Title: Manufacture of semiconductor device
Inventor: YAMAGISHI KUNIHIKO
IPC: H01L29/78
Filed: 1986-08-28
Abstract: PURPOSE:To prevent the generation of bubbles in a melting process after depositing a passivation film by thermally treating the whole at a high temperature before depositing the passivation film after implanting BF2 ions. CONSTITUTION:When the ions of BF2 as an impurity are implanted into source drain diffusion regions 6 in a P channel type MOSFET element, the whole is thermally treated at a high temperature before depositing a film after ion implantation. An element isolation region 2, a gate oxide film 3 and a gate electrode 4 are formed to a semiconductor substrate 1, and BF2 ions 5 are implanted into the source-drain diffusion regions 6 as the impurity ions 5. Rapid annealing is conducted for several seconds by using a heat source 7 such as a halogen lamp, a passivation film is deposited, and melting is performed. Accordingly, fluorine remaining in Si or an Si oxide film after implanting BF2 ions 5 can be diffused to the outside through annealing, thus inhibiting the generation of bubbles under the passivation film 8 in a melting process.

Title: Semiconductor filter
Inventor: IKEDA HIROSHI
IPC: H03K5/01
Filed: 1989-07-31
Abstract: PURPOSE:To send a signal caused by on/off of a signal input switch accurately by constituting a pull-up or a pull-down element used for each filter circuit of plural signal input systems of a transistor(TR) and operating it with a reference voltage from a reference voltage source in common. CONSTITUTION:With a reference voltage set by a reference voltage generating circuit 31 fed to a control terminal for a pull-up or pull-down TR 25, the TR 25 acts like a constant current source. Thus, the dispersion in the pull-up or the pull-down element is suppressed and an input voltage level of filter circuits 211-21n at signal switch ON or OFF is suppressed lower. Thus, it is possible to take a threshold voltage of a comparator 27 low and the noise margin of the filter circuits 211-21n is improved and accurate signal transmission is attained.

Title: Washing machine
Inventor: HIRAMATSU MASAHIKO
IPC: B60S3/04
Filed: 1990-07-27
Abstract: PURPOSE:To simplify washing work by interlocking a rocking force imparting means with operation of a selector means, while controlling a rocker arm so as to be rocked only at the rear in the rocking direction of a washer body, and securing a washing range even in the return process as in an outward process. CONSTITUTION:When a washer body 1 gets retreating and a return process is started, two arms 35, 35' pass through a maximum hanfover position, and shift to the side of a front edge 10c of a carriage 10. Accordingly, each rocking range of these arms 35, 35' in the return process comes to symmetrical ranges in the longitudinal direction with that of the outward process. Since these arms 35, 35' are made rockable in the same range as the outward process even in the return process, a washer A is able to secure the same washing range even in both outward and return processes, thus an washing effect is made yet more better. In addition, since there is unnecessary to set up a detecting means such as a detecting lever or the like in advance, washing work can be simplified.

Title: Drain pipe for underdrain
IPC: E02B11/00
Filed: 1992-07-03
Abstract: PURPOSE:To maintain satisfactory drainage for a long time without clogging or joint shift and with a high strength. CONSTITUTION:A cylindrical pipe wall 1 is formed of a filter material 4 in which thin but wide stretched resin braids 2 are square-woven and the wefts and warps are welded together at their crossings. The weave-pattern gives filtering holes 3. The uniform filtering action is effected over the entire surface of the wall 1 without joint shift caused by the welding at the crossings, and since it is formed from the stretched braids 2, the tensile strength thereof is high so that it may be durable for a long time. Further, without a pipe wall 1 being fused to the outer peripheral surface of the pipe wall 1 through the intermediary of a low melting point resin adhesive layer 6, a reinforcing braid 5 is spirally wound on and integrally incorporated with the wall 1 so as to ensure a torsional strength and a pressure-proof strength.

