Title: Variable focus camera with folded type stroboscope
Inventor: NAKAYAMA HARUKI
IPC: G02B7/10
Filed: 1987-10-09
Abstract: PURPOSE:To secure the linking action of the action of a stroboscope to other functional elements by equipping a switch which utilizes the standing and housing action of the stroboscope and whose constitution is simple. CONSTITUTION:As for the control of the opening and closing of a barrier K, the barrier K is controlled to be opened when a release lock is released and a folding cover 23 is in a nearly complete erect state and said opening state is prohibited until the folding cover 23 is in a nearly complete housed state and a main switch becomes in an off state. Then, the unnecessary opening action of the barrier K is not performed until the release of the release lock even if the opening and closing of the barrier K is performed in interlocking with the standing and housed action of the folding cover 23. Even if the folding cover 23 is touched by mistake at the time of photographing in the erect state of the folding cover 23, the barrier K is not closed and failure in photographing can be prevented. Thus, the link of the stroboscope mechanism to other functional element can be secured.

Title: Manufacture of semiconductor device
Inventor: YAMAGUCHI TADAKATSU
IPC: H01L21/225
Filed: 1984-12-04
Abstract: PURPOSE:To avoid the increase of the resistance of a spin-on diffusion layer by removing an oxidizing film formed on the peeling of a photo-resist by oxygen plasma by hydrofluoric acid group chemicals. CONSTITUTION:An insulating oxide film 2 is shaped onto the surface of a semi conductor wafer 1, the oxide film 2 in a diffusion section is removed selectively while usint a photo-resist film 3 as a mask through photoetching to bore a window, and the residual resist film 3 is ashing-removed by oxygen plasma. An oxidizing film 4 in approximately 25Angstrom  is formed to a diffusion window section exposed to oxygen plasma at that time. The resistance of a diffusion layer is increased by approximately 5% through spin-on diffusion as he oxidizing film is left as it is. The resistance of the diffusion layer is elevated when adopting oxygen-plasma peeling because the oxidizing film shaped by oxygen plasma functions as a barrier to a spin-on diffusion source, but the oxidizing film can be removed easily through treatment for approximately thirty sec by hydrofluoric acid group chemicals such as a solution at the rate of 50% hydrofluoric acid: pure water =1:10.

Title: Image forming device
Inventor: FUJII HARUO
IPC: G03G15/06
Filed: 1987-10-12
Abstract: PURPOSE:To prevent an image from causing uneveness and fogging pattern by providing a means for controlling a power source voltage so that an electric field between a developer carrying means and the surface of a latent image carrier can be kept constant. CONSTITUTION:It is difficult to keep a distance between the developer carrying member (sleeve) 9 and the photoconductor layer 2 of the latent image carrier (conductive drum) 1 constant. The unevenness, etc., in the image is caused since the amount of developer T which moves to the surface of the photoconductor layer 2 from the sleeve 9 changes by the variation of said distance. Then, a light source 16 is made to project between the surface of the photoconductor layer 2 on a non-recording position and the sleeve 9, and light which passes through the gap is received by a photodetector 1. An output voltage from the photodetector 17 is made to pass through an amplifier 18 and the output voltage from an AC power source 15 is changed so that the AC electric field between the photoconductor layer 2 and the sleeve 9 is kept constant. Thus, the uniform image can be always obtained even if the gap between the photoconductor layer 2 and the sleeve 9 varies.
