Patent JP-H06127307-A (JP)
Title: Lighting apparatus
Inventor: SAKATA MASAO
IPC: G02B6/00
Filed: 1992-10-13
Abstract: PURPOSE:To prevent a leakage of the light passing through the inside of a light transmission body, even though a cut is generated or a liquid such as fat and oil is attached on the surface of the light transmission body to transmit the light through a transparent body. CONSTITUTION:A light transmission body 24 is formed by providing protective layers 31a and 31b which have the refraction index smaller than a transparent body light guide 25, on the surface of the guide body 25. The first hologram 29 to receive and diffract a parallel luminous flux from a light source 21 is provided at the lower end of the light transmission body 24, while the second hologram 30 to receive the luminous flux transmitted inside the light guide 25 and diffract it to the outer side is provided to the upper end. The incident angle of the reflection surface of the luminous flux is set larger than the critical angle at the interface between the light guide and the protective layers. Consequently, since the luminous flux is not refracted and injected to the protective layers by reflected perfectly by the interface, the light is never leaked to the outer side of the light transmission means after refraction and injection to the liquid side, even though such a liquid is attached on the surface of the protective layers, for example.

Title: Temperature control device
Inventor: FUKUYAMA HIROTAKA
IPC: G05D23/19
Filed: 1991-11-15
Abstract: PURPOSE:To surely set up a heating object to a controlled objective temperature by forcedly feeding current to a heating element until a detected temperature reaches the controlled objective temperature or a prescribed time has elapsed when the detected temperature does not reach the controlled objective temperature within the prescribed time after stopping current supply to the heating element. CONSTITUTION:When temperature detection by a thermistor 4 reaches heating stop temperature at the temperature rise of a roller 1, a heating stopping means 11a stops the current supply of a heater 1a. When the detected temperature reaches the controlled objective temperature within the prescribed period, a current supply control restart controlling means 11b restarts the current supply control of the heater 1a when the detected temperature does not reach the controlled objective temperature within the prescribed period, a forced heating control means 11c outputs a forced ON signal by a trigger signal to forcedly turn on the heater 1a until the detected temperature reaches the controlled objective temperature or the prescribed time has elapsed. Consequently the heating object can be surely set up to the objective temperature.

Title: Developing device
Inventor: ISHIWATARI TAHEI
IPC: G03G15/09
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To stably form an image extending over a long term. SOLUTION: A developer carrier 2 constituted so that an elastic layer 4 is covered with a conductive layer 5 is used as the component of this developing device. An intermediate layer 101 is disposed between the layers 4 and 5 and the respective volume resistivity thereof are set so as to establish the relation of the layer 5 > the layer 4 > the layer 101 and so as to satisfy the relation of the layer 5 < the layer 4 < the layer 101. By providing the developer carrier constituting the developing device with at least the layer 4, covering the outside circumferential surface of the layer 4 with a tube and disposing the layer (resistance adjustment layer) 101 between the layer 4 and the tube, developing bias can be uniformly applied without being affected by the partial variance of the resistance of the layer 4. Thus, the image without density irregularity can be formed.  Besides, since the developing bias is prevented from being leaked to a latent image carrier, the high-density image without the density irregularity can be formed. Thus, the high-quality image can be stably developed extending over a long term.

Abstract: PURPOSE: To secure connection between a network and an analog telephone circuit by providing a circuit exchange having an interface for connection to the analog telephone circuit within the network. CONSTITUTION: When a terminal equipment 320 calls an analog telephone set 380, a multi-input adaptor, 310 sends the information data on the call number as well as a calling command to a circuit exchange 360 via a communication line 350, a multiplex controller 340 and a communication line 370 and outputs a call signal via a communication line 390. The telephone set 380 transmits and receives only the voice signals and the information data and therefore the multiplex data that are inputted to the adaptor 310 from the telephone set 380 include the voices and information data only. Thereby the adaptor 310 discriminates these voices and data and outputs them to an equipment 320 via a communication line 332 and also supplies only the voices and information data to the telephone set 380 via the line 350 out of the multiplex data received from the equipment 320 via the line 332.
