Abstract: PURPOSE:To improve the resistance to heat and wear of an aluminum disk rotor for the light-load automobile and industrial machinery. CONSTITUTION:A roughly shaped disk rotor is formed from a mixture of the powder of aluminum or an aluminum alloy and reinforcing grains. Alternatively, a mixture of the powder of aluminum or an aluminum alloy and reinforcing grains or the preform of the mixed powder is set at the specified site of the roughly shaped disk rotor, dad the mixed powder or the preform is heated to the semimolten state and press-formed. The obtained rotor is high in friction coefficient as compared with the conventional product, the wear of the rotor itself and the counterpart friction material is reduced, and the sliding surface of the rotor is kept smooth.

Title: Semiconductor device and manufacture thereof
Inventor: WAKE SETSUO
IPC: H01L29/788
Filed: 1989-03-31
Abstract: PURPOSE:To optimize operating characteristic at each of first and second transistors by setting different forming widths of gate electrode sidewalls between the first and second transistors formed on a semiconductor substrate. CONSTITUTION:Stopper thin films 31 are respectively formed on gate electrodes 10 and 18 of memory and peripheral transistors Q1 and Q2. The films 31, 32 respectively protrude from the electrodes 10, 18. In this case, the widths L1, L2 of sidewalls 11', 19, can be accurately formed at different values by altering the protruding lengths l, k of the films 31, 32. Accordingly, the optimum sidewall widths, i.e., forming widths of N<-> diffused regions 4, 5, 14, 15 can be set in the transistors Q1 and Q2. Thus, the operating characteristics of the transistors can be optimized.

Title: Lead frame having structure preventing package cracks
Inventor: OGINOME NOBORU
IPC: H01L23/50
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To obtain a lead frame having endurance to thermal shock, by forming trenches whose width is less than the filler diameter of sealing resin, in such a manner that the trenches stretch as far as the outside of a resin sealing part, on at least one surface of a tab and a tab suspension lead. SOLUTION: Trenches 17 are formed on the backs of a tab 13 and a tab suspension lead 15. The trenches 17 are formed along the periphery of the back of the tab 13, and stretched to combine with the trench from the tab suspension lead 15. As a result, the trenches pass the tab suspension lead 15 from the tab 13, and continuously reach an outer frame 11. By forming the treches in this manner, water content in a resin sealing part passes collectively the trenches 17, and effectively discharged outside. Thereby water content collecting in a part between the tab and a semiconductor element is made to easily escape. After the semiconductor element is resin-sealed, residual water content is reduced. Since the residual water content is little, package cracks are not generated when thermal shock is applied.

Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory which can be subjected to DC voltage test in package state by providing a plurality of bonding pads to be connected electrically with the outside in package state, an internal DC voltage generator, a switching control means, etc. SOLUTION: When a test is performed in package state, a test drive signal is fed to bonding pads 44, 46 and a switch control means 70 is enabled to generate a switch control signal. In response to the signal, a switch 60 is turned on to connect the output from an internal DC voltage generator with a bonding pad 42 through the switch 60 and thereby the level of generator 50 can be measured from the outside. At the time of normal operation, the means 70 is disabled to generate no switching control signal and the switch 60 is kept in off state. Consequently, the pad 42 is isolated electrically from the generator 50 and used as a general control pad for communicating the signal generated from the internal circuit.

Abstract: PURPOSE:To make uniform development by supplying a developing soln. from a developing soln. supply port which moves back and forth in the transverse direction orthogonal with the conveying direction of a printing plate onto the printing plate via a roller, brush or plate body. CONSTITUTION:A PS late which is subjected to image exposing is fed by a conveying roller pair 1 to a developing section where the developing soln. is dropped onto the transfer roller 3 from a nozzle 2 moving back and forth in the transverse direction orthogonal with the conveying direction. The developing soln. transfers on the surface of the roller 3 and is supplied onto the surface of the PS plate. The PS plate is further rubbed by a rotary brush 5 and the developing soln. is squeezed therefrom by squeezing rollers 6. The PS plate is then conveyed to a rinsing section by a conveying roller pair 7. The developing soln. is stored in a tank 8 and is fed to the nozzle 2 by a pump 9. The used developing soln. is stored in a waste liquid tank 10. The uniform development is thus executed with a relatively small amt. of the developing soln. and the cost required for the developing process is reduced. The uniform developing property is obtd. even if many sheets of the PS plates are processed.
