Title: Thawing/cold storage antibacterial device for frozen foods, or the like
Inventor: UENO NOBUO
IPC: A23L3/365
Filed: 2000-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a thawing/cold storage antibacterial device which serially performs thawing, cold storage, and antibacterial actions on frozen foods. SOLUTION: In the thawing/cold storage antibacterial device in which a heat conductive metallic plate 1 equipped with a Peltier element 2 which continuously performs thawing action and cold storage action as the flowing direction of a current is switched is covered with a cover 12, a thermo-sensor 14 is installed to the metallic plate 1 so that, when the sensor 14 detects that the temperature rise of the metallic plate 1 reaches a prescribed range or the surface temperature of the plate 1 reaches a set value, the device may perform thawing and cold storage on the frozen foods, etc., by sifting the thawing action to the cold storage action by issuing a cold storage converting instruction upon receiving a detect signal from the sensor 14.  In addition, an antibacterial ability is given to the inside of the cover 12 by forming an ion generating layer 15 which generates negative silver ions, etc., on the metallic plate 1. Therefore, the thawing and cold storage actions on the frozen foods, etc., can be performed serially in the same cover 12 and the thawing can also be performed in an appropriate temperature region and in a short time. In addition, since the thawing action can be sifted immediately and automatically to the cold storage action, the thawing, cold storage, and antibacterial actions can be performed without requiring labor nor monitoring.

Title: Method of manufacturing low-resistance p-type semiconductor and semiconductor element
Inventor: SENDAI TOSHIAKI
IPC: H01S5/323
Filed: 2000-08-24
Abstract: PROBLEM TO BE SOLVED: To efficiently lower the electrical resistance of a p-type semiconductor or the driving voltage of a semiconductor element that exerts light emitting/ receiving actions, etc. SOLUTION: Ion plasma type electron beam irradiation equipment 100 generates an electron beam that irradiates a wide area. The generated electron beam is emitted to the outside through a thin metallic sheet 108 forming the external surface of a beam emitting window 107 intercepting the outside air. Immediately below the window 107, the p-type semiconductor is arranged in almost parallel with the metallic sheet 108 at an interval of, for example, about 20 mm from the window 107. When the surface of the p-type semiconductor is irradiated with the electron beam by using the equipment 100, the electrical resistance of the semiconductor can be lowered effectively in about three minutes which are extremely shorter than the time required by the conventional electron beam irradiation equipment.  The reason is that no physical requirement that strongly restricts the area, etc., of the window 107 exists and the width of the electron beam becomes broader and, accordingly, it becomes unnecessary to repeat scanning many times for a long time.

Title: Noise shaper
Inventor: FUKUHARA YUKIO
IPC: H03M3/02
Filed: 2000-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a noise shaper of a pole shift type where a pole on the Z plane of a transfer function is shifted from its origin, so as to suppress an idling pattern.

Title: Optical device having wavelength selectivity
Inventor: TOYOSHIMA TAKAYUKI
IPC: G02B6/293
Filed: 2000-09-05
Abstract: PROBLEM TO BE SOLVED: To provide an optical device having wavelength selectivity which facilitates manufacture and reduces manufacturing costs. SOLUTION: The optical device 21 having wavelength selectivity is provided with a light guide plate 22 and a multilayer film filter 23 formed in the surface 22a. The multilayer film filter 23 is formed so that the film thickness is continuously changed within the surface 22a. When mixed light including light different in wavelength (plural wavelength components) is made incident diagonally within the light guide plate 22, since mixed light advances while repeating reflection between two surfaces 22a and 22b of the light guide plate, a position where mixed light is made incident on the multilayer film filter 23 is changed at a fixed deviation quantity in accordance with an incident angle. Thus, mixed light is separated into light different in wavelength component by the multilayer film filter 23.  Since the optical device 21 is manufactured only by forming the multilayer film filter 23 in the surface 22a so as to continuously change in the surface, the number of working processes and the handling time are reduced.
