Title: Collision detecting device
Inventor: KATOU IKUYASU
IPC: B60R21/16
Filed: 1994-10-06
Abstract: PURPOSE: To provide a collision detecting device in which a more precise operation can be expected. CONSTITUTION: This device is formed of a G detecting part 3, a deformation detecting part 2, and a control circuit 19. When the door outer plate 18 of a vehicle is deformed by an impact, the deformation detecting part 2 is ON. On the other hand, when G is generated by the impact, the G detecting part 3 is ON. The control circuit 19 transmits a signal for expanding an air bag when the deformation detecting part 2 and the G detecting part 3 are ON.  In case of the collision of the vehicle, the deformation detecting part 2 and the G detecting part 3 are ON, and the control circuit 19 transmits the signal for expanding the air bag, while the control circuit 19 transmits no signal for expanding the air bag in case of a piece of mischief such as pushing the door by a hand or at the opening and closing of the door since only either one of the deformation detecting part 2 and the G detecting part 3 is ON. Thus, a collision detecting device in which a more precise operation can be expected can be provided.

Abstract: PROBLEM TO BE SOLVED: To form a uniform and highly charged toner layer, and realize high image quality, a small size, and a long life by bringing a sheet-like blade containing a magnetic body into close contact with the surface of a developing roller receiving the attraction force of a magnet inside the developing roller. SOLUTION: In the inside of a hopper 2, a minus charging non-magnetic one component toner 1 is adhered to the surface of a developing roller 3 by a supply roller 6. On the other hand, an iron-made sheet-like blade 5 of 25μm in thickness is deformed along the surface of the developing roller 3 causing closely contact therewith by magnetic force between the blade 5 and a magnet 4 inside the developing roller 3. The toner 1 carried to a contact portion between the developing roller 3 and the blade 5 by the rotation of the developing roller 3 receives pressing force over a long distance from the blade 5 so as to be charged and layer-regulated to form a uniform and highly charged toner layer. Since a nip width is long, the pressing force of the blade 5 can be set small.  Therefore, the deterioration of the toner 1 can be reduced, and simultaneously the adhesion of the toner 1 to the blade 5 can be reduced.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a digital demodulator in which a local oscillation frequency is quickly restored even on the occurrence of out of synchronism in the case when a phase-modulated wave is demodulated. SOLUTION: A phase error detection circuit 19 detects a phase shift between a modulation wave and a local oscillation wave based on an in-phase signal and an orthogonal demodulation signal outputted from a synchronization detection circuit 11. An oscillation frequency of a VCO 18 generating a local oscillation wave with a signal outputted from a loop filter circuit 20 in response to a phase error signal from the phase error detection circuit 19 is controlled. On the occurrence of out of synchronism, and when a level decision circuit 14 detects it that the signal level of the in-phase signal and the orthogonal demodulation signal reaches a prescribed level or below, a signal obtained by dividing an internal clock signal by a prescribed frequency division ratio is given to the loop filter circuit 20.  The time average of the frequency-divided clock signal is a median of a variable range with respect to the input of the loop filter circuit 20, the oscillation frequency of the VCO 18 controlled accordingly is restored to the median of the variable range.
