Patent GB-2138205-A (GB)
Title: Methods of manufacturing a microwave circuit
Inventor: WATTS RONALD STEPHEN
IPC: H01L21/58
Filed: 1983-04-13
Abstract: In the manufacture of a microwave circuit a semiconductor device body (1,2) is pressed into the surface of a circuit substrate (10) to deform the substrate (10) locally so as to form a recess (15) having substantially the same shape and depth as the device body (1,2). The device body (1,2) is held in the substrate (10) by the abutting walls of the recess (15), and low inductance connections are formed by conductive layer portions (23,24) extending directly across the adjacent edges of the device body (1,2) and of the recess (15). In this manner prior art problems associated with diode bodies in larger recesses are avoided. Deformation of the lower face of the substrate may be reduced, or insertion of the semiconductor body into substrates of less readily deformable material may be facilitated, by provision of an initial recess of smaller dimensions than the semiconductor body (Figure 4). <IMAGE>

Title: A chuck for clamping a hollow workpiece
Inventor: PFEIL ANTON
IPC: B23B31/40

Title: Electronic data storing apparatus
Inventor: ORII TOSHIO
IPC: G04G11/00
Filed: 1984-01-06
Abstract: An electronic memoranda device especially suitable for the retrieval of stored data with low energy consumption is provided. In the electronic memoranda device, days, times, and schedules, and the like, are stored in a data memory. At regular intervals a key portion of these stored times is compared with a key portion of a current time signal outputted from a timekeeping circuit. When the key portion of time data read out from the data memory coincides with the corresponding portion of the currently outputted timekeeping signal, the entire data stored in memory is scanned for coincidence with the complete timekeeping signal. Coincident data is outputted for display. When the initial survey of the memory indicates that no data is stored corresponding to the key current time unit provided by the timekeeping circuit, the inspection operation of the memory is interrupted until the occurrence of the next time unit wherein inspection of the memory is repeated.
