Title: Dry etching
Inventor: SAGAWA SEIJI
IPC: H01L21/302
Filed: 1986-12-23
Abstract: PURPOSE:To suppress a side etching amount from a mask, by electrostatically attracting a wafer to cool it when a lower layer organic film is subjected to dry etching, and specifying its surface temperature. CONSTITUTION:A DC bias 6 is applied to the lower electrode 3 of a parallel flat plate type reactive ion etching unit A to electrostatically attract a wafer 1, thereby enhancing cooling effect with coolants 4, 5. The lower layer resist of the wafer 1 is formed of a phenol resin positive resist film, an intermediate layer is formed of an SOG film, and an upper layer is formed of a positive resist film. Then, with the upper layer resist as a mask the SOG is subjected to dry etching. Thereafter, with the upper layer resist and the intermediate layer SOG as masks the temperature of the wafer 1 surface is held by electrostatic attraction at 20 deg.C or lower by the unit A to anisotropically etch a lower layer resist with O2 gas. Thus, a side etching amount from the mask can be suppressed.

Title: Image transmission method and image transmitter
Inventor: HIRATA SHINICHI
IPC: H04N19/00
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent the effects of other images of transmission errors and to switch and display the images at a sure timing by adding the identifier of the image and the identifier of a minimum coding unit(MCU) to a transmission unit, performing transmission and decoding coded data and substitutive data, when the image identifier of received data is changed on a reception side. SOLUTION: Normal coded data from an image coding means are stored worth one screen, the coded data of the MCU are segmented from there as the transmission unit, an image ID and an MCUID are added in front of the coded data, and they are outputted to a communication control means as transmission data. After an image transmission control means outputs the coded data of the final MCU of the final image, data to which the image ID=99, for example of a dummy for reporting transmission end to the reception side p set are transmitted. At that time, a communication control procedure detects an error as the transmission data for one unit. Thus, even when the plural images are continuously transmitted, the generated transmission error is prevented from affecting other screens.

This rib 6b and bottom part 1a are fixed together by means of an adhesive such as anchor bond 7 or a fixing agent. These rib configurations can be obtained by a punching work process or heating molding, after molding a battery jar made of resin. In this way, the vibration-proofing property of a tightly closed type lead acid battery can be remarkably improved not only in longitudinal and lateral directions but also in vertical direction.

Filed: 1988-12-16
Abstract: PURPOSE: To attain the dynamic establishment of a transmission group number between a pair of nodes by transmitting an exchange identification message from each node to a remote node at the time of initializing connection between arbitrary two nodes. CONSTITUTION: In a communication network 10 constituted of nodes 12, 14, and 16 and links 18, 20, and 22 or the like, each node transmits an exchange identification message to a remote node at the time of initializing connection. A non-zero transmission group number (TG#) and a zero TG# are included according to the presence or absence of the definition of the non-zero (TG#) in the previous time. Next, the TG# included in the message from the remote node is decided, and when the different TG# are transmitted from a pair of nodes, the non-zero TG# is selected. Then, when both zero TG# or non-zero TG# are transmitted from the pair of nodes, the significance of a node name is compared according to a prescribed reference, the node having the more significant name is selected, and the final TG# is assigned. Thus, the transmission group number can be dynamically established between a pair of nodes.

This neck part 2c is formed at an inclination angle theta to a drum part wall and bent sharply from the drum part wall. When the inner bottle into which rice and boiling water are put is inclined, boiling water is discharged together with sliminess of rice and only rice is left behind between the bent neck part and the upper end of the drum part. Since the orifice of the inner bottle 2 is smaller than the diameter of the drum part 2b, the insulating effect larger than a conventional inner bottle whose diameter of the neck is the same as that of the drum part is secured.

Title: Optical head with isolator for coupling semiconductor laser to photoconductor
Inventor: EMANIYUERU GURAARU
IPC: G02F1/09
Filed: 1989-12-07
Abstract: PURPOSE: To facilitate the production and adjustment of an optical head into which an isolator is built by providing the optical head with a polarization guide consisting of a light guiding body of a certain length connected to the light guiding body to which a polarizer is to be coupled. CONSTITUTION: A rotary crystal 4 and a magnet 6 constitute a rotating device consisting of a Faraday rotator. The axial line direction hole 7 of the magnet extends along the longitudinal direction. The crystal is fixed to face a laser 2 in the rear part of a sleeve 5 arranged in the hole 7 and a condenser lens 8 is fixed to face a polarization fiber 10 in the front part of the sleeve. When the polarized light passes the rotating device, the plane of polarization rotates 45 deg. and the image of a laser spot is formed on the inlet surface of the polarization fiber 10 via a lens 8. The light reflected at the first connector or line end is polarized by passing the polarization fiber. When the light passes the Faraday rotator, the plane of polarization thereof rotates 45 deg. and the light is returned to the laser by a TM mode.  The smaller number of the optical members is thus necessitated.
