Title: Fixed cylinder for video tape recorder
Inventor: KOJIMA TAIZOU
IPC: G11B15/61
Filed: 1983-03-02
Abstract: PURPOSE:To keep an air film formed by the rotation of a rotary cylinder constant in thickness and to improve picture quality by forming an air film pressure control part around a fixed cylinder along the end part of the rotary cylinder on the side of the fixed cylinder. CONSTITUTION:A groove 5 as the air film pressure control part is formed in the guide surface 6 of the fixed cylinder 6. The groove 5 is provided along the end part on the side of the rotary cylinder 1, and the groove is deep at the entrance side of a tape run and shallow at the exit side while constant in width. The air film is formed by the run of the magnetic tape 3 and the high-speed rotation of the rotary cylinder 1, but a pressure drop of the air film is large at the tape entrance side because of the groove 5, so the thickness of the air film is reduced and becomes constant in the lengthwise direction of the magnetic tape 3. Specially, the groove 5 is close to where a head chip 2 is passed, so a decrease in the thickness of the air film is remarkable at this part and the tape 3 and head chip 2 contact each other more stably.

Abstract: PURPOSE: To prevent the lack of fusion near the start of welding and improve welding strength by performing preceding welding for a short time by reverse polarity arc at the start of welding in performing positive polarity arc welding of the superposed end parts of thin steel sheets.  
     CONSTITUTION: At the start of welding, a controller 24 turns on only the power source 20 for starting and generates the reverse polarity arc between a welding wire 16 and both steel sheets 10, 12. After lapse of a predetermined time, the controller 24 turns off the power source 20 and turns on a power source 22 for generating positive polarity arc, thereby generating the positive polarity arc between the wire 16 and both sheets 10, 12. When the predetermied welding by the positive polarity ends, the controller 24 turns off the power source 22, thereby ending the welding.

Title: Intermittent reception system
Inventor: FURUNO TATSUO
IPC: H04W88/02
Filed: 1987-02-20
Abstract: PURPOSE:To contrive the reduction of control channel occupancy time by detecting the period of a notice signal from each radio telephone set to a radio telephone set and setting the intermittent reception mode via a radio connection device in response to the period. CONSTITUTION:While using a clock 38 so as to count the time, the occurrence of frequency of traffic is taken into account, a radio line controller 32 brings a transmission period of location information informed via radio connectors 34a, 34b to all radio telephone sets in the system into a period corresponding to the intermittent reception mode desired to be set. The period of the information signal transmission corresponding to each intermittent reception mode is not an integer multiple of other period to avoid the malfunction. That is, at a daytime when lots of traffics exist, the radio line controller 32 sends a notice signal at a period corresponding to the normal mode via the radio connectors 34a, 34b to all the radio telephone sets in the system for the intermittent reception of the normal mode to allow all the radio telephone sets to apply the intermittent reception of the normal mode. Thus, the control channel occupancy time required for the call of the radio telephone set is reduced.

Title: Line switching system
Inventor: MITSUISHI KAZUYUKI
Filed: 1987-02-19
Abstract: PURPOSE:To improve the reliability in a star type line network by duplicating a repeater and using a low-order port of a repeater on standby as an extension port. CONSTITUTION:Setting switches S1a, S1b so as to connect incoming lines 50a, 50b on the standby state which are connected to the high-order node to collision detection sections 20a, 20b of a repeater to be connected, the line from the low-order ports 12a, 12b of the repeater in the standby state is concentrated to detect the collision of frames. Since collision detection sections 20a, 20b detect collision from the state change of each line, frames ORed by a repeater cannot be detected whether or not the frames are in the collision state, and the collision detection signals are ORed. Since a signal from the host device is distributed as it is in the outgoing lines 52a, 52b, they are connected directly. In order to constitute the connection, the repeaters are connected by connectors 21a, 21b and the repeater is switched by a line with the high-order node and the low-order ports 12a, 12b are used as extended low-order ports and the duplication of the part except collision detection sections 20a, 20b is constituted.

Title: Surface acoustic wave device
Inventor: YAMADA JIYUN
IPC: H03H9/02
Filed: 1982-03-10
Abstract: PURPOSE:To improve the radiation admittance without generating reflecting waves in electrodes, by taking at least one electrode width (l) of a reed screen electrode as 0.5lambda>l>=0.495lambda (where lambda is wavelength of surface acoustic wave). CONSTITUTION:Electrode reflection waves in one wavelength are four kinds, (a)-(d). Since the relation between the (a), (b) and (c), (d) is only different from the phase by 2pi, it is enough to consider the relation between (a) and (b) only. The phase theta of the reflecting wave of (b) is 4pil/lambda-pi, taking the reflecting wave of (a). Thus, the synthesized reflecting wave is 1+ej . The reflecting wave level with the electrode width lambda/4 is maximum 0 and smaller as the electrode width closes to lambda/2, and the level is -30dB at the electrode width >=0.05 and between 0.495lambda and 0.5lambda. The latter is adopted out of said ranges for the purpose of increasing the radiation conductance. That is, the electrode width is brought the vicinity of lambda/2 suffciently, allowing to increase the radiation conductance and to prevent the generation of the reflection in the electrode.

Abstract: PURPOSE:To perform continuous combustion for a long time without needing hands, by a method wherein solid fuel is fed, in order, into a combustion furnace, and operation of the vibrating mechanism of the combustion furnace normally shakes off combustion ash which is an obstacle to combustion. CONSTITUTION:In a combustion part 2, combustion ash (b), produced after combustion, is vibrated by retainer bodies 17, 17, and a part thereof is discharged to the outside through a gap 14 between small plate bodies 16 attached to each of the retainer bodies 17, 17. The remaining ash is vertically dropped, and all the ash is collected in a containing box 29 through rooster 11. Meanwhile, solid fuel (a) before combustion, present on the upper surface of a support plate 10, is dropped, in order, in a combustion furnace 12 through spacings 13 on both sides of the supporting plate 10 as the solid fuel (a) in the combustion furnace 12 is exhausted. However, since the supporting plate 10 is heated to high temperature, the fuel is heated thereby, and when is is admitted in the combustion furnace 12, it is conditioned to be apt to burn, resulting in easy complete combustion.
