Title: Compound semiconductor integrated circuit
Inventor: TAKAHASHI JUN
IPC: H01L29/47
Filed: 1989-09-27
Abstract: PURPOSE:To enhance a property resistant to soft errors by a method wherein, in a circuit where source regions and drain regions of a plurality of FETs and a semiconductor layer whose conductivity type is opposite to that of an active layer have been provided, a groove which is deeper than the semiconductor layer is formed between the FETs. CONSTITUTION:A p-layer 2 and an n-layer 3 are formed on a semiinsulating GaAs substrate 1. Then, a WSi-based Schottky electrode 4 is formed; after that, ions are implanted to form an n<+> layer 5. Then, sidewalls 8 of the electrode 4 are formed; after that, an n<+> GaAs layer 7 is grown selectively. Then, a photoresist is applied to parts of the layers 3, 5; after that, a wet etching operation is executed to form a groove 20; after that, an ohmic electrode 6 is formed. Thereby, FETs are constituted. A buried film 15 of SiO2 is applied onto them, and the groove 20 is filled. When the groove 20 is formed to be deeper than the layer 5 between the FETs, electric charges to be collected can be reduced and a property resistant to soft errors is enhanced.

Title: Compressor control device of heat-pump type air conditioner
Inventor: KAWAHARA SADAO
IPC: F24F11/02
Filed: 1985-11-07
Abstract: PURPOSE:To protect a compressor with fine lubricating performance being maintained by converting the frequency of an ordinary commercial power source into necessitated frequency after each signal for bearing temp., rotating speed, etc. in addition to a detected room temp. is included. CONSTITUTION:Room temp. (t), compressor bearing temp. TS, compressor lubricating temp. TO, and a compressor rotating speed N are detected by a temp. sensor 9, a thermister 10, a thermister 11, a rotating speed sensor 12 respectively. When there is a difference between detected temp. t and the setting temp. tO, supplied frequency is selected to bring t near to tO. When t is nearly equal to tO, the previous frequency is kept. After TS/TO is compared with a setting value K, supplied frequency is the same as before in case of TS/TO<K. In case of TS/TO>=K, the case is considered to be just before seizure and after N is compared with the setting rotating speed NO, supplied frequency is determined to frequency corresponding to a rotating speed N+n (n: finely cut constant) in case of N<NO. In case of N>=NO, supplied frequency is fixed to frequency corresponding to a rotating speed N-n. A frequency conversion part receives said changes to convert the frequency of an ordinary power source into necessitated frequency and applies it to a compressor 2.

Title: Low dust production disk assembling hand
Inventor: KUZE TSUTOMU
IPC: G11B25/04
Filed: 1987-10-02
Abstract: PURPOSE:To minimize dust production by providing a mechanism adsorbing contactless a disk to an assembling hand and a contact preventing mechanism forming a gaseous film to a slight gap between a disk and a cylinder or a spindle from a gas supply hole so as to support them contactless. CONSTITUTION:A gas supply hole 6 and a gas discharge hole 7 form the contactless adsorbing mechanism of a disk and the gas supply hole forms a contact preventing mechanism to prevent the contact between a spindle 2 and a spacer 3/disk 1. Since the air blown from the air supply hole 6 is compressed, the hole diameter is smaller than that of the gas discharge hole 7. On the other hand, the two gas discharge holes 7 are provided on both sides of the supply hole 6 and since an external air is hardly suctioned, the hole diameter is comparatively large. The disk 1 is adsorbed to the adsorbing face 5 by a pressure difference between the supplied gas and the discharged gas. Since the insertion and extraction of the disk to/from the spindle or cylinder are applied completely contactless, the disk is assembled with high clean state, then a large effect is given to improve the quality of a magnetic disk device or the like.

Title: Double screen television reciver
Inventor: SHIRAI KAZUYUKI
IPC: H04N5/45
Filed: 1990-09-18
Abstract: PURPOSE:To prevent doming by using an ABL signal showing the brightness of an entire screen including master and slave screens by providing a first luminance control circuit for the master screen, second luminance control circuit for the slave screen, slave screen inserting circuit, cathode ray tube and control means to control the luminance control circuits. CONSTITUTION:When the screen is dark, the luminance of the slave screen is controlled to be lowered on the screen of the cathode ray tube for preventing doming. When the screen is bright, the luminance of the master screen is lowered by an ABL operation 28' and the luminance of the slave screen is increased in a video chroma circuit 19. By matching the pedestal levels of the slave and master screens, however, the luminance of the master screen starts lowering and is lowered a little on the screen of the cathode ray tube. This lowering amount of the luminance is set to be worked even when adding the increase of the luminance of the slave screen in the slave screen inserting circuit. Thus, when the master screen of the cathode ray tube is dark, the slave screen on the screen of the cathode ray tube is made dark as well so that the generation of doming can be prevented.

Title: Semiconductor package and its manufacture
Inventor: MAKIMOTO SHINSAKU
IPC: H01L23/50
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor package which can be enhanced in mounting density, improved in handling in assembly, and lessened in manufacturing cost, by a method wherein inner leads are provided for both leading side edges of a lead frame by etching the undersides of the leads so as to leave a lead exposed surface that serves as a board mounting surface unremoved. SOLUTION: Etching points EP1 to EP3 are subjected to half-etching so as to leave a load exposed surface 1a and an island 1b on the lead of a lead frame LF for the formation of an inner lead 1. The inner lead 1 and a package main body 13 which is nearly U-shaped in cross section and provided with a cavity 15 are formed integrally by injection molding. By this setup, a lead frame is not requiring a bending process and outer leads are not required to be subjected to a bending process, so that a semiconductor package can be realized at a lower manufacturing cost. A bending process can be dispensed with, so that the lead exposed surface 1a and the underside of a package can be improved in coplanarity. Therefore, the package can be enhanced in housing properties when it is mounted on a board for assembly.
