Patent GB-2072943-B (GB)
Title: Piezo-electric crystal vibrator
IPC: H03H9/215
Filed: 1981-03-02
Granted: 1984-01-04
Abstract: A mode coupled tuning fork type quartz crystal vibrator utilizing two different vibrational modes is provided. The vibrator includes at least one electrode on each tuning fork arm for adjusting the resonant frequency of the main vibration and an electrode for adjusting the frequency-temperature characteristic of the vibrator. The main vibration is in the flexural mode (F1) and the sub-vibration is in the torsional mode (T0). The resonant frequency of the first overtone in the flextural mode is designated by fF and the resonant frequency of the fundamental vibration in the torsional mode is denoted by fT. The difference between fF and fT defined as  DELTA f=fF-fT determines the frequency-temperature characteristics of the mode coupled vibrator. The electrodes for adjusting fF are substantially triangular in shape and the electrodes for adjusting fT are substantially rectangular in shape. These electrodes are disposed at positions near the top of each tuning fork arm and on both principal surfaces of the vibrators. The resonant frequencies are adjusted by removing a portion of electrode material or adding a strip of metal to the electrode. Preselected oscillation frequency and frequency-temperature characteristics in the form of a cubic curve at ambient temperatures are obtained by first adjusting  DELTA f to a preselected value  DELTA fO and then adjusting fF to a preselected value fF0 at the same time maintaining  DELTA f at the value  DELTA f0.

Title: Solid state image sensor
IPC: H04N5/341
Filed: 1981-11-09
Granted: 1984-07-04
Abstract: A solid state image sensor, in which the same gate voltage is applied through a gate insulating layer to a channel area and an over-flow control gate area, both provided in a semiconductor substrate, is disclosed. In this case, the substrate concentration adjacent the area beneath the over-flow control gate area is made different from that adjacent the area beneath the channel area to reduce the gate voltage dependency of the potential at the over-flow control gate area as compared with that at the channel area, whereby the maximum handling charge upon the charge transfer mode is made more than that upon the light receiving mode.

Title: Information retrieval system
Inventor: HORIGUCHI TOSHIO
IPC: G11B27/026
Filed: 1985-03-19
Granted: 1988-06-08
Abstract: An information retrieval system for retrieving image information with the aid of retrieval information has a non-erasable first record region for recording the image information and a second record region for recording the retrieval information, which are separated from each other. Then, the desired image information is retrieved from the first record region in accordance with the retrieval information. Therefore, important image information can not be erased even if an operation is wrong and a bit unit price of information to be recorded can be made inexpensive. A first embodiment uses two regions of an optical recording disc for the record regions. In a second embodiment the first, second regions are on an optical disc, floppy magnetic disc, respectively. A third embodiment uses a hybrid optical-magnetic disc where the optical, magnetic recording regions are displaced radially from each other on the same disc.

Title: Thermal energy converting assembly - has rotary hub with temp. sensitive metal alloy strips strained by twising or bending
IPC: F02B/
Filed: 1977-05-12
Granted: 1985-05-08
Abstract: A housing rotatably supports a central hub with temperature sensitive metal alloy strips extending radially from the hub for coacting with a cam which sinusoidally strains the strips during one phase and allows the unstraining of the strips during a second phase. The strips are made of a material which undergoes a thermoelastic, martensitic phase transformation whereby in a relatively cold condition it takes less energy to strain the strips than in produced from the strips as they become unstrained when subsequently subjected to a hotter condition. In one embodiment the strips are strained by twisting as a result of a lever arm attached to the ends of the strips and reacting with the cam. In a second embodiment, the strips are strained by bending as push rods are associated with the distale ends of the strips and have rollers coacting with the cam.
