Abstract: PURPOSE:To form a sliding surface having high resistance to corrosion and abrasion on a steel material, by subjecting the steel material to a surface hardening treatment such as chill hardening, melt spraying, padding, induction quenching, carburization hardening or the like then subjecting the hardened surface to a nitriding treatment and an oxide film treatment. CONSTITUTION:Parts consisting of ordinary cast iron such as cam shafts of the cylinder head of a 4-cycle engine or the like are chilled to about 40-50 deg. HRC chill hardness, whereafter the parts are subjected to stress relieving annealing for about 1-3hr at about 600-630 deg.C and further to finishing. The parts are held for about 40-180min at about 580-610 deg.C treatment temp. and are subjected to a soft nitriding treatment such as a tufftriding treatment. The parts are then cooled in a hot bath of about 350-500 deg.C by using an intermediate cooling salt bath and are held for about 10-30min to apply an oxide film treatment; thereafter, the parts are cooled by air and water. The treated surface which is free from generation of crack, rusting, etc. and lessened wear is thus obtd.

Title: Driving method for on-demand type ink jet head
Inventor: HANAOKA SEIJI
IPC: B41J2/045
Filed: 1980-08-25
Abstract: PURPOSE:To enable to obtain a predetermined jetting velocity for a droplet with a lower driving voltage by positively utilizing the damped vibration of a vibration system which consists of the walls of a pressure chamber, an electromechanical transducing means and an ink. CONSTITUTION:A piezoelectric element 9 expands in radial directions to lift up the wall 5 when charging is started. At this time, the ink 6 is sucked in through a supply port 4, while air is sucked in through an opening 3a. When the charge accumulated in the piezoelectric element 9 is instantaneously discharged around the time the sucked-in amount 20 of air reaches a maximum, the wall 5 and the element 9 are returned to their original positions due to the elastic energy accumulated in them, so that the ink 6 sucked into the pressure chamber 2 is discharged into the air as the droplet 21. The wall 5 and the piezoelectric element 9 performs damped vibrations after the charging is started, the timing of the maximum of the damped vibration being substantially coincident with the timing of the maximum sucking-in of air.

Title: Motion image data transmission method and transmitter
Inventor: SHINODA MAYUMI
IPC: H04N21/6377
Filed: 1994-05-30
Abstract: PURPOSE:To minimize deterioration in image quality without deteriorating a transmission efficiency by transmitting again data of an erroneous part only when a detected error gives adverse effect on a wide range of the image quality and avoiding re-transmission when the error does not affect on a wide range. CONSTITUTION:An error detector 207 checks and corrects errors of a signal received by a receiver 206 for each data block. A data block from which no error is detected passes through a re-transmission buffering device 210 without any processing and decoded by an image decoder 211. When an error unable to be corrected is detected, a picture discrimination device 208 uses the decoder 211 to discriminate a type of a picture being decoded at present (any of I, P and B pictures). When the picture is an I picture or a P picture, a re- transmission request transmitter 209 transmits a re-transmission request of an erroneous data block to a transmitter side. Then header information is transmitted prior to actual image data at first and decoded by the decoder 211.

Title: Waveform observing device with function of successively displaying x-y combined waveform
Inventor: MACHIDA MASANOBU
IPC: G01D9/00
Filed: 1991-04-19
Abstract: PURPOSE:To observe an X-Y combined waveform in detail and obtain fair judgment on the waveform by successively displaying the waveform one part by one part by appropriately operating a key. CONSTITUTION:By operating an operation key 70 for successive display, the number of X-Y combined waveform data corresponding to the operated state of the key 70 is decided 78. Therefore, when a starting address for preparing the first X-Y combined waveform data is decided 82, an X-Y combined waveform data displaying means 40 prepares X-Y combined waveform data by successively reading out paired X-and Y-axis waveform data from a memory and displays the prepared data after performing vector-processing on the data. Then whether or not all data have been prepared is discriminated 80 and, when the preparation is not completed, the next starting address is decided 82 by adding the starting address and the number of data decided 82 and 78 immediately before by again operating the key 70. Then, similarly, waveform data are read out from the memory and vector-processed data are displayed 40. Thus a resultant waveform can be appropriately displayed by successively displaying the waveform one part by one part by repeatedly operating the key 70.

Title: Video signal shaping method
Inventor: FUKUSHIMA YASUMASA
IPC: H04N5/91
Filed: 1982-07-05
Abstract: PURPOSE:To prevent the generation of buzz, by providing a video signal level varying means to a path of a video signal for eliminating noise without giving distortion to the video signal. CONSTITUTION:When a normal part of the video signal is outputted from a video amplifier circuit 11 in a special reproducing mode, since a clip level of a clip circuit 13 is high, the video signal is inputted to a video output circuit 12 without being subject to distortion. On the other hand, when a noise of the video signal is outputted from a video amplifier circuit 11, the clip level is low and the noise is clipped effectively. Thus, the noice level is decreased to a white level of the video signal or below in the video signal D outputted from the video output circuit 12. Thus, the noise is eliminated without giving distortion to the video signal in this way, allowing to prevent the generation of buzz.
