Filed: 1983-05-18
Abstract: PURPOSE:To facilitate the work and to improve the workability by adding at least inorganic filler of inorganic filler and pigment to thermosetting resin of a prepreg sheathing insulating material, thereby eliminating the sticky property. CONSTITUTION:An inorganic filler 7 is added to thermosetting resin 6 of prepreg sheathing insulator 4a, and a layer of the filler 7 is formed on one side surface of the insulator 4a. In other words, glass fiber 5 is impregnated with the resin 6, and when the resin 6 is B-staged, the filler 7 is added to one side surface. In this manner, the sticky property of the resin B-staged by the filler can be suppressed to reduce the property, an outer insulating layer 3a decreases in the fluidity of the resin 6, the flowout of the resin 6 at the thermosetting time can be eliminated, thereby preventing the layer 3a from being produced with the section only with the fiber 5.

Abstract: PROBLEM TO BE SOLVED: To speed up a data transfer process by dynamically varying the frequencies of polling to respective secondary stations. SOLUTION: A process for determining a polling frequency is activated in certain cycles (S1). In a cycle wherein the polling frequency is determined (Yes in S1), a control part reads data transmission/reception frequencies of the respective secondary stations out of a data transmission/reception table (S2) and finds the data transmission/reception rate of the respective frequencies (S3). The control part determines the polling frequencies of the respective secondary stations by referring to a transmission/reception ratio polling frequency table together with the obtained transmission/reception ratio (S4). Lastly, the control part stores (sets) the determined polling frequencies in the polling frequency table (S5).

Title: Gas fuel supply system for vehicle
Inventor: YAMAZAKI EIJI
IPC: B60K15/01
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To effectively decide failure conditions of a solenoid shutoff valve in a gas fuel supply system for vehicle having likelihood of inclusion of water or moisture. SOLUTION: Pressure should be recovered immediately, if the first shutoff valve is opened fully as in Fig.(f), and the condition shown by thick lines in the graph is generated. If however the first shutoff valve has a failure and does not open sufficiently, the supply of a compressed natural gas becomes short, and the pressure recovery is retarded or does not take place. This is shown by broken lines in the graph, and can be decided by a pressure rise rate threshold ΔP(t). Thus it is possible to diagnose whether the shutoff valve is left closed and cannot be opened, while the vehicle is at a standstill or in driving. In this manner, diagnosis as to if the shutoff valve is operating normally can be made from time to time, to enable prevention of trouble associated with failures in the shutoff valve.
