Patent DE-4041270-A1 (DE)
Inventor: LIEDKE VOLKER
IPC: B23K31/02
Filed: 1990-12-21
Abstract: During the pickling process in the novel method of soldering electronic printed circuit boards, in particular component-carrying printed circuit boards, a condensable auxiliary substance, for example water, is first adsorbed in defects in the oxide layers on the solder connection pads and at least partly condensed in the defects. The oxide layers are then subjected to such fast heating that the auxiliary substance condensed in the defects explosively evaporates and consequently breaks up the oxide layer, which detaches itself from the metallic base material in such a way that the solder connection pads are converted to a virgin state for the subsequent soldering process itself. In the case of wave soldering, the fast heating is preferably carried out by the solder wave itself. If nonoxidic passive layers have also to be removed by pickling, this is preferably done in a preceding step in the pickling process, during which the oxide layer is rendered hydrophilic. A plasma pretreatment is suitable for this purpose. The novel apparatus has a moistening chamber in which the condensable auxiliary substance is presented to the hydrophilic oxide layers and is adsorbed by the latter.

Patent DE-4137720-A1 (DE)
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/27
Filed: 1991-11-15
Abstract: An injection molding thermal gated nozzle having a nose portion which extends forwardly to the cavity. The nozzle has a melt channel which extends through the nose portion to form the gate. An integral electric heating element has a forward portion with a generally rectangular cross section and a number of adjacent coils which form an inwardly tapered inner surface. Part of the inner surface of the forward portion of the heating element forms an inwardly tapered portion of the melt channel adjacent the gate. This direct contact of the heating element with the melt reduces considerably the cycle time of the thermal gate. The forward portion of the heating element is shaped by compressing it between tapered dies. It is then mounted between forward and rearward portions of the nozzle, and the assembly is integrally brazed together in a vacuum furnace. <IMAGE>

Title: Video recorder with additional digital signal recording head - uses whole and part depth of magnetic tape coating for analogue and digital signal tracks respectively.
Inventor: KLUTH HANS-JUERGEN DIPL ING
IPC: H04N9/835
Filed: 1992-01-08
Abstract: The video recorder has two heads (K1, K2). The first head (K1) records an analogue signal comprising 3.8 to 4.8 MHz FM luminance picture carriers (BT) and a colour carrier (Fm) offset to 627 kHz on one track (A) to the full depth (So) of the magnetic layer on the tape (T). The first head has a gap of 0.4 micron and an azimuth angle of plus or minus 6 deg.. The second head (K2), with 0.2 micron gap and 30 deg. azimuth angle, records the digital signal in an upper portion (S1) only of another narrower track (B) which carries 1.4 and 1.8 MHz sound carriers (T1, T2) below the 9.7 MHz bandwidth picture signal (MPEG). USE/ADVANTAGE - Esp. for S-VHS video signals, compatible recording of digital picture signal is possible without much extra cost and with no more tape consumption.
Patent DE-4200560-A1 (DE)
Title: CCD sensor matrix for ionising radiation - has conductive connection of flat doping zone, controlling first stage potential, formed by potential separating regions
Inventor: PIERSCHEL MICHAEL DIPL ING
IPC: H01L27/148
Filed: 1992-01-09
Abstract: In the sensor, no deep-reaching channel stopper regions exist in the sensitive region, and large surface portions of a matrix cell do not have conductive gate layers. The remaining cell surface is controlled by a very thin metal gate film. Thus the cover layer extension is minimised and the generation active region depth is limited. The drain channels for parasitically generated charges and the overflow regions for excessive charge carriers are integrated. Due to very thin cover films, the ionising particles can be detected using negligible energy. Degradation effects are reduced by trimming the depth of the generation active region. USE/ADVANTAGE - E.g. for videos applications and optical radiation measuring appts., without degradation tendency, crystal interference, and with relatively small chip surface.

Title: Acceleration sensors made in silicon semiconductor material - uses an aluminium metallisation layer to protect the suspended part of the device during singulating and assembly
Inventor: ISHIBASHI KIYOSHI
IPC: G01P15/08
Filed: 1992-02-10
Abstract: The semiconductor devices feature an implanted and diffused resistor bridge (3). In the first process a thick first oxide layer is used as a mask in the etching of a trench to define the perimeter of the U-shaped suspended part of the device (1). Then the resistors are made and a metallisation layer (14) deposited. This layer is defined in a pattern to provide contacts to the measurement bridge and to overlap the U-shaped trench. A window is formed in a masking layer ion the backside of the wafer and the exposed Si is etched until the bottom of the trench on the front surface is reached. The dice are then separated and the metallisation layer linking the suspended part (1) to the substrate along the U-shaped trench is removed, pref. by mechanical breakage or by melting with a laser beam. Also claimed is the process in which the trench is not formed at the beginning of the process but after the devices have been assembled on headers, e.g. by using a laser beam. USE/ADVANTAGE - The process provides some support for the suspended part of the device which increases the yield of good devices obtained after die sepn. and assembly. The handling of the devices during mfg. can be simplified. This allows the small devices to be made more economically.
