Title: Air conditioner
Inventor: OZEKI SHIGEKI
IPC: F25B13/00
Filed: 1993-01-28
Abstract: PURPOSE:To provide an air conditioner in which heat dissipation to the outside of a system is prevented and a heating capability is prevented from being lowered by providing a parallel circuit of a check valve and a heating expansion mechanism on the back-stream side of an outlet side assembly pipe of an outdoor heat exchanger and further providing a heat exchanger on the back-stream side of the parallel circuit in which exchanger a refrigerant in the parallel circuit and a refrigerant passing through the heating expansion mechanism are rendered to heat exchange. CONSTITUTION:An expansion mechanism 15 is provided parallely to a check valve 16 disposed on the side of a fluid outlet of an outdoor heat exchanger 19, and a heat exchanger 14 is provided on the downstream side of the expansion mechanism 15 such that a refrigerant in the parallel circuit and a low pressure refrigerant passing through the expansion mechanism 15 are heat exchangeable. Upon heating, a high pressure refrigerant partly containing a gas refrigerant enters the heat exchanger 14 after passage through a piping 13 and heat- exchanges with the low temperature low pressure refrigerant reduced in the pressure through the expansion mechanism 15 to become a subcooled fluid which fluid in turn enters the expansion mechanism 15 and is reduced in the pressure to become a low temperature low pressure refrigerant and thereafter enters the heat exchanger 14. The low temperature low pressure refrigerant absorbs heat from the refrigerant flowing through the piping 13 and enters a distributor 17. Thus, the refrigerant is prevehted from being heat dissipated to outdoor air and hence a heating capability is prevented from being lowered.

IPC: B66C13/54
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To reduce time for transportation and assembly and the number of processes, reduce costs with a less number of components and avoid problems with erroneous assembly of a hydraulic hose and an electric harness, pressure loss or poor connection. SOLUTION: An opening 18 or an openable portion is provided throughout the vertical length of a supporting frame 9 of a cab. In the trailer transportation of a construction machine, the supporting frame 9 is disconnected from the cab and a revolving structure is disconnected from the cab.

Title: Magnetic recording/reproducing device
Inventor: HIRATA KENICHI
IPC: G11B5/027
Filed: 1989-01-19
Abstract: PURPOSE:To automatically realize the optimal recording state of plural heads executing multi-layer recording by detecting the level of respective recorded signals in a recording-temporarily-stopping mode, and controlling the gain of respective recording amplifiers so that the detected level may be the initially set level. CONSTITUTION:When a command to temporarily stop the recording (REC PAUSE) is issued, a magnetic tape 50 is rewound for 33 control buses, and it is made into a temporarily stopped state. Further when the mode shifts to a recording starting mode, the tape is made into a phase matching/reproducing state approximately for one second, it is synchronized with a control signal recorded beforehand, and made into a picture recording mode. In a constant time when the recording is started after the temporarily stop of the recording, the level of the regenerative signals of the respective recorded heads is detected, the difference between an initial value is comparatively operated, and the respective head recording levels are automatically corrected to the optimal value. Thus optimal performance can be realized without any regulation.

Title: Coordinate input device
Inventor: ANO TADASHI
IPC: G06F3/0354
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To improve the operability of an input pad emulating the operation of the scroll of a window screen through a scroll bar in an active window on a display device. SOLUTION: First scroll area 4a, and 6a and second scroll areas 4b, 5 and 6b are provided in an input operation face 7. When a finger touches the first scroll area 4a, vertical scroll corresponding to the movement of a coordinate of the finger in the area 4a is executed. When the finger slides to the second scroll area 4b from the area 4a, a scroll mode is switched and scroll corresponding to the indication time of the area 4b is continued. The direction of the scroll of the second scroll areas 4b, 5 and 6b is set to be the direction when the finger moves from the area 4a and 6a. Thus, two scroll directions can be allocated to the area 5. Since consistency exists between the movement of the finger and the direction of scroll, scroll operability is improved.

Title: Drive circuit in impact wire dot head
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J2/30
Filed: 1990-01-23
Abstract: PURPOSE:To inhibit the occurrence of an adverse current by a method wherein when a common wire drive switch is in ON states, an induction current flow path change-over switch is in OFF state, and when the common wire drive switch is in OFF state, the induction current flow path change-over switch is in ON state. CONSTITUTION:In a cycle T2, a drive coil 11 is driven, that has not been driven in a cycle T1 and is commonly connected to a drive coil 10. Firstly, a common wire drive PNP transistor 1 and a discrete drive NPN transistor 5 are turned ON. Thereafter, the drive coil 11 is driven under control of a drive signal similarly to the drive coil 10. In a period Ta2 in the cycle T2, the OFF state of an induction current flow path change-over PNP transistor 2 prevents the forming of a circuit loop (n) containing the drive coil through the drive coil 10, a discrete diode 6, the induction current flow path change-over transistor 2, and the common wire drive transistor 1 as shown by a two-dot chain line. Thus, a ring current of an adverse current caused by a power generation action of a residual magnetic flux phi1 is inhibited.

Abstract: PURPOSE: To make it possible to operate continuously a generator even when an abnormal speed signal is generated during parallel operation with a power system. CONSTITUTION: When a speed detector at a rotational position of a generator breaks down and an abnormal rotation speed (FT) is out of order, a switching unit 11 changes an opening control signal (GS) to an reactive control signal (GX) on the basis of a failure signal (F) generated from a failure detecting unit 10. Then, a lower-value selecting unit 8 selects a load limiting signal (GL) and generates it as an opening command signal (GR) so that a guide vane is controlled. As a result, the generator can be operated continuously.
