Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/04
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To smoothly transmit an original to a reception side without a trouble when the double face reading original is long by changing transmission control at detected auxiliary scanning length when the reading of the double face original is selected. SOLUTION: A reading circuit 14 reads an original picture by CCD and the like and outputs data to a signal line 14a. At the time of outputting a level '0' signal to a signal line 20i, the surface of an original is read. At the time of outputting a level '1' signal, a back face is read. At the time of reading, an auxiliary scanning detection circuit 28 detects auxiliary scanning direction length and auxiliary scanning resolution is designated to a signal line 20g. When an auxiliary scanning measurement start pulse is generated in a signal line 20h, auxiliary scanning length is obtained from the resolution of the signal line 20g and it is outputted to a signal 28a. When a double face reading selection key 24 is depressed and double face original reading is selected, original information are sequentially read as surface/back faces if the original is long.  At the time of selecting transmission as a one face original, the reading original is divided by the auxiliary scanning direction length of a fixed paper size, which corresponds to the original size of a main scanning direction and all information are transmitted as surface originals.

Filed: 1989-12-04
Abstract: PURPOSE:To eliminate the need to fit a blind lid and the need for the clamp by fitting a reverse flow preventive shutter which can send the inside air in a main body only to the outside in the air discharge opening of a cover. CONSTITUTION:The reverse flow preventive shutter 10 is fitted in the air discharge opening of the cover 1 and has a movable piece 10a and a grille as its fulcrum. When the temperature in the box body becomes high during illumination owing to the heat of a display tube, etc., the inside air is discharged from the reverse flow preventive shutter 10 with the wind pressure of an internally provided fan and fresh air is admitted through an air intake to cool the inside of the box body. While the display device is not in the illumination state, the reverse flow preventive shutter 10 is closed to prevent the outside air, dust, etc., from entering the box body. Consequently, any blind lid is not necessary and the need for the clamp for support is eliminated.

Title: Co-extruding pipe for two-liquid foam hardening tunnel natural ground stabilizing injection material
Inventor: TACHIMOTO TSUKASA
IPC: E02D3/12
Filed: 1993-12-17
Abstract: PURPOSE:To prevent an injection material from being foamed in an internal passage at the final stage of injection by extruding two liquid compositions different in composition through extruding passages separated from each other. CONSTITUTION:A co-extruding pipe l is constituted of inner/outer double pipes 11, 12, the first composition is injected from an injection port 13 and flows out through the passage 11 in the extruding direction, and the second composition is injected from an injection port 14 and flows out through the passage 12 separately. The first and second compositions of an injection material are extruded without being mixed in the co-extruding pipe 1. Even when the injection quantity of the injection material is reduced at the final stage of injection, the foaming of the injection material in the co-extruding pipe 1 is prevented, and the foaming region of the injection material in the downstream side passage from the outlet end of the co-extruding pipe 1 is rarely corroded in the pipe 1. The internal passage of the pipe l is narrowed and lengthened by the inner/ outer double pipes 11, 12, thus the corrosion suppressing effect of the injection foam material region is improved by the throttle valve action of the passage and an increase of the fluid resistance.
