Abstract: PROBLEM TO BE SOLVED: To enable to test functions and static linearity of an A/D converter cell while greatly decreasing the number of external test terminals. SOLUTION: In the more sgnificant reference voltage of a suppressing A/D converter becomes lower than a normal value by mistake, a resistance block of ladder resistances which is lower in voltage than proper one is selected and the less isgnificant reference voltage is lower than an analog input voltage without fail, so that all of the output of less significant bits becomes 'H'. Namely, an area B1 wherein a current flowing to a comparator becomes constant irrelevantly to the value of the analog input voltage Vin appears. It can be decided that there is abnormality by detecting that.

Abstract: PURPOSE:To separate and synthesize laser light for erasing/recording and reproducing by constituting an optical head in such a manner that the optical paths of the 1st light beam and the 2nd light beam having a different wavelength and intersecting approximately orthogonally with the 1st beam are synthesized and separated, providing a quarter-wave plate and stop lens in the exit direction of the synthesized light beam and imaging the beam on a recording medium. CONSTITUTION:The 1st polarization beam splitter 24 has the polarization beam splitting characteristic to reflect the S-polarized light beam and allows transmission of the P-polarized light for a wavelength lambda1 and wavelength lambda2 by an optically multi-layered film 24a. A semiconductor laser 20 is so disposed that the light beam 21c of the wavelength lambda1 is made incident as the P-polarized light on the splitter 24. The beam 21c transmits the splitter 24. The 2nd polarization beam splitter 25 has no polarization beam splitting characteristic and allows transmission of the S- and P-polarized light for the wavelength lambda1. Said splitter reflects the S-polarized light and allows transmission of the P-polarized light for the wavelength lambda2. The light beam 21c having the wavelength lambda1 forms consequently a circular light spot 29 on a disk 28. On the other hand, the light reflected from the disk 28 rotates the polarization direction of the light 90 deg. and is made incident as the light beam 21d on the splitter 25 and is made incident on the splitter 24.

Abstract: PURPOSE:To allow a pump to operate in slow operating cycles, resulting in a low operating noise, by forming an actuating member using a shape memory alloy, and by utilizing extensional and contractional deformation thereof due to a change in temperature to actuate the pump. CONSTITUTION:An actuating member 16 being cooled with drain water, is extensionally deformed, for example, at temperatures under certain temperature to actuate a pump 15, causing it to pump up drain water.

Filed: 1981-06-30
Abstract: PURPOSE:To ensure proper elimination of faulty pellets without judgement by visual inspection by a method wherein the distance between an electrode built on the pellet  main surface and a pellet side wall end is determined, in a process of detecting cutouts  in a pellet generated when a wafer is divided into individual pellets. CONSTITUTION:A semiconductor wafer is divided into a plurality of PNPN four layer  thyristor pellets 1. The side walls 1a of a pellet are mesa etched and the PN junction  exposed on the main surface is covered with a protective film of SiO2 or the like.  Next, electrodes 3 and 4 are attached respectively to the P and N layers on the surface  while the P layer on the rear surface is provided with an electrode 5. A chipping 6 in  a pellet created in the sectioning process reaching the PN junction in a side wall 1a  can be a cause for rejection because of an increased leak current. To decide on the acceptability of a pellet 1, a length one half of the width of the inclined side wall 1a  is used as a reference. The side wall 1a is exposed to a small diameter light beam that  is outputted by a light source 7 and is transmitted via rotary multi-mirror reflectors 8  and 9. Reflection by the pellet side wall 1a is supplied to the light receiving unit 10 for  judgement by the decision unit 11 as to whether the given pellet 1 is acceptable or not  in terms of the quantities of light reaching the light receiving unit 10.

Title: Thermal head
Inventor: SHIBAMIYA YOSHIKAZU
IPC: B41J2/375
Filed: 1983-06-10
Abstract: PURPOSE:To achieve the reduction in running cost by prolonging the life of the whole of a head, by providing an auxiliary generator to a heat generator high in use frequency. CONSTITUTION:When a heat generator 3 high in use frequency is damaged, a damage detecting circuit 7 detects this damage state and a dot change-over signal S1 changes from a high level to a low level to inhibit the output of an AND circuit 8. As a result, the supply of printing data D3 is also inhibited. On the other hand, because the output of an AND circuit 9 comes to an enable state, the printing data D3 once stored in D flip-flop 14 is taken out of a Q-output terminal while delayed over a predetermined time and supplied to a heat generator 4 for auxiliary printing through a thermal head driver 13. Because this heat generator 4 is arranged so as to leave a distance corresponding to one dot from the heat generator 3, the delay time of the printing data D3 comes to a time equal to one heat cycle supplied to a heat generator 2.
