IPC: B65B7/28
Filed: 1987-12-29
Abstract: PURPOSE:To make it possible to seal independently only a heating vessel without necessity to process together with vessels in which food stuffs are contained, by pushing to closely seal a vertical wall of a lid and a side wall of the vessel into a ring groove of a holding member by a forming roll. CONSTITUTION:A press rod 13 descends along a guide member 11. Then, a contracted diameter part 13a departs from a roller 17 and the outer face above the cam contacts the roller 17. Thereby an arm 15 rotates outside on an axis 16 against a spring 23. At the same time, a protrusive flange (18a) at the bottom end of a forming roll 18 pushes the vertical wall 31b of a lid 31 and the side wall of a vessel 30 into the receiving groove 2a of a holding member 2. When turning a rotary disc 20a keeping the above state, three forming rolls 18 rotate around the center axis C with rotation on its own axis and the protrusive flange 18a of the forming roll rotates by one circle or several, pushing the vertical wall 31b of the lid and the side wall of the vessel 30 along the receiving groove 2a of the holding member 2. As a result, the vertical wall 31b of the lid 31 and the side wall of the vessel 30 protrudes to be a ring and to be securely jointed with each other.

Title: On-vehicle acoustic device
Inventor: MOTOJIMA AKIRA
IPC: H03G3/32
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To eliminate the anxiety caused by the reproduced sound of acoustic sources of other seats by providing a masking means which outputs noise from a speaker. SOLUTION: The switch which selects acoustic sources, is provided for every seat. If the performance of a CD is selected in a seat A and no musical performance is reproduced in a seat B, a speaker 5 outputs the reproduction of the CD because a CD reproducing is selected by a switch 3 in the seat A. Therefore, the CD reproduction sound from the speaker 5 leaks to the seat B. Since no musical performance is reproduced in the seat B, a selection switch 6 selects a microphone 1. Thus, the vehicular running noise collected by the microphone 1 is amplified by an amplifier 7 and reproduced by a speaker 8 of the seat B. As a result, the reproduced sound of the CD from the speaker 5 of the seat A is masked by the vehicular running noise from the speaker 8 and the sound from the seat A does not trouble the passenger in the seat B.

Abstract: PURPOSE:To improve responsibility without lowering responsibility by separating a transmitting path to a digital system, which deals with digital data only, and an analog system, which deals with analog quantity data only, in the transmitting path to equip a signal transmitting bus which connected a master station and plural slave stations mutually. CONSTITUTION:A digital system transmitting path 3a is provided to deal with only binary data such as the presence and absence of a condition, etc., and an analog system transmitting path 3b is also provided to deal with only the data concerning the volume of a current value and a voltage value, etc. For the both transmitting pathes 3a and 3b, digital bit data are transmitted in the transmitting path. By the separation of the digital system 3a and the analog system 3b, the loads on the respective transmitting paths 3a and 3b are reduced. Especially, in the digital system to deal with the control signal of a small bit number and to be requested a high responding speed, boring signals 7a-7c are successively transmitted. Accordingly, since data length is short, a cyclic time for a data processor 11 to receive slave station responding signals 8a-8b can be widely shortened. Then, the responding speed can be widely improved.

Title: Liquid crystal display device
Inventor: KAWAMURA NOBUYUKI
IPC: H04N5/66
Filed: 1992-12-15
Abstract: PURPOSE:To change error DC voltage due to a difference between command voltage and offset voltage and to prevent a liquid crystal panel from being deteriorated by changing the driving voltage of the panel in a specific saturation voltage or a specific scanning period. CONSTITUTION:After amplifying an input signal, a saturated voltage changing circuit 6 changes signal amplitude more than a specific saturation voltage in each prescribed time out of an output signal whose voltage/transmissivity characteristic is corrected by a gamma correction circuit 3. A horizontal synchronizing inverse driving circuit 4 inverts the polarity of the corrected video signal in each horizontal period and inputs the inverted signal to the liquid crystal panel 5. Since the driving voltage of the panel 5 is changed with the lapse of time and an error DC voltage due to a difference between the common voltage and the offset voltage is changed, the impression of a fixed voltage to the panel 5 for a long time can be removed and the panel 5 can be prevented from being deteriorated.
