IPC: B21D24/00
Filed: 1990-03-14
Abstract: PURPOSE:To execute drawing without excessive working and to lead out the scrap from the die by leaving one part of the opening edge of the opening part from cutting, trimming, drawing while pulling the cut left part and leading out a product in a state attaching the scrap of the opening. CONSTITUTION:The blank W is set on the die and the upper die 2 descends. The blank W is roughly formed to the shape of press down die 1. The pad 10 is formed with the slits c. The cutting blade 8 of the upper die 2 is forced into the cutting blade 7 of the lower die 1 and trimming is executed along the trimming line d.

Title: Optical information recording carrier
Inventor: MIURA KYO
IPC: G11B7/24
Filed: 1987-03-18
Abstract: PURPOSE:To prevent writing in an optical recording layer with light for reproduction by interposing a heat transfer layer between a transparent substrate and the recording layer. CONSTITUTION:A heat transfer layer 2 having higher heat conductivity than a transparent substrate 1 having track grooves is formed on the track grooves, an optical recording layer 3 is formed on the layer 2 and a card base 5 is stuck to the layer 3 with an adhesive layer 4. The heat transfer layer 2 having higher heat conductivity than the substrate 1 is required only to cause no trouble during optical information recording and reproduction. For example, the layer 2 hardly causes double refraction and has 1.4-1.6 refractive index nearly equal to that of the substrate 1. The pref. difference in refractive index between the layer 2 and the substrate 1 is <=0.05. Heat accumulated in the optical recording layer during reproduction is radiated and the deterioration of the resulting optical disk or card by light for reproduction can be prevented.

Title: Video signal noise reduction system and noise reduction method using time variable filter coefficient
Inventor: SHIUUREON IU
IPC: G06T5/20
Filed: 1995-03-20
Abstract: PURPOSE:To provide a noise reduction system and a noise reduction method capable of effectively reducing noise even for pictures with large movement. CONSTITUTION:A processed frame memory 70 stores the noise-reduced pictures and a movement estimation device 20 discriminates a target picture element block in the processed frame memory 70. The block is for calculating noise- reduced video signals. A movement compensation noise reduction processor connects the noise-reduced picture element block stored in the processed frame memory 70 with the picture element block at present generated from the video signals and generates a movement block composed of noise-reduced picture elements. Relative weight applied to the stored picture element and the picture element at present is determined by the number of the stored picture elements for generating the picture element. In breakdown detection 60, when the scale of noise reduction achieved for components divided by the scale of the noise in the movement block is larger than a threshold value, the picture elements in the movement block are abandoned.

Title: Automatic answering telephone system
Inventor: TANIGUCHI YUICHI
IPC: H04M1/65
Filed: 1990-03-13
Abstract: PURPOSE:To generate a requirement message having only effective recording by recording again only the effective recording in the requirement message recorded at a 1st recording means by means of a 2nd recording means. CONSTITUTION:A requirement message signal is always monitored by a VOX detection circuit 5 having a detection signal and when a caller finishes the requirement message and the silence state, consecutive tone or intermitted tone is consecutive for a prescribed time (T+alpha) only, an interrupted tone consecutive (VOX) detection circuit 5 detects the end of the requirement message and an ON signal at output terminals 1-4, 1-5 is released, 1st recording is stopped and the line is brought into the incoming call wait state. When the above mentioned detection output is generated from a control circuit 1 having a discrimination means for (T+alpha) time, it is discriminated to be an ineffective tone and 2nd recording is not implemented. When the detection output is generated after the time (T+alpha), it is discriminated to be effective recording and the 2nd recording is implemented. Thus, the message having only the valid recording is generated.

Title: Operating method for reheat steam turbine plant
Inventor: SHINDOU KURA
IPC: F01K13/02
Filed: 1984-03-29
Abstract: PURPOSE:To keep thermal stress in a rotor on a high pressure exhaust stage and the strength of a blade to sufficiently secure levels by effecting opening operation of a steam damping valve placed between a high pressure turbine and a condenser in opposition to that of a steam adjusting valve. CONSTITUTION:Steam supply to a high pressure turbine 35 is interrupted upon starting the turbine and steam from the high pressure turbine 35 is fed to a condenser 45 through a steam damping line 64 whereby the inside of the high pressure turbine 35 is forced to form a vacuum, while reheat steam is supplied to a reheat steam turbine 42 to drive it. Then, when the high pressure turbine 35 is subjected to any load, opening operation of a steam damping valve 63 is effected in opposition to that of a steam adjusting valve 34, and is closed gradually in accordance with opening of the steam adjusting valve 34. Thus, temperature in high pressure exhaust upon starting the turbine can be prevented from being increased as well as thermal stress of a rotor on a high pressure exhaust stage and the strength of a blade can be kept on sufficiently secure levels.
