Title: Ferroelectric liquid crystal electro-optical device
Inventor: SHIMODA SADAYUKI
IPC: G02F1/133
Filed: 1987-04-30
Abstract: PURPOSE:To obtain high contrast by switching rewriting crest values in a first frame and a second frame by using a transistor. CONSTITUTION:When a HIGH voltage is inputted to a gate of a transistor TR 17, the TR 17 conducts and a power supply voltage VLC of a negative side is outputted to an output V5. When a LOW voltage is inputted to the gate, the TR 17 becomes nonconductive, and when a resistance value of a resistance 16 is denoted as R16, a voltage of N.R.VLC/(N.R+R16) is outputted to the output V5. N denotes a bias value, R denotes a resistance value of resistances 11, 12, 14 and 15, and at the time of selecting the bias value to N, it can be executed by selecting the resistance value of the resistance 13 to (N-4)R. In such a way, the high contrast can be obtained.

Title: Cultivation of yeast
Inventor: FUKUDA HIDEKI
IPC: C12N1/16
Filed: 1979-08-23
Abstract: PURPOSE: The yeast is removed from a part of the culture medium taken out of the cultivation tank and made to return to the cultivation tank, simultaneously a part of the filtrate is pasteurized and made to return to the tank, thus producing the yeast with effective exclusion of undesirable microorganisms and no reduction in the activity of the yeast.  
     CONSTITUTION: A part of the culture mixture in the cultivation tank I is introduced in the yeast separator II (arrow 2) and the separated yeast is made to return to the tank I (arrow 3). In the meantime, the liquid separated is sent to the pasteurizer III (arrow 4) and sent through a pipe line back to the tank I (arrow 5). Since the yeast is not subjected to pateurization, the activation becomes not low, whereas undesirable microorganisms in the liquid are deactivated or killed by the pasteurization. The pasteurization treatment is, e.g., one with a chemical such as an acid, base or hydrogen peroxide. The addition of a carbon source as the major nutrient and other nutrients or aeration, when the cultivation is conducted aerobically, is preferred with respect of preventing the reduction in yeast activity.

Abstract: PURPOSE: To control the injection time and period of the fuel injector in an intake pipe and the engine output and reduce the fuel cost in a spark ignition engine with the subsidiary combustion room which communicates to the main combustion room.  
     CONSTITUTION: The air from the air cleaner 31 passes through the main intake port and valve and flows into the main combustion room 22. It also passes through the subsidiary intake port and valve and flows into the subsidiary combustion room 32. The air volume taken in both combustion rooms 22 and 32 is constant independently of the treading-in of an accel pedal. When the intake valve opens, the output voltage pulses from the controller 54 change, are applied to the fuel injection valve 46, and adjust the fuel injection time and period, in accordance with the treading-in of the accel pedal and the rotational frequency of an engine. In the light load range where the treading-in of the accel pedal is small, fuel is injected at the later part of intake period and used effectively.

Title: Inspecting method for printed board through-hole
Inventor: AKIMOTO TAKESHI
IPC: H05K3/00
Filed: 1987-05-01
Abstract: PURPOSE:To securely detect a through-hole void which causes the breaking of a wire eventually owing to the expansion of a defect with the passage of time during actual use by conducting an electric continuity test between two ends after soft etching is applied to the through-hole to be inspected. CONSTITUTION:A through-hole 3 is formed in a printed board 7 and the through- hole void 1 is generated there.

This soft etching treatment is an etching treatment which removes conductive metal of, for example, about 5mum such as copper, silver, and aluminum by performing etching slightly. The section of the through-hole in a complete wire breaking state is formed by this treatment. This through-hole void 2 which enters the complete wire breaking state has its electric continuity checked in the period by using a normal continuity tester 5 and abutting conductive probes 4 on the both end parts of the object through-hole 3 to easily and accurately detect the through-hole void which is broken or nearly broken.

Title: Waveform modulation inverter
Inventor: IWAMOTO KUNIZOU
IPC: H02M7/48
Filed: 1978-09-04
Abstract: PURPOSE: To facilitate a ready filtration of a wave by reducing the content of lower harmonic waves in the wave by specifying the predetermined range of pulse duty factor.  
     CONSTITUTION: The half cycle of waveform modulation inverter is so limited as to contain a plurality of odd using pulses and also to be divided into 64 or magnification of binary at time points in a manner that the amplitude of each pulse is multiplied by the pulse duration time and the total of the products is divided by predetermined amplitude to thereby obtain a pulse duty factor of 0.6563∼0.6875. Thus, the lower harmonic waves contained in the generated pulse of the inverter are entirely restricted to thereby reduce the filter in samller capacity and to reduce the number of pulses so as to reduce the commutation loss of the inverter.
