Title: Connecting rod supporting structure for internal combustion engine
Inventor: NOHARA TSUNEYASU
IPC: F16C9/04
Filed: 1992-04-24
Abstract: PURPOSE:To improve the face working by forming a cylindrical radial bearing part and a flange-shaped thrust bearing part on a bearing metal, composing a back surface of the radial bearing part, which is connected to a large end of a connecting rod, of a flat cylinder surface formed concentrically to a rotary shaft and a barrel-like bent surface. CONSTITUTION:A bearing metal 6 is composed of a cylindrical radial bearing part 11 which is connected to an inner surface of a large end of a connecting rod and a flange-shaped thrust bearing part 12 which is projected from an end of the radial bearing part 11. A back surface 13 of the radial bearing part 11 being connected to the inner peripheral surface of the large end of the connecting rod is made up of a flat cylinder surface 14 concentrically spread from a rotary shaft and a barrel-like bent surface 15 continued therefrom. The flat cylinder surface 14 is thus thickened, and a contact area in respect to the inner peripheral surface of the large end of the connecting rod is secured. Therefore, excessive pressure surface is prevented from applying to the connecting rod. Inclination of the connecting rod in front and back directions is eliminated by deformation of the bent cylinder surface 15, so that the pressure surface is prevented from increasing in the vicinity of the end.

Filed: 1992-04-27
Abstract: PURPOSE:To intercept an incoming call to the other terminal by checking the other telephone terminal and returning a response corresponding to a hook-off when the directed sub address and the sub address of the self telephone terminal are dissident. CONSTITUTION:When a call is set to one ISDN line from a telephone terminal 1 at the call originating side, a comparison section 14 compares the sub address of the self station taken out from a sub address register table 17 with the directed sub address. When they are dissident, the call is judged to be from the other station, checking the other telephone terminal to return a response. In this case, a timer 15 is actuated to send 'calling' when no response comes in the lapse of a specified time and to notify an incoming call by ringering. A response is returned corresponding to the hook-off-detection. Then, the reception can be taken place by the other terminal when an incoming call comes to the telephone terminal 1.

Title: Driving method for liquid crystal light quantity modulation element
Inventor: SHIOJI MITSUAKI
IPC: G09G3/18
Filed: 1986-05-09
Abstract: PURPOSE:To always maintain an operation characteristic having high reliability, by always executing an initialization driving before starting an actual driving of a liquid crystal light quantity modulation element. CONSTITUTION:At the time of varying a liquid crystal light quantity modulation element to a real driving state from a stop state or an optional driving state, it is not varied directly as usual, but an initialization driving is executed before starting its real driving. In such way, by always interposing the operation of the initialization driving between the stop state or the optional driving state of the liquid crystal light quantity modulation element and the real driving state, the generation of an abnormal oriented state caused by a disturbance of an orientation of a liquid crystal molecule at the time of variation to the real driving state can be surely suppressed. Also, even if such an abnormal oriented state is generated temporarily in the course of the initialization driving, it is eliminated quickly, therefore, the liquid crystal light quantity modulation element can always be brought to the real driving under a normal liquid crystal oriented state.

CONSTITUTION:When the vehicle overturns and an overturn sensor switch 201 is put ON, a capacitor 205 is discharged through a resistor 203 and when the voltage in a circuit has become lower than a threshold voltage, a comparator 206 outputs an H-output, the reset terminal of a CPU 215 is reset by the L-output of an inverter 214, respective signals of a suel pump, an injector and an igniter are put OFF and the engine is stopped. In this case, if the switch 201 is put OFF again during the discharging time of the capacitor 205, it is regarded as noise and the reset switch will never be put ON. On the other hand, hysteresis due to the resistors 208-210 prevents the re-conversion of the comparator 206 while the CPU is not reset perfectly.
