Title: Image forming device
Inventor: UEZONO TSUTOMU
IPC: G03G15/05
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent wear on an electric conductor layer and image deterioration by providing a high polymer covering layer so that a specified part on the electric conductor layer of a latent image charge holding medium constituted of a pyroelectric body layer and the electric conductor layer provided on the back of the pyroelectric body layer is covered. SOLUTION: A thermal head 4 selectively heats the latent image charge holding medium 3 having the pyroelectric body layer 1a in accordance with an image signal. A conductive film 5 neutralizes a charge on the medium 3 generated by pyroelectric effect. An electrostatic latent image 17 formed on the medium 3 is developed by an electrified coloring medium, and is transferred on a recording paper 1. The medium 3 is an endless belt constituted of the layers 1a, 1b and 1c. For example, polyvinylidene fluoride is used in the layer 1a, the high polymer film having an aluminum pyroelectric layer is used in the layer 1b and the high polymer film having an adhesive layer is used in the layer 1c. Thus, a phenomenon that the layer 1b is worn and stuck is eliminated and the image deterioration is prevented even though consecutive recording is performed.

Title: Wiring method for width of plurality of wires of lsi
Inventor: OKI TSUTOMU
IPC: H01L21/82
Filed: 1993-12-16
Abstract: PURPOSE:To prevent the enlargement of a chip and to make it possible to achieve high integration density by performing the specified wiring so that the wiring interval becomes the best with respect to various wiring widths in the wiring between the pad and the IO cell of the LSI of a cell base. CONSTITUTION:A wiring width Wi, which is assigned to a wiring grid Ri later, is already known. Therefore, it is assumed that the wiring with the wiring width Wi is performed for the wiring grid Ri. When the wiring interval between the temporary wiring and a net N is less than a spacing S, it is assumed that the wiring of the wiring grid Ri is finished. The right or wrong of the use of the wiring grid can be judged only based on the right or wrong of the wiring of the grid of Ri by this setting method. In this way, the wiring grid at the position that is 1/2 of the width of the wiring, which is assigned to (wiring spacing) + (facing wiring grid) from the line of the bent wiring, is added in the wiring process. Therefore, the interval between the bent wirings can be the spacing S. Since the wiring grid on a pad is located at the outside by 1/2 of W, the formation of the bay-shaped wiring between the pad and the wiring can is prevented.

Title: Semiconductor light emitting device
Inventor: OKAZAKI YOJI
IPC: H01S3/10
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To lower the oscillation threshold of a semiconductor light emitting device so that the light emitting efficiency of the device may be improved by using a Lyot filter as a wavelength selecting means for locking the light emitting wavelength of the device to a single wavelength. SOLUTION: A light beam 11 emitted from the rear end face 10a of a semiconductor optical amplifier 10 has a wavelength of 800-820nm, but the light which returns to the amplifier 10 after the light is reflected by a mirror 13 has a single wavelength of the same wavelength band due to the wavelength selecting action of a Lyot filter 14. Therefore, the light emitting wavelength of the amplifier 10 is locked to the single wavelength. The light 11F having this wavelength is amplified while the light advances forward in the amplifier 10 and emitted from the front end face 10c of the amplifier 10. Since the transmission factor of the light having a wavelength of 810nm through the filter 14 is extremely high (99%), the loss of a semiconductor light emitting device is suppressed to a small value and the threshold oscillating current of the device is reduced.  In addition, the efficiency of the device is improved. Therefore, high output light 11F can be obtained from the device.
