Title: Temp. control system with electronically operated thermostat - uses generator of binary coded signal compared with reference producing error
IPC: G05D23/19
Filed: 1976-01-19
Abstract: Temp. control system which uses a thermostat to generate a control signal from a unit with a varying temperature. Thermostat operates electronically is very accurate and can be installed in a space to be kept at an accurate temp. and produces a signal which is compared with a reference. It consists mainly of a digital unit with a temp. signal generator generating a binary coded decimal number which represents the ambient temp. There is a reference signal generator which also produces a binary coded decimal number. The two binary codes are compared in a comparator and produce an error signal in binary code. The signals are produced by an oscillator with a variable frequency. The variation is produced by a temp. sensor. The digital signals are produced by counters which are fed from the output of the oscillator.

Title: Electroless nickel plating of silicon semiconductor substrate - in nickel bath contg. boron cpd. as reducing agent
IPC: H01L21/288
Filed: 1977-06-22
Abstract: The substrate wafer (a) has p-type doping, and is immersed in a Ni bath contg. a boron cpd. (b) as redn. agent. In the pref. process, wafer (a) has a surface with regions of different dopant types (n,p) and different dopant concns. and is immersed alternately in a Ni bath contg. hypophosphite as redn. agent, and a Ni bath, contg. cpd. (b). Alternatively, wafer (a) may be immersed in a Ni bath contg. both hypophosphite and cpd. (b). Wafer (a) is esp. a Si substrate, and cpd. (b) is a borohydride, esp. a borane. The Ni coating obtd. using the bath is preferentially deposited on the type 'p' zones and provides good ohmic contact, whereas, conventional baths contg. hypophosphite result in the Ni being deposited preferentially on n-type zones. When both p-and n-type zones are not present, bath still has the advantage that the amt. of B in the Ni is much less than the amt. of P obtd. in the Ni from bath.
