Title: Oxide cathode
Inventor: KIMURA CHIKAO
IPC: H01J1/26
Filed: 1981-01-20
Abstract: PURPOSE:To enhance the electron emission characteristics and the life of an oxide cathode, by burying barium into the one surface of an oxide cathode at a predetermined depth. CONSTITUTION:A cathode substrate 1 and a cathode sleeve 2 are welded together, then a recessed surface is formed on the cathode substrate. Next, Ba ions are injected into the electron emission surface of the cathode substrate 1 at the depth of 0.1-2mu by means of an ion injection apparatus. Then, the surface of the cathode substrate on which Ba ions are buried is kept free from moisture as possible, while an oxide 3 is attached to the electron emission surface of the cathode substrate, for example, by spraying in the dry air or in the inert gas atmosphere. Afterwards, by inserting a heater 4 into the cathode sleeve 2, the oxide cathode is formed.

Title: Evaporative cooling apparatus
Inventor: OSAKABE HIROYUKI
IPC: F28D15/02
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To prevent a fluid refrigerant in a refrigerant tank from reversely flowing upon ergent stoppage and traveling on a slope (ascending slope). SOLUTION: A refrigerant tank 3 has an upper end side connected with a lower tank 21 being inclined rearwardly of a vehicle and hence is sharply inclined with respect to the lower tank 21. A reverse flow prevention plate 26 covering a lower side odf a vapor flow outlet 17 over the entire area of the tank in reft and right directions is fixed to an upper end surface of the cooling tank 3 inseted into the lower tank 21 with the aid of a screw and the like. Hereby, the fliid refrigerant reversely flowing toward the vapor flow outlet 17 strikes the reverse flow prevention plate 26 and is repelled, and hence is prevented from scattering from the vapor flowoutlet 17.  Further, although upon the vehicle traveling on an ascending slope a refrigerant liquid surface in the refrigeration chamber is relatively raised with repect to the vapor flow outlet 17 becouse the attitude of the cooling tank 3 approches a horizontal one, even if the refrigerant liquid surface moreraises from a lowermost portion of the vapor flow outlet 17, the liquid refrigerant is prevented from scattering from the vapor flow outlet 17 owing to the reverse flow prevention plate 26.

Title: Semiconductor laser device and its manufacture
Inventor: IKEDA HIROAKI
IPC: H01S5/20
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of crystallinity of a contact layer to a small area by permitting the cap layer to contain a smaller quantity of Al than that in an upper clad layer, a current block layer to contain Al and a protecting layer to contain a smaller quantity of Al than that in the current block layer. SOLUTION: A p-Al GaAs upper part second clad layer 107 in an area whereupon no resist film is formed is removed to form a ridge part 113, the shape of the ridge part 113 is formed to permit the width of a p-GaAs cap layer 108 to be wider than the width of the upper part of the p-Al GaAs upper part second clad layer 105, and the thickness of an n-Al GaAs current block layer 109 formed on the side of the p-GaAs cap layer 108 is thinned. Since the appearing area of the n-Al GaAs current block layer 109, which contains Al which is easily oxidized, to the surface is reduced, deterioration of the crystal of the contact layer is suppressed to a small area. Thus, a low resistance and high reliability semiconductor laser device is obtained.

IPC: G11B21/08
Filed: 1984-01-20
Abstract: PURPOSE:To form a reproducer of an information recording disk having a module search function to acceralete conventional visual search by shifting pickup from an information signal track, which is currently traced, to that two track ahead (after) the former in an extremely short time. CONSTITUTION:Visual research is acceraleted based upon the fact that the number of jumps (tracking) of tracks within the specific period is limited by a pulse interval (k) of a track control signal B. While a period TK1 of control limits of high-speed visual search depending upon frequency characteristics of gains of a tracking servo loop system is kept constant, a waveform of a track control signal A to be impressed to this system is changed and the number of tracks to be shifted is doubled. This means that by controlling a tracking control circuit in combination with the signals A and B, stylus can be shifted ahead by two tracks.

Abstract: PURPOSE:To simplify the assembling and to improve the reliability, by fitting the resilient hair-pin shaped board chip having the function of key and circular spring to the tubular face of hub member then securing to axially slidable supporter. CONSTITUTION:When operating the shift lever from neutral to bring the sleeve 130 to the right, hair-pin shaped synchronous driving member 140 is interlocked by the resistance against the sleeve 130, thereby the pressure section 146 contacts against the ring 50 to bring it to the right. Consequently inner conical section 51 is engaged with engaging means 60 through a ring 50. Here the teeth 152, 132 of ring 50 and sleeve 130 are out of phase thereby turning right of tooth 132 is blocked by tooth 52 to increase the engagement through inner conical section 51 thus to provide clutching function. When the difference of rotation between hub 120 and engaging means 60 becomes small, the sleeve 130 can turn to the right thus to engage between teeth 132, 62 and to complete the shifting.
