Title: Television receiver
IPC: H04N5/445
Filed: 1992-03-18
Abstract: PURPOSE:To determine a vertical display position so that display contents of horizontal synchronization to be pulles up are equal to those of horizontal synchronization of an odd field to be superposed on them. CONSTITUTION:Even field and odd fields of a video signal are discriminated by an even/odd discriminating circuit 12. When an even field is discriminated, 1/2H vertical synchronizing signals of a picture display circuit 2 and a teletext decoding circuit 1 are delayed, and a switch circuit 5 is switched by blanking signals from the picture display circuit 2 and the teletext decoding circuit 1 to select R, G, and B signals outputted from the picture display circuit 2 and the teletext decoding circuit 1, and they are applied to a display screen 10. When the even field is discriminated by the odd/even discriminating circuit 12, a vertical deflecting coil 7 is excited to determine the vertical display positions of the teletext signal and the picture display signal. Thus, visual jitter is eliminated at the time of non-interlating of relations between the vertical display position in an even field and that in an odd field.

Title: Liquid jet recorder
Inventor: SUGIYAMA HIROSHI
IPC: B41J2/175
Filed: 1986-03-20
Abstract: PURPOSE:To enable high-precision and high-quality recording to be performed with a large recording medium by causing a recording head and a recording liquid to be moved by individual drive means. CONSTITUTION:A mobile stand 13 mounted with a recording liquid tank 12 and a carriage 3 equipped with a recording head 1 are supported independently of each other on a guide member 5. When the carriage 3 is driven by a motor 7, the recording head 1 is caused to perform an accurate scan so that high- quality recording may be achieved. In this case, high-precision accurate movement speed in required. However, high precision is not badly required for the drive of the mobile stand 13 using a motor 17. Accordingly the mobile stand 13 has only to be moved so that the carriage 3 and mobile stand 13 may not contact with each other or an excessive stress may not generate on a liquid conduit pipe 14. a flexible pipe is used as the metallic liquid conduit pipe 14. Thus, the shift between the movements of the carriage 3 and mobile stand 13 will not be influenced by the state of their connection.

Title: Main storage access system
Inventor: MORI YOSHIICHI
IPC: G06F9/52
Filed: 1987-03-18
Abstract: PURPOSE:To prevent contention in a lock area access by executing the access of a specified area of a main storage device being a lock area after collating the lock control bits of other CPUs by the processes of respective CPUs executing access and checking the contention state to other CPUs. CONSTITUTION:Respective CPUs set the control bits of themselves to a logical '1', and announce that it is the access of the lock area with respect to other CPUs prior to the access of the main storage device MS. The CPUs test the lock control bits for adjusting the contention with other CPUs so as to attain synchronization. Namely, the test of the lock control bit state of other CPUs is waited until the lock control bit state of oneself is reflected with respect to all the other CPUs. When the lock control bits of other CPUs are all logical '0' (XLOCK='0') as the result of the test, the access of the storage device MS is proceeded.

Abstract: PROBLEM TO BE SOLVED: To discriminate whether the cause for unfilling and nesting defect of resin is due to an abnormal resin characteristic or an equipment trouble and then automatically control the equipment accurately, according to the cause for the trouble by monitoring the force applied to a plunger, with the force being classified into injection resistance force and sliding resistance force. SOLUTION: A plunger is raised without resin residue left over in a pot and a sliding threshold is found from an initial value of sliding resistance force obtained from a load cell 3 at the raising of the plunger, and the sliding threshold is set in an analyzing section 41. Next, an injection threshold is found from an initial value of injection resistance force obtained from the load cell 3 at the pressurizing of the melted resin in the pot by the plunger and the injection threshold is set in the analyzing section 41. After that, the melted resin in the pot 1 is pressurized by the plunger 2 for resin molding, and when injection resistance force obtained from the load cell 3 extends the injection threshold, the resin is determined as being abnormal, then the equipment is stopped, and the resin abnormality is displayed.  When sliding resistance force obtained from the load cell 3 at the raising of the plunger 2 with the pot 1 which is vacant exceeds the sliding threshold, a controller automatically conducts a cleaning operation for eliminating the resin residue.

Abstract: PURPOSE:To manufacture a pressure transmitter at low cost by dividing a rod into a base and a tip part, and using the same materials as a beam and a pressure reception part for the base part and tip part while they are equalized in length respectively, and making the both almost equal in thickness. CONSTITUTION:The conventional rod is divided into two, i.e. base part and tip part, and the pressure receiving plate 2 and beam 1 are nearly equalized in length to and use the same materials with said base and tip parts; and said base part and tip part are welded to manufactured the rod 10.
