Title: Lead frame of semiconductor device
Inventor: HIROI MITSUMASA
IPC: H01L23/50
Filed: 1991-10-29
Abstract: PURPOSE:To avoid the deformation of the title lead frame by thermal stress or the stress of contracting resin while increasing the bonding time carrier capacity as well as avoiding the undercut of outer lead. CONSTITUTION:A support bar 33 smaller in width than a tie bar 32 is orthogonally connected to the tie bar 32 arranged on a corner part of an island 31.

Patent JP-H04157771-A (JP)
Title: Constant current circuit
Inventor: FUKUTOME FUJITO
IPC: H04B10/572
Filed: 1990-10-20
Abstract: PURPOSE:To always maintain a current value of a circuit current flowing from a current source for a circuit by continuously detecting a current value of a current flowing from a current source for a light emitting element by current control means, and sending a control signal in such a manner that a current value of a difference between a maximum current value and a detected current value flows by a current source for control. CONSTITUTION:Since an emitter current of a transistor Q1, i.e., a bias power source IB of a light emitting element becomes '0' when the Q1 is OFF, a voltage across a resistor R3 is '0'. RD is so decided as to become VBE(Q2)+VBE(Q1)+VBE (Q4)+ID.RD=Vc. When a maximum current flows to the Q1, if R3 is so decided as to become VBE(Q2)+VBE(Q3)+VBE(Q4)+R1.RB=Vc, no voltage is generated at the RD, and hence the ID becomes '0'. If the IB flows from a '0' state, a voltage is generated across the resistor R3, but since the VBE of the Q2, Q3, Q4 are constant, a voltage across the RD is reduced so that the entire voltage becomes the Vc. If the IB is increased, the ID compensates it so that the current IT for a circuit always becomes constant.

Title: Plastic clad light transmission fiber and bundled fiber
Inventor: UNOKI MASAO
IPC: G02B6/04
Filed: 1987-11-12
Abstract: PURPOSE:To obtain the title fibers which are low in transmission loss in a UV region by forming a clad material of a fluorine-contained polymer having a cyclic structure in the main chain. CONSTITUTION:The clad material of the plastic clad light transmission fiber having the core consisting of quartz glass or optical glass is formed of the fluorine-contained polymer having the cyclic chain in the main chain. The fluorine-contained polymer having the cyclic chain in the main chain has no crysatllinity and has a high content of fluorine; therefore, said polymer is transparent and is low in refractive index. Since the polymer has high strength and has a good leak characteristic to the core material, the strength of the light transmission fiber is high; furthermore, there are not cured parts and C-H bonds and, therefore, the light transmittance of the UV region (200-400nm) is high. Generation of heat by UV absorption is thereby decreased and the decrease in the transmission quantity of UV rays is obviated.

Abstract: PURPOSE:To obtain a superconducting element having a magneto-resistance effect, which can increase a signal-to-noise ratio, by alternately arranging in a row on a substrate superconducting portions, having a large critical current density, and weak connecting portions, having a small critical current density. CONSTITUTION:A Si thin film 11 is deposited on a SrTiO3 substrate 10, and is processed by a dry etching technique, so that there are produced fine patterns. When the substrate is maintained at a temperature of 650 degrees Centigrade, and a Y1Ba2Cu3 O7-x (thin film (a superconducting thin film) 13 is deposited on the substrate by controlling in such a manner that the composition ratio of this thin film can be Y:Ba2:Cu=1:2:3. Next, the superconducting thin film 13 is fully oxidized by decreasing the temperature of the sub strate to 500 degrees Centigrade. By causing Si elements to be diffused from a Si thin film 12, parts of the super-conducting thin film which are laid on the Si thin film 11 become weak connecting portions 13b, and the other parts become superconducting portions 13a. Accordingly, a superconducting element having a magneto-resistance effect is provided with the superconducting portions and weak connecting portions alternately arranged in a row, and hence it is possible to increase a signal-to-noise ratio because of the existence of a plurality of the weak connecting portions.
