Title: Manufacture of optical switch device
Inventor: HORIBA TAMOTSU
IPC: G02B26/02
Filed: 1991-10-11
Abstract: PURPOSE:To improve the manufacturing performance by greatly simplifying a structure for selectively turning off the optical path of an optical fiber without decreasing the precision of an optical coupling part. CONSTITUTION:A comb-shaped slit 2 is formed in a substrate 1 made of a material which can deform elastically to provide four movable tongue parts 3 in total which are partitioned with the slit 2. Four optical fibers 4 are fixed on the substrate 1 through holders 5 by adhesion, etc., while positioned in parallel to one another and crossing the respective tongue pieces 3 longitudinally. The optical fibers 4 and holders 5 are cut at parts corresponding to the main slit 2a while fixed to the substrate 1, and consequently the optical fibers 4 have mutually opposite cut surfaces. Therefore, a switching function which turns off the optical path of the optical fiber 4 corresponding to the displacement of the cut surface of the optical fiber 4 through the pressing operation of the movable tongue piece 3 is obtained.

Title: Output driving circuit
Inventor: SANGU FUU DONGU
IPC: G11C11/407
Filed: 1991-10-11
Abstract: PURPOSE: To prevent the chip area of DRAM from being considerably reduced through the use of an output driving circuit which does not need two PMOS pull-up transistors which are stacked for interfacing low on chip power voltage against off chip bus voltage. CONSTITUTION: An on-chip pump circuit generates voltage required at the time of interfacing an external bus in a first execution example. In a second execution example, external bus voltage is detected and external bus voltage is compared with on-chip VDD at the time of a try state. A third execution example is the combination of the first and second execution examples. The external bus is compared with VDD in the second execution example. Voltage higher than VDD is generated in the on-chip as in the first execution example. Voltage generated in the pertinent on-chip is used for controlling the PMOS pull-up device when bus voltage is higher than VDD instead of bus voltage.

Abstract: PURPOSE:To detect a moment when a tool is contacted with a bonding surface or a moment when the tool is separated, without an electric contact point, by detecting the change in leak current or voltage flowing in a transducer when the bonding tool is contacted to or separated from the bonding surface. CONSTITUTION:When a capillary 3 is not contacted with a bonding surface, a leak current (a solid line l) always flows in a wiring 7 at a constant level regions A, C and E). At a moment when the capillary 3 is contacted to the bonding surface [a point (p) and a point (r)], the level of the leak current is changed and lowered (regions B and D). At a moment the capillary 3 is separated from the bonding surface [a point (q) and a point (s)], the level is recovered to the constant leak current level. In the first bonding 21 or the second bonding 22, the point (p) or the point (r), where the leak current level is changed, is detected by a leak-current detector 8. After the specified time, an instruction signal CS is imparted to an oscillating power source 6 so that ultrasonic waves are oscillated for a specified time period as shown by dotted lines (m) and (n).

IPC: H01S5/00
Filed: 1992-10-30
Abstract: PURPOSE:To embody a DFB laser for an analog optical communication which reduces spacial hole burning, which improves linearity in a special example of current-optical output, and which has an excellent strain characteristic by a method wherein an axial direction light intensity distribution within a resonator of the DFB laser is made uniform. CONSTITUTION:On an n-InP substrate 1 having a diffraction grating 4 on the surface, a SiO2 mask which has an opening part in its center, which is narrow in a center part in the oscillator direction, and which is wide in an end surface part is formed. By a MOVPE selection growth system, an n-InGaAsP optical guide layer 2 selectively grows. As a composition of InGaAsP becomes a long wavelength in a wide part of SiO2 pattern width and a short wavelength in a narrow part of the pattern width, a refractive index of a light guide layer becomes large at both ends of the oscillator and small in its center part. Accordingly, a coupling coefficient k of the diffraction grating becomes large at both ends of the oscillator and small in its center part. Thereafter, the SiO2 mask is removed and a DH structure having an active layer 3 is formed to manufacture a DFB laser.

Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To eliminate a refrigerant leakage and to enhance the degree of freedoms of a design by brazing a heat transfer tube bent in a zigzag state on a plate, and forming a herringbone or single side herringbone pattern on an outer wall of the tube in a plate laminated state. SOLUTION: A plate 1 is formed by brazing heat transfer tubes 2, 2' bent in a zigzag state to both surfaces of a thin metal plate. The plate type heat exchanger is formed by laminating the plates 1. Bent patterns of the tubes 2, 2' are formed in the state that the plates 1 are laminated in a similar pattern to a herringbone type plate. Since refrigerant flows through the tubes 2, 2', a very high pressure resistant strength can be obtained. Thus, as long as the tube is not broken, no fear of refrigerant leakage occurs. The plate 1 has two openings 6 to form a water side channel of the plate 1 between the openings 6.

IPC: F24F13/20
Filed: 1994-11-28
Abstract: PURPOSE: To provide an air conditioner wherein an air stream does not suddenly change, or noises do not increase, and the directivity of air is improved by a method wherein an auxiliary air direction-changing plate is added in an air passage between a blower and air direction-changing plate, and the width of the air passage with which the auxiliary air direction-changing plate is confronted is widened. CONSTITUTION: When the directions of a pair of air direction-changing plates 27, 28 and a single auxiliary air direction-changing plate 30 are faced downward respectively, air which flows along an upper wall 24 of an air passage can be rectified and made to face downward. Therefore, the directivity of the air can be improved, and light hot air which is easy to rise can be made to reach a floor surface, and the inside of a room can be favorably heated from the lower part such as the floor surface, etc. At this time, the width of the air passage becomes narrower by a thickness dimension P of the auxiliary air direction-changing plate 30, but a sudden narrowing of the width of the air passage can be eliminated by forming a recessed part 50 on the upper wall 24 of the air passage. By this method, a sudden change of the stream of air, and the increase of noises are suppressed.

IPC: A47C3/18
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To prevent a tube, a spring member, etc., of a gas spring from being broken by rotational force and to improve durability. SOLUTION: A spring member 35 is positioned in a recessed part 24 for storing a sprig of a guiding member 21 and is arranged between the guiding member 21 and an elevating/lowering member 25 and the elevating/lowering member 25 is restricted in the rotational direction to the guiding member 21 and is movably arranged only in the axial direction. Therefore, when a person sit on the chair leaves from the seat part, even if a gas spring 13 rotates, the elevating/lowering member 25 only elevates and lowers in the axial direction along the guiding member 21 and a rotational force can be prevented from being generated in the spring member 35. In addition, as the rotational force does not act on the spring member 35, it does not bite a tube 14 and in addition, when the spring member 35 is stretched and contracted, abnormal sound and breakage can be prevented from being generated.
