Title: Manufacture of hydrogen storing material
Inventor: FUKUBE YOSHITO
IPC: C01B3/00
Filed: 1979-09-11
Abstract: PURPOSE: To enhance the hydrogen storing capacity of a material by melting Ti, Zr, Hf or a rare earth metal and Fe, Co or Ni in an atmosphere of hydrogen or a hydrogen-rare gas mixture to form an intermetallic compound.  
     CONSTITUTION: One or more among Ti, Zr, Hf and rare earth metals as the 1st starting material and one or more among Fe, Co and Ni as the 2nd starting material are melted and solidified in an atmosphere of hydrogen or a mixture of hydrogen and a rare gas such as Ar to form an intermetallic compound of both the metals. In the melting and solidification hydrogen in the atmosphere is absorbed in the materials and bonds to the intermetallic compound. This absorbed hydrogen accelerates the hydrogen absorbing action of the resulting hydrogen storing material in activation. This hydrogen storing material can be activated well without carrying out heat treatment.

Title: Semiconductor laser
Inventor: UNOSAWA HIRONOBU
IPC: H01S5/00
Filed: 1988-05-11
Abstract: PURPOSE:To reduce an astigmatism by providing a second current block layer formed of a material having band gap narrower than that of an active layer outside a first current block layer. CONSTITUTION:A current is injected from a groove opened on a first block layer 14 to an active layer 12 through a second clad layer 13. Carrier injected to the active layer is diffused laterally of the layers 13, 12 to form a gain distribution, thereby starting a laser oscillation. In this cash, since the carrier concentration of the layer 12 is high, carrier diffusing length is shortened, its gain distribution is mainly formed in the layer 12 under a groove opened on the layer 14, its shape becomes abrupt, and the gain becomes high only at the part under the first groove. On the other hand, a laser light flows out from the layer 12 to extend vertically. In this case, a second block layer 16 is operated as an absorption layer for a laser light. Thus, an astigmatism is reduced.

Title: Soldering iron
Inventor: MIZUTA MINORU
IPC: B23K3/03
Filed: 1980-08-22
Abstract: PURPOSE:To heat a soldering iron quickly at the start of its use by properly selectively using a main heating element of small wattage and an auxiliary heating element of large wattage having large positive temp. characteristics. CONSTITUTION:In the case of heating an iron tip 4 of low temp. to a working temp., a plug 22 is inserted into a receptacle, and a button 17 is pushed to close a switch 16. Then, electric power is supplied to both of a main heating element 11 and an auxiliary heating element 12, and since the resistance values of both elements 11, 12 are small at low temps., a large quantity of heat is generated. Hence, the temp. of the iron tip 4 rises sharply. Next, at the point of the time when the tip 4 seems to have attained an adequate temp., the switch 16 is opened. Thereafter, an approximately constant temp. is maintainted by the element 11 alone, and therefore soldering work is carried out in this state. When the temp. of the tip 4 lowers, again the switch 16 is closed to cause auxiliary heating with the element 12. At this time, the tip 4 and the element 12 are of elevated temps., and therefore the wattage of the element 12 is relatively small whereby overheating of the tip 4 is prevented.

Title: Method and apparatus for memorizing and accessing character and electronic printer using same
Inventor: JIEROOMU AARU DAAMU
IPC: G06K15/00
Filed: 1983-06-30
Abstract: Electronic printer apparatus in which the intensity of the beam of a cathode-ray tube is controlled during successive beam sweeps to display and project onto a rotating electrostatically-charged surface an image of successive slices through a row of characters to be printed, the latent line images thus formed being then converted to a toner image for subsequent transfer to a page of paper. Digital information bits organized in bytes and representing slices through each character are stored in respective areas of a permanent memory storage device. The appropriate slices of the characters are accessed in response to character-representing input signals, and are read out serially to control the beam intensity during each sweep and thus display, along the sweep, the desired slice through the row of characters. The stored bits for each character slice are organized into various integral numbers of x-bit and y-bit bytes, preferably 8-bit and 6-bit bytes, the number of bytes of each type for each character slice depending on the bit width of the corresponding character cell; there are no extra or left-over bits beyond these included in the two types of bytes. The so-stored bytes of differing bit content are accessed byte-by-byte, enabling simplification and reduced cost of the apparatus.
