Abstract: PURPOSE:To improve a mold releasing property, and prevent the occurrence of dark on an article surface by specifying the value of a strength ratio between the areal strength of Ois band and the areal strength of Cis band in the X-ray photoelectronic spectral method of a black lead material in a black lead mold. CONSTITUTION:A plastic molding black lead mold is 0.05 - 0.1 in the value of a strength ratio Ois/Cis between the areal strength of Ois band and the areal strength of Cis band in the X-ray photoelectronic spectral method of a black lead material. A black lead material being larger than 0.1 in the value of the strength ratio Ois/Cis is of a type wherein a functional group having oxygen atoms on the surface distributes at an extremely high ratio. Accordingly, it is likely to be wet with molten resin, other additives or the like, and results in causes of the deterioration in a mold releasing property and dark on an article surface. As the value of the strength ratio Ois/Cis is 0.05 - 0.1, it may be excellent in the mold releasing property with molten resin, other additives or the like, and there almost never occurs dark on an article surface. And, as being smaller than 0.05, it may not be changed in the effect at all in spite of high cost for producing a black lead material in such state.

IPC: H04N1/32
Filed: 1991-04-25
Abstract: PURPOSE:To reduce a time required for a communication procedure by sending a message end signal With a facsimile information field storing facsimile control information added thereto relating to a communication mode revision from a transmitter. CONSTITUTION:When it is required to revise the communication mode, a main control section 1 of a transmitter sends a message end signal resulting from linking facsimile information fields in which communication control information such as a communication speed, vertical resolution, a recording paper size and a minimum scanning time is stored similarly to the case with a digital instruction signal is sent to a reception side through a communication line 6 after the end of picture of one page. When a message confirming signal is received from the reception side, a communication control section 4 revises the communication control condition to continue the picture communication. Since a pre-message procedure including a training is not always restored for the mode change, the time required for the communication procedure is reduced and the communication efficiency is improved.

Title: Detecting device for slant angle
Inventor: BANBA NOBUO
IPC: G01C9/06
Filed: 1981-06-18
Abstract: PURPOSE:To detect the slant angle as an electric signal in a simple constitution, by providing a reflecting surface which always faces the direction of gravity, by detecting the displacement of a reflected beam by an incident beam which is inputted keeing a constant relationship with a reference surface. CONSTITUTION:A resistor part 7, a light conducting part 6, and an electrode 8 are formed on a substrate 5. Lead wires are connected to terminals 10-12. For example, the shape of the resistor part 7 is uniformly formed so that an equation Q=tan<-1>(X/1+X<2>) is satisfied by laser trimming and the like. In this way, the light conducting part, on which the beam 1a reflected by the reflecting surface, is conducted and the resistance value is decreased. Meanwhile, resistance of the part, on which the light is not irradiated, is high. Therefore relationship R3>>R2 is obtained. In this relationship, R1 is the resistance between the terminals 10 and 11 of the resistor part 7, R2 is the resistance of the light irradiated part of the light conducting body 6, while R3 is the resistance of the  dark part. Therefore the R3 is to be neglected and an equivalent electric circuit  as shown in the Figure is obtained. In this simple constitution, the slant angle  can be detected as the electric signal.

CONSTITUTION:A refrigerant passes through a compressor 3, a condenser 4 and then a refrigerant pipe 10, and is fed into the lower part of an evaporator 8 in a heat accumulating tank 6 to cool the upper end of a heat pipe 7. Then, the water 15 in the heat accumulating tank 6 serves as a heat source for the heat pipe 7, and a working fluid 18 in a container 17 evaporates, turns into an upward vapor stream, comes into contact with the wall surface of the container 17, releases the latent heat, condenses again, and is returned to the lower part. The latent heat released transfers to the evaporator 8 which is cooled. Therefore, the water 15 turns into ice 16 and deposits on the whole surface of the heat pipe 7 so that an ice layer having a uniform thickness is formed. On the other hand, the refrigerant evaporated at the evaporator 8 is led by the compressor 3 to the condenser 4 through a first refrigerant pipe 9. so that a load side air-conditioning circuit is brought in action to perform cooling operation.
