Title: Automatic reciprocating motion control unit
Inventor: NAGASHIMA HIROSHI
IPC: G05D3/20
Filed: 1978-07-28
Abstract: PURPOSE: To obtain the uniform characteristics and steady operation by forming the RHI automatic scan signal of the radar antenna through operation of the digital signal.  
     CONSTITUTION: The antenna is scanned with 2θ a  centering on elevation angle θ c ; and order signal 9 is applied under y=Asin ωt, where y and A show the displacement and θ c  respectively. The angular control is given by error signal 15 with delay of t to the order. Signal 15 is applied under V=k 1 A ωt and cos ωt. Now order 9 is given in the form of the digital signal after A/D conversion. While the information of the elevation angle of the antenna is changed into the digital signal via encoder 5 and then to pure binary code of the same unit through pure binary converter 6. Subtraction 7 is given to the pure binary code along with order signal 11 to then undergo D/A conversion, and then the driving control is givne to antenna 4 by analog signal 15. Thus, the reciprocating motion is controlled via the electronic method.

Title: Liquid crystal element
Inventor: KANO MITSURU
IPC: G02F1/137
Filed: 1988-04-15
Abstract: PURPOSE:To enable displaying of basically a positive mode so that the sharp, colorless and bright display is realized by using an OMI type liquid crystal element of a positive display as a base and combining a light source having large light emission energy in a wavelength range where the transmittance of the liquid crystal element body in a bright state is low with the liquid crystal element body. CONSTITUTION:The wavelength range where the light emission energy is high is confirmed by investigating the spectral characteristic of the light source which can be utilized and the respective parameters of the liquid crystal element body are set at optimum values within the range of 180 to 270 deg. twist angle and 0.4 to 0.7 retardation in such a manner that the transmittance of the liquid crystal element body decreases in the wavelength range where the light emission energy is high. The OMI type liquid crystal element of the positive display is used as the base and the light source having the large energy of the emitted light in the wavelength region of the range where the transmittance of the liquid crystal element body in the bright state is low is used and, therefore, the light of the wavelength region where the light is easily absorbed by the liquid crystal element body is much projected to the liquid crystal element body and the light transmitted through the liquid crystal element body eventually has the lower dependency on wavelength. Since the light of the wavelength region where the light is hardly transmitted through the liquid crystal element body is compensated by the light source, the colorless display is attained and the bright display of the liquid crystal element is executed.

Title: Vertical type mos field effect transistor
Inventor: KASHIWABARA AKIHIRO
IPC: H01L29/06
Filed: 1989-04-15
Abstract: PURPOSE:To remarkably improve breakdown strength by a method wherein, in a conductivity type semiconductor substrate turning to a low concentration drain region, an inverse conductivity type diffusion region turning to a channel region is formed, and a conductivity type diffusion layer whose concentration is higher than the drain region is formed around the above inverse conductivity type diffusion layer, so as to be in contact with the periphery thereof. CONSTITUTION:When an N-type source region 3 of a power MOSFET is formed inside a channel forming region (P-type diffusion region) 2, a drain region (N- type diffusion region) 10 whose concentration is higher than a drain region 1 is formed so as to be in contact with the periphery of the channel forming region 2 positioned in the chip periphery. In this case, when a backward voltage higher than or equal to a breakdown voltage is applied between source.drain, breakdown phenomena generate in a PN junction surface constituted of the high concentration drain region 10 and the channel forming region 2. The breakdown current rapidly reaches a source aluminum electrode 7 without flowing through the P-type diffusion region under the N-type source region 3. Thereby breakdown strength is remarkably improved, and further application as a zener diode is enabled.
