Title: Lead frame material for ic package
Inventor: YAMADA HIROSHI
IPC: H01L23/50
Filed: 1994-07-18
Abstract: PURPOSE:To prevent formation of oxide and improve soldering by using Fe-Cr based material containing Cr (specified wt.%) as lead frame material, and plating the whole surface with Ni, Pd, Au or Ag after punching work. CONSTITUTION:Fe-Cr based material containing 5-10wt.% Cr is used as lead frame material for an IC package, and the whole surface is plated with Ni, Pd, Au or Ag after punching work. An IC chip is bonded to the die pad of the lead frame material. The IC chip is wire-bonded to the lead of the lead frame material. The IC chip is packaged together with the die pad by using package material like resin. In virtue of the plating process, surface oxidation of the lead frame material is prevented when the lead frame material is heated in each process. Hence the soldering of the lead frame and its adhesion to the package material can be improved.

Title: Moisture proof container
Inventor: MIYAZAKI SHIGEO
IPC: A47B81/00
Filed: 1989-07-21
Abstract: PURPOSE:To maintain the humidity in compartments constant by a method wherein two or more compartments in a container are connected to a duct which leads to a dryer, and the openings of dampers are respectively controlled by humidity sensors installed in the compartments. CONSTITUTION:Openings 9 and 12 located on the rear walls of upper and lower compartments 3 and 4 are provided with dampers 10 and 13 which are controlled by a damper driving apparatus 11. A dryer 15, to which the opening 9 and 12 are connected, consists of drying agent mounted above a duct 16 and a regeneration heater 18 and is installed on the outside of the rear of a humidity preventing container 1. A regeneration on-off damper 20 is installed on an opening 19 and controlled by a damper driving apparatus 21. The humidity in the compartments 3 and 4 are detected by humidity sensors 23 and 24 and set by humidity setting devices 7 and 8. For example, when the humidity sensor 23 detects the humidity in the compartment 3 exceeding the set humidity, the detected signal brings the damper driving apparatus 11 in operation to open the on-off damper 10, so that the compartment 3 is connected to the dryer 15 and the drying agent absorbs moisture to reduce the humidity in the compartment 3 to the set humidity.

Title: Image forming device
Inventor: FUJIMOTO MAKOTO
IPC: G03G15/22
Filed: 1987-07-29
Abstract: PURPOSE:To enable minituarization and cost reduction of a device to be performed by making a size of a light emission element small, by a method wherein the light emission element has an image density of not less than a specific value and, besides, a projection means for projecting a light image by the light emission element on an image carrier by magnification. CONSTITUTION:A LED array 9 is arranged parallel to a drum 7 in a lengthwise direction of the photosensitive material drum 7, and its length is fairly shorter than that of the photosensitive material drum 7. Therefore, an effective image width at the photosensitive material drum 7 is illuminated by using a projection lens 10. In that case, a length of the LED array to be used is determined by a pixel density, i.e. the number of PEL necessary at the photosensitive material drum 7, the number of PEL at the LED array 9, and a magnification of the projection lens. That is, the system is constructed as follows: the LED array having the number of PEL larger than that necessary on the photosensitive material drum 7 is used, the image is magnified with the projection lens 10, is projected on the photosensitive material drum 7, and the number of PEL required on the drum can be obtained. Therefore, a size of the LED array to be used can be miniaturized.

Title: Bsi light transmitting system
Inventor: FUJIMOTO NOBUHIRO
IPC: H04B10/07
Filed: 1988-07-29
Abstract: PURPOSE:To simply constitute a code converting circuit and a reverse converting circuit by transmitting one datum with the light of plural wavelengths. CONSTITUTION:A control circuit 14, when the output of AND gate circuits 12 and 13 is '1', respectively generarates a voltage V2 for the light output of a wavelength lambda2 and a voltage V3 for the light output of a wavelength lambda3. When the output of the AND gates 12 and 13 is both '0', the input dat are not fetched. In other period, based on the fetched input data, when the data are '0' and '1', the circuit generates a voltage 0 to eliminate the light output and a voltage V1 for the light output of a wavelength lambda1. Thus, any voltage of 0, V1, V2 or V3 is impressed from the control circuit 14 to a wavelength converting element 21 and the condition, in which the light output is absent or the light output of wavelengths lambda1, lambda2 or lambda3 is present, is obtained.
