Filed: 1993-12-27
Abstract: PURPOSE:To prevent bone fixing power from being lost by infection of ambient tissues with bacteria and to obviate generation of excessive bone absorption by impartation of damage more than necessary on the bone by composing an artificial dental root of an intermediate member and an abutment member and forming the surface of this intermediate member of a material-free from a vital injuring property and bone fusion property. CONSTITUTION:A fixture 1 of the artificial dental root has preferably a bone fusible surface in order to be implanted and fixed into the alveolar bone. The intermediate member 2 is freely attachable and detachable to and from the top end side of the fixture 1 and is implanted together with the fixture 1 for the specified period of time into the alveolar bone. The abutment member 3 is fixed to the top end side of the fixture 1 in place of the intermediate member 2 and its front end part projects into the oral cavity. The upper structure by an artifact, such as artificial crown, is fixed by the front end of the abutment member's. The intermediate member 2 is composed of the material which is free from the vital injuring property and bone fusing property in at least the surface in contact with the bone or its surface is treated to a mirror finished surface state so as to have the non-bone fusible outside surface in the case the member is composed of a metallic material having the bone fusing property.

Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device excellent in the stock property of ejected transfer paper and capable of being installed in restricted space. SOLUTION: The width of the vertical part 42a of an image forming part 30 is set so that the leading edge of the using feasible maximum-sized transfer material ejected in an paper ejection space falls within a main body width range and a supporting member 43 consisting of sheet metal for connecting the image forming part 30 and an image read part 20 is arranged at the downstream-side end part of the paper ejection space 50. Thus, since the transfer material ejected to the space 50 is not protruded from a main body because the leading edge thereof is properly regulated by the sheet metal 43, the storing property of the ejected transfer material is drastically enhanced. Besides, the image forming device can be installed if there is the space as much as the main body width.

Filed: 1987-12-28
Abstract: PURPOSE:To improve the tracking performance of a tuning voltage by supplying a voltage higher or lower than a tuning voltage of each channel by a prescribed value to a tuner section for a prescribed initial time of a sweep period of each channel. CONSTITUTION:When a setting voltage corresponding to each tuning voltage of,e.g., one or three channels synchronously with the sweep period of a sweep generator is outputted from a signal output port A of a control section 6 in a waveform adjusting device, the signal is converted into an analog signal by a D/A converter 2 and an operational amplifier 3 and the voltage is decreased by a prescribed voltage by a voltage shift circuit 7. When the tuning voltage is decreased to a negative voltage for a prescribed time, the output signal of the control section 6 is boosted in advance by a prescribed voltage taking the required negative voltage as the positive voltage to operate a converter 2. Then the voltage is dropped by a prescribed voltage boosted by the circuit 7 and the tuning voltage of a specific channel is pulled in the negative voltage to output a tuning voltage corresponding to each channel.

Title: Serial transistor circuit
Inventor: SATO HITOSHI
IPC: H03K17/10
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent the voltage higher than a rated level from being applied to every transistor TR by connecting a diode to each base side of serial TR group to clip the applied voltage by the reverse characteristic and to control the collector current by the forward characteristic and then inputting a control signal to the base of a low potential of the serial TR group. SOLUTION: The clipping diodes 21a to 21d are connected to the bases of TR 10a to 10d which are connected in series via the base resistances 20a to 20d respectively. The diodes 21a to 21d consist of the avalanche diodes, i.e., the elements which have the constant voltage characteristic in the reverse direction and also positively flow the currents in the forward direction. Therefore, the TR 10a to 10d are simultaneously turned on/off and the voltage of a high voltage terminal 13 is outputted/cut off to/from a low voltage terminal 16 when the voltage is applied/deleted to/from a control terminal 17. Thus, it's possible to keep the voltage applied to every TR at the value lower than a rated level with a simple circuit constitution.
