Title: Cutting method using band saw machine and the same
Inventor: TOKIWA TORU
IPC: B23D55/02
Filed: 1988-09-28
Abstract: PURPOSE:To improve the cutting efficiency and prevent the damage occurring on an upper saw tooth guide and a guide post portion by detecting the height of a work and perform the cutting at the specified feed speed, thereby usually detecting the height of the work during the cutting. CONSTITUTION:When a table 9 or housing is abruptly fed and a work is detected with the first detecting sensors 99, 105, the height of the work is detected by the second work detecting sensor 107. After the work is detected by the first work detecting sensors 99, 105, the table 9 or housing is fed at a specified feed speed to perform the cutting of the work W. In addition, since the height of the work W is usually detected by the second work detecting sensor 107, in the case of the presence of projecting portion on the work W, the height of the projecting portion is detected by the second work detecting sensor 102. By the detection of the height of the projection, it is previously judged whether or not the projecting portion collides with an upper saw tooth guide 41 and a guide portion, thereby stopping the device prior to the collision.

IPC: H01L21/22
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To simulate at a high speed and high accuracy without limiting the travel distance of an Si-oxide film interface and mesh point spacing, by computing the re-distribution of an impurity in a transition region composed of a semiconductor oxide, using diffusion constants peculiar to this region. SOLUTION: A semiconductor is oxidized to produce a new oxide part in one time step. This part is defined as a transition region. Using diffusion consts. peculiar to this region, a diffusion equation is solved to compute the re-distribution of an impurity in this region. This equation provides a model of the impurity transport in the transition region, and hence the transport flux thereof is a diffusion flux defined between adjacent mesh points over all the mesh points contained in this region, thereby realizing a uniform transport of the impurity in the entire transition region.

Abstract: PURPOSE:To improve the transmission efficiency by using a 1st wavelength for an optical signal from a management station to a terminal station, using the 2nd wavelength for an optical signal from a terminal station to the management station and processing a frame of the optical signal sent from the management station. CONSTITUTION:The management station A is provided with an optical transmitter OSA sending an optical signal with a 1st wavelength lambda1 and an optical receiver ORA receiving an optical signal of the 2nd wavelength lambda2. Terminal stations B-D are provided respectively with optical branching confluence devices OTB- OTD coupled with an optical loop bus OB, optical receivers ORB-ORD and optical transmitters OSB-OSD. Through the constitution above, an optical request signal from the station A to the stations B-D uses the wavelength lambda1 and the optical reply signal from the stations B-D to the station A uses the wavelength lambda2. Thus, even when the bus OB is used in common, both the signals can be identified. Moreover, the station A processes the optical request signal as a frame and sends the optical reply signal for a definite period assigned to the stations B-D by a prescribed time each in each frame. Thus, no guard time is required and the transmission efficiency is improved.

Filed: 1988-09-27
Abstract: PURPOSE:To obtain a low-cost colored sintered material having high strength and high toughness free from color shading by blending ZrO2 powder with CeO2 powder to give an intermediate mixture, adding Cr2O3 powder to the mixture, grinding, molding and calcining. CONSTITUTION:Powder consisting of 2-16mol% CeO2 powder and the rest of ZrO2 powder as main components or consisting essentially of ZrO2 powder is blended to give an intermediate mixture. Then 75-98wt.% of the intermediate mixture is blended with 2-25wt.% Cr2O3 powder, ground, molded and calcined to give the aimed sintered colored zirconia ceramic. When content of CeO2 in the intermediate mixture is <2mol%, zirconia crystal of tetragonal system is unstable and strength of sintered zirconia ceramic of monoclinic system is extremely reduced during cooling process after sintering. When the content of CeO2 exceeds 16mol%, content of zirconia crystal of cubic system is increased and strength of the sintered colored zirconia ceramic is reduced.

Title: Semiconductor memory element
Inventor: KAJI NAOTO
IPC: G01R31/28
Filed: 1988-09-27
Abstract: PURPOSE:To easily test performance at the time of reading-out by providing a clock input to be used only at the time of the function test of an element independently from a clock being usually used. CONSTITUTION:A line 106 is made into value '1' at the time of a testing and a selector 7 sends out the clock for the testing to be inputted from a line 105 to a reading-out data register 4. It is similar to an ordinary time that an address is inputted from a line 101 and read out from a line 112, however heading-out data are set in the reading-out data register 4 by the clock for the testing being inputted from the line 105. Since the clock to set the address and the clock to set the reading-out data are independent, an arbitrary value can be set by making independent a time from setting the address till setting the reading-out data from the clock cycle at the time of writing. Thus, the capability of the reading-out time can be easily tested.

Abstract: PURPOSE:To satisfactorily execute transfer and separation with regard to all modes by changing a control current of a transfer pole and a separation pole in accordance with the time of a high speed and low speed and the tie of the reverse side and the surface. CONSTITUTION:A photosensitive drum 11 rotates at a peripheral speed of two stages or three stages by selecting the magnification of variable power. To a transfer pole 14 which is shielded by a shielding member 21, a DC voltage of plus corresponding to a line speed of transfer paper is applied through a high voltage transformer which is brought to constant-current control. Also, to separation wires 15a, 15b of a separation pole 15, an AC voltage on which a DC bias brought to constant-current control is superposed is applied in accordance with line speed. Moreover, at the time of reverse side copying, a DC bias voltage of the separation pole 15 is made different from that voltage at the time of surface side copying. In such a way, in case of both one face and double face copy, a transfer and a separation can always be executed satisfactorily.
