Title: Electrostatic recording head
Inventor: TOUDOU YOSHIMASA
IPC: G03G15/05
Filed: 1983-01-20
Abstract: PURPOSE:To make it possible to prevent the lowering in recording density by suppressing the surface change of a recording electrode, by coating the part of the head surface of a multi-needle recording electrode array, which forms an electrostatic image to a recording body, exposed from a head surface with a corrosion resistant material. CONSTITUTION:An electrostatic recording head is constituted of multi-needle electrodes 3 arranged so as to provide air gaps 2 each for performing corona discharge with respect to a recording body, control electrodes 4 arranged to both sides thereof at a predetermined interval, a gold plating layer 11 formed to the surface of each electrode 4 and an insulating spacer 12. Each needle electrode 3 comprises a nickel wire with a thickness of 50 mumphi and a gold plating layer 10 with a thickness of about 5mum is applied to the part thereof exposed to the air gap 2 in opposed relation to the recording body. By this method, because gold plating treatment is applied to the discharge surface of each electrode, oxidation or surface deterioration is not generated even if the recording electrode is used for a long period of time and, therefore, stable discharge can be stably performed while the lowering in recording density can be prevented.

Title: Semiconductor photodetector and manufacture thereof
Inventor: KURODA FUMIHIKO
IPC: H01L31/10
Filed: 1988-01-20
Abstract: PURPOSE:To enhance controllability over junction positioning, to achieve a higher activation rate, and to reduce dark currents and multiplicationcaused noise by a method wherein P is so implanted into a photodetecting section in addition to Mg that the p will have a profile similar to that of the Mg in an Mg ion implantation process for the formation of a photodetecting section and a guard ring in an InP-based semiconductor photodetector. CONSTITUTION:On an n<+>-InP substrate 1, an n-type InP buffer layer 2, an InGaAs light-absorbing layer 3, an InGaAs buffer layer 4, an InP multiplication layer 5, and an InP low concentration layer 6 are epitaxially grown, which results in a semiconductor substrate 20. Next, from the primary surface of the semiconductor substrate 20, with an insulating film, such as an SiO2 film, or a photoresist serving as a mask, Mg tons are implanted into a photodetecting section and a guard ring, and P ions are implanted only into the photodetecting section. Exposure of the substrate 20 to a 20-minute annealing at 750 deg.C results in a deep diffusion of Mg into the guard ring and in an inclined junction. In the photodetecting section, with the implanted P atoms occupying the P site in the InP crystal, Mg may go into the In site more easily. This suppresses the diffusion of Mg for the formation of a step-type junction, enhances the activation rate, and reduces crystal defects.

Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device capable of forming an image without causing image defect even when a defective spot comes about on an image carrier by forming a toner image while keeping away from the defective spot on the image carrier, and capable of restraining the rise of the running cost. SOLUTION: Before forming an image, the position of a defective spot on a photoreceptor drum is previously stored in a storage means 52. The image signal of a test pattern where the image is formed to detect a defective spot is stored in the storage means 52. In this device. whether or not a defective spot exists on the photoreceptor drum is judged by making a control means 50 access the storage means 52 and confirming whether or not the position of the defective spot is stored in the storage means 52.  In the case of judging that the image can be formed while keeping away from the defective spot, the control means 50 calculates a position where the image can be formed while keeping away from the position of the defective spot, that is, a shifting position (main scanning direction and sub scanning direction) from an ordinary image-forming area based on the position of the defective spot and the size of transfer paper where the image is to be formed.

CONSTITUTION:Waste oil and natural oil sludge and a waste agent are burnt at 1,300 deg.C or more in a horizontal incinerator 8, and salts are fed to a vertical incinerator 6 togetherwith exhaust gas. The temperature of a lower part is adjusted tm 800 deg.C, approximate 40% of combustion gas causes condensation of organic waste liquid in a condensing can 3, the con densed organic waste liquid is sprayed in the vertical incinerator 6 for incineration. A rotary furnace 21 incinerates waste liquid not suited for a solid substance, mud, sludge, and condensed spray, and combustion exhaust gas is mixed in a secondary furnace 22 with exhaust gas from the condensing can 3. Inorganic salt in combustion gas is collected by means of waste in a recovery can 13 mounted right below the vertical incinerator 6. Drain from a neutralizing tower 6 is returned to a cooling tower, drain from the cooling tower is fed to a filtrate tank 18 and recovered as supply water in the recovery can 13, and drain is not drained to the outside of a system. Inorganic salt is automatically excluded to the outside of a system with the aid of a centrifugal separator 17, and this method forms a closed system in which drain is not entirely produced.

IPC: H01L23/52
Filed: 1995-01-24
Abstract: PURPOSE: To provide the process of a large selection ratio with an etching mask, excellent anisotropy, the least particle contamination and after-corrosion. CONSTITUTION: An Al metallic layer 3 is plasma etched away using an inorganic base material layer 4 containing fluorine such as SiOF, etc., as an etching mask. Thus, the etching mask made of the inorganic base material layer 4 containing fluorine is sputtered so as to form an AlFx base sidewall protective film 6 on the side faces of the Al base metallic layer 3 in the patterning step by the active fluorine fed by the sputtering step. Accordingly, the Al base metallic layer 3 is anisotropically patterned while the sidewall protecting film 6 not containing Cl at all has no possibility of causing after-corrosion. Furthermore, the complete effect can be given by using the sidewall protective film made of sulfuric base material together with the S sidewall protective film 6.
