Abstract: PURPOSE:To make it possible to decrease the delay in compensation for electric inertia by detecting rotary angle acceleration based on only the responses of a shaft torque meter and a load cell. CONSTITUTION:Driving force for a vehicle under test is transmitted to the shaft of a shaft torque meter 101 through a driving wheel 11 and a drum means 12. As a result, a rotary angle acceleration omega is generated in the shaft of the meter 101. Then a detected torque value Tf of the mete 101 becomes the value of the expression I, where Wm1 is the inertia of an electric dynamometer 1 observed from the torque meter, and Tt is the absorbed torque of the dynamometer 1. A voltage Vf correspond ing to the torque value Tf of the meter 101 is obtained with a conditioner amplifier 102. Meanwhile, the torque Tt is detected with a load cell 2. A voltage Vt is obtained with a conditioner amplifier 3. Then, (Vf-Vt) is operated in an adding and subtracting device 103 with respect to the voltage Vf corresponding to the torque value Tf and the voltage Vt. Then, division is performed in a divider 104 using the output value (Vf-Vt) of the adding and subtracting device 103 and the inertia total Wm1 of the dynamometer 1 and a flywheel 14. Then, the rotary angle acceleration omega can be obtained by the expression II (wherein Wm1 is a known value).

Filed: 1986-12-19
Abstract: PURPOSE:To improve the operating efficiency of a device and to facilitate its maintenance by storing disconnection information in a ROM when disconnecting a faulty module from a bus and maintaining this state even after the power source is turned off and on. CONSTITUTION:A function module 3 which performs system constitution control sends a disconnection signal to a common bus coupling part 4 or 5 by using a disconnection signal line 7 or 8 when detecting a fault which can not be recovered occurs to another function module 1 or 2. A coupling part 4 disconnects all signal paths between the common bus 10 and faulty module electrically from the bus 10. The module 3 records the disconnection information in the ROM 9. Even when the power source is turned on again in this state after being disconnected, the module 3 refers to the ROM 9 and disconnects the faulty module from the bus 10. The disconnection state of the faulty module from the common bus is therefore not lost by turning off and on the power source; and the operating efficiency is increased and the maintenance is facilitated.

Title: Window having synthetic resin frame and manufacture thereof
Inventor: SHIGESAWA TOSHIYUKI
IPC: B29C44/16
Filed: 1988-11-30
Abstract: PURPOSE:To eliminate the breakage of a window plate an the damage of an intermediate film by a method wherein an intermediate frame material having a specified fixed cross-sectional shape, which nearly corresponds to a synthetic resin frame consisting of a foaming part under solid or intermediately foamed state and a non-foaming layer, is inserted in a forming mold so as to form the frame by thermally foaming. CONSTITUTION:An intermediate frame material 11 having a nearly same cross-sectional shape as that of a synthetic resin frame 3 is produced. The intermediate frame material 11 is produced by multi-layer extruding foaming part 5a in continuous form, which is made of thermoplastic resin with large dielectric loss mixed with foaming agent under solid or intermediately foamed state and has a certain fixed cross-sectional shape corresponding to a foaming part 5, a non-foaming layer 6a, which is made of the same resin laminating onto the outer surface side corresponding to a non-foaming part 6 as the non-foaming part 6 containing no foaming agent, and an anchoring layer 7a, which has smaller dielectric loss than that of the resin composing the foaming part 5a formed at the joining part of a window plate so as to correspond to an anchoring layer 7. Through the self-heat-generation of the foaming part 5a of the intermediate frame material 11, the integral forming of the synthetic resin frame is performed by the vaporization and expansion of the foaming agent. In this case, since the pressure due to foaming is small, no breakage of the window plate 2 occurs.
