Title: Production of diethylenetriamine
Inventor: KOMIYAMA TADASHI
IPC: C07C209/00
Filed: 1983-10-06
Abstract: PURPOSE:To obtain the titled compound in high yield, by reacting ammonia with monoethanolamine at a specific molar ratio or above in the presence of a phosphorous-containing substance and ethylenediamine. CONSTITUTION:Ammonia is reacted with monoethanolamine at >=11 molar ratio between the ammonia and the monoethanolamine in the presence of a phosphorus-containing substance, e.g. ammonium dihydrogenphosphate, and ethylenediamine to afford the aimed diethylenetriamine. The amount of the phosphorus- containing substance to be used as a catalyst is usually about 0.01-1mol expressed in terms of phosphorus based on 1mol monoethanolamine. If the molar ratio between the ammonia and the monoethanolamine is below 11, the ethylenediamine is also consumed. Preferably, the ratio is 10-30, and the selectivity for the diethylenetriamine is improved with increasing molar ratio. However, the volume efficiency of a reactor is deteriorated.

Filed: 1980-12-28
Abstract: PURPOSE:To achieve high-density recording with superior resolution by scanning at least either one of a light emitting element array with large light emission surfaces and an imaging element array forth and back in parallel to a photosensitive surface. CONSTITUTION:Emitted luminou flux from an LED12 with large light emission area is reduced to (m) time (m=a/b) through an imaging lens 13 to form an image on a photosensitive surface 14. The extent (d) of the movement of the lens 13 is c/1+m, where (c) is the pitch of the LED12. Further, the irradiation area Si of an imaging part is m<2>So, where So is the light emission area of the LED12. Namely, magnification (m) is determined by the So and necessary resolution to be found, i.e., the irradiation area Si of the imaging part, and the extent (d) of the movement of the imaging lens 13 is determined by the pitch (c) of the LED12 and pitch (c). Under said conditions, the lens 13 is moved at a constant speed by the distance (d) in a main scanning direction E to expose the light emission pattern of the LED12 to the photosensitive surface with the same width F with the pitch (c).

Title: Sliding part manufactured by injection molding method and injection molding die
Inventor: UEDA KOSHIRO
IPC: F04C2/344
Filed: 1990-07-16
Abstract: PURPOSE:To prevent cold slag from appearing on a sliding surface and also prevent weld lines from being generated thereon by setting the sectional area of a flow path of a molding material running into a recessed section as a cold slag storage formed in a mold larger than the sectional areas of other flow paths and making the cold slag appear as a recessed section on a molded sliding part. CONSTITUTION:A recessed section 14 forming a cold slag storage is formed on a site forming a projected section on a non-sliding surface of a mold 7 facing the left end side of a cavity 13. Cold slag existing at the end of a molding machine flows from a gate 8a into the mold, and as the flow path sectional area of the cavity 13 is made twice as large as the flow path sectional area of a cavity 12 and the recessed section 14 is formed on the position facing the gate 8a, the cold slag can be passed through the cavity 13 and flowed into securely the recessed section 14. As the appearance of cold slag is not recognized on the sliding surface of a formed vane, the surface roughness of the sliding surface is not lowered and the generation of weld lines generated by the appearance of cold slag can be prevented.