Title: Integrated semiconductor laser
Inventor: OSAWA JUN
IPC: H01S5/40
Filed: 1985-09-12
Abstract: PURPOSE:To vary equivalent refractive indice Ne, i.e., propagation constants, of respective waveguides and make the waveguide with a larger equivalent refractive index have a smaller propagation loss alpha and obtain a high output light beam by a method wherein a distance between a layer which functions as an absorbing and reflecting element for a guided light and an active layer is gradually varied every one of parallel stripes. CONSTITUTION:A quintuplex-stripe part 14 is an inclined active layer which is formed with an inclination against a current blocking layer 2 so as to make a distance between the active region and the absorbing region (current blocking layer) varied every waveguide. By this injection of a current, the parts of the active layer above the stripe shape trenches 8 are turned into active regions and five elements make oscillation while being coupled with each other. As the larger the distance between the inclined active layer 14 and the current blocking layer 2, the smaller the influence of absorption and reflection of the layer 2 in the region where a P-type AlGaAs lower cladding layer 3 is relatively thin, an equivalent refractive index Ne is large and a propagation loss alpha is small. By the effect that light converges into the part where an equivalent refractive index Ne is large, the shape of the light distribution of a basic array mode is biased to the left and the propagation loss alpha becomes smaller toward the left side. In other words, the mode gain to the basic array mode becomes larger than the mode gain to a higher degree mode so that the lateral mode of the integrated laser can be controlled to be the basic mode.

Title: Injection mold
Inventor: ARAI TAKASHI
IPC: B29C45/26
Filed: 1990-07-31
Abstract: PURPOSE:To cool and solidify a product in a short period of time and make the shortening of molding cycle time possible by a method wherein the tip part of a core pin, which is made of a heat pipe and the tip part of which serves as the heat absorbing part of the heat pipe and the base end part of which serves as its heat discharging part, is inserted in at least some part of a cavity so as to cool said heat discharging part with cooling medium. CONSTITUTION:When thermall molten resin is poured from a resin inlet 5 with an injection molder, the molten resin is filled in a cavity 4 and a cavity 7 for a boss. By running cooling medium such as cooling water or the like in a cooling medium passage 20 simultaneously with the finish of the filling of the resin, the base end part 17 of a core pin 14 is cooled at a hollow part 19. On the other hand, since the tip part 16 of the core pin 14 is inserted in the interior of the cavity 7 for boss, the tip part is directly heated by molten resin. However, since the core pin 14 is made of a heat pipe, the heat of a boss 7a is removed so as to be able to cool the boss effectively. In other words, by absorbing heat at the heat absorbing part of the core pin 14 and discharging heat at its heat discharging part and, at the same time, by cooling its heat discharging part with cooling medium by the principle of a heat pipe, the thickwalled parts such as a boss and the like can be cooled in a short period of time by means of the tip part 16 of the core pin 14.

Title: Microcomputer
Inventor: KIUCHI TOYOO
IPC: G06F9/32
Filed: 1988-08-12
Abstract: PURPOSE:To prevent the increase in the chip area in the case of integrating the system on an LSI chip, to reduce the cost and to improve the yield by rewriting plural coefficients before a product sum arithmetic processing is started at the succeeding period after the product sum arithmetic processing by one period is finished in the write of the coefficient. CONSTITUTION:While a signal 124 is at a low level, when a pulse is inputted onto an external Fs-RST signal line 119, an instruction in an instruction RAM 1 is executed sequentially from the address 0. A signal on a HALT signal line 122 outputted resulting from decoding a revision inhibit (HALT) instruction of an address 141 is masked because the signal 124 is at a low level. Then an SR flip-flop 11 is not set and an address data after an address 142 and its succeeding addresses and a coefficient data are written. Since the content of a coefficient RAM is able to be rewritten during the idle time of the product sum arithmetic processing time in this way, the product sum arithmetic processing is not interrupted. Moreover, it is not required to provide a larger capacity for the coefficient RAM 5 than that of number of words of the coefficients.
