control device has a load sensor for detecting a load carried by a vehicle and a speed change pattern changing means for changing the speed change pattern according to the load detected by the load sensor. The speed change pattern changing means is constituted such that the speed change pattern is changed so that the vehicle is started from the 2nd speed when the load carried by the vehicle is not greater than a specified value. When the load is greater than the specified value, a large load speed change pattern is selected by means of the speed change pattern changing means. This make it possible to use a relatively high rpm range of an engine to obtain sufficient driving force when the load carried is large.

Abstract: PURPOSE:To decrease a backward voltage applied to a diode by transferring high DC potential diode winding layers, to which a high backward voltage is applied, to the internal layer side of a secondary winding to perform increasing an earth capacity and the like. CONSTITUTION:Windings and the rectifier circuit of a flyback transformer comprise a primary winding L0 and laminated secondary windings L1-L6 divided from said primary winding L0 and a flyback pulse induced by these windings L1-L6 is rectified by a stacked system with diodes D1-D6 each for rectification and outputted to a hightension terminal HV via resistance R. In this case, the secondary winding L6, from which the highest voltage is outputted, is positioned in the third layer, the secondary winding L5, from which the second highest voltage is outputted, in the first layer and the winding L4, in the second layer. As a result, an interlaminar capacity Ci for the sixth stage winding L6 is reduced to about 1/2 and less as the winding L4 line inbetween.

Abstract: PURPOSE:To detect with a high accuracy a distortion quantity corresponding to pressure and strength of force by providing an exciting means for self- exciting a pressure receiving element by a natural frequency. CONSTITUTION:A pressure receiving element 1 is displaced by receiving a force by an elongation of a belows 3 corresponding to a measured pressure. As a result, a resistance of a distortion gauge 6 which is fixed to one end of the pressure receiving element 1 is varied in a state containing a hysteresis and other non-linear component, but a piezoelectric element 7 is fixed to the pressure receiving element 1, and also connected to a self-excited oscillating circuit 8, a vibration of the pressure receiving element is resonated by a natural vibration having an amplitude of the same degree as the quantity of these hysteresis and non-linear component, and an average value of an output of the distortion gauge 6 containing this vibration is detected as an output signal. In this way, the distortion quantity can be detected with a high accuracy by a simple constitution.

Abstract: PURPOSE:To promote safety, by providing a member for reducing the action speed of a control valve for opening and closing a by-pass for connecting the two oil chambers of a power cylinder to each other, so that the supply of pressurized oil to the cylinder is moderated. CONSTITUTION:In a control valve 22A, an oil supply branch passage 17a is connected to a chamber 29a located in front of a spool 28 housed in a cylinder 29, a spring 30 is provided in a compressed state in a chamber 29b located at the rear of the spool and an oil return branch passage 18a is connected to the chamber 29b. The spool 28 is provided with a passage 28a, which functions for the connection of a by-pass 21 when the spool is returned. When the spool 28 is moved by the action of oil pressure to the front chamber 29a, the by-pass 21 is disconnected. When the speed of a vehicle has become lower than a set level and pressurized oil is supplied to a power cylinder 13, the spool 28 is moved to shut the by-pass 21. Since the shutting is made slow by a valve speed reducer 32A, the supply of the pressurized oil is moderated to keep an auxiliary force from sharply increasing.
